In some European countries, a fine is imposed for a long warm-up, and no matter how cold it was outside, so most foreign manufacturers do not recommend warming up their cars. main reason this is environmental pollution.

Below we will try to figure out whether it is necessary to warm up a diesel engine with a turbine, we will indicate all the advantages and disadvantages of warming up, as well as the nuances of the engine's functioning at different times of the year.

Features of diesel warming up

In the opinion of many, it is better not to warm up the engine with a turbine on the move, just because of the turbine, since it turns on only at the required crankshaft speed, which appears at high speed. And it is forbidden to develop high speed on an unheated engine. Driving with the turbine turned off can lead to overheating of the engine, resulting in overheating of the cylinder heads and their rapid wear.

The diesel engine needs to idle for at least 5 minutes, this is enough for all components to be lubricated normally (unless, of course, the glow plugs are in working order). The developers advise to warm up the candles twice. The extinguishing of their indicator on the panel indicates that the voltage in them has turned off, although most people think that this happens if the maximum temperature is reached.

Excessively long heating will lead to the appearance of resin deposits on the valve, because of this, the valves may begin to lock in the future.

Many experts argue that it makes no sense to warm up the engine for a long time if high-quality oil and cooling fluid are filled in. It was found that with a cold engine, the depreciation of the elements is practically absent if the car is driving at low speed. The revolutions, respectively, also do not exceed two thousand, due to which the required temperature can be reached quickly.

Diesel fuel evaporates much worse when heated. After starting the unit in a cooled engine, the fuel begins to settle on the surface of the cylinders and does not completely burn out. As soon as the temperature reaches the norm, the fuel assembly in the chamber burns out evenly and completely.

Remember that the components of the internal combustion engine do not heat up equally, some of them need more time. The heating time also depends on what material the parts of the unit are made of (usually pistons, cylinders, shafts are made of aluminum alloy, everything else is made of metal).

Good lubrication of rubbing elements and optimal setting of clearances are carried out exclusively after the internal combustion engine reaches the required temperature.

Warming up the engine in winter and summer

It is strongly recommended to warm up the engine in summer. The movement should be started only a minute after the engine has started, since it is during this period of time that all elements are lubricated with oil. To reduce the excessive load on the engine, it is better not to make sudden movements and move smoothly until the temperature approaches fifty degrees.

Diesel engine operation winter time year requires full warming up, since the oil in the engine and gearbox begins to thicken at low temperatures. The oil should become liquid and only after that you can gain high speed. The duration of the warm-up depends on the air temperature; the lower it is, the longer it will take to wait.

You should start moving when the temperature reaches 60 degrees. In this case, it is recommended not to gain more than two thousand revolutions, and the speed should not exceed twenty km / h until the normal temperature is reached. In addition, it is better not to turn on the salon stove until the engine heats up to sixty degrees, otherwise the air flow coming from it will be cold.

All of the above tips will help the driver save time and avoid further problems with the diesel unit, as well as significantly extend its life.

Pros and cons of warming up

When asked whether or not a diesel engine with a turbine should be warmed up, most manufacturers say that modern units have an injection system that allows them to start moving immediately, since oil from the surface of the liners is not washed off by the fuel due to the correct implementation of fuel spray. But still, in cold weather, diesel fuel becomes viscous and less fluid and therefore requires warming up.

Domestic manufacturers, on the contrary, advise starting movement only after the engine warms up to forty-five degrees.

Speaking about the disadvantages of warming up a diesel engine, first of all, it is worth noting the following phenomena:

• Emission of harmful substances;
• Too much fuel consumption;
• Rapid wear of the components of the gas exhaust system;
• The glow plugs are under high stress.

The advantages of diesel warming up:

• The oil is distributed optimally, the most important systems of the machine wear less, due to the fact that all the main parts are thoroughly lubricated. For example, myself power unit can work much longer;
• The vehicle moves smoothly and without jerking.

It is necessary to select the correct diesel fuel for a particular season. In addition to winter and summer fuel, there is also an arctic fuel, which is needed only at the lowest temperatures from -40 degrees Celsius. When using summer fuel in winter, diesel fuel will turn into a kind of jelly, which makes it impossible to warm it up, in addition, this will lead to clogging of the air and fuel filters.

To optimize the temperature in the combustion chamber during extreme cold, you can try switching the ignition three to five times. Then it will be easier and faster to warm up the engine.

In winter, it will take five to ten minutes to warm up a diesel engine with a turbine, and in summer about 2 minutes. No longer needed, as this will lead to overheating of the engine.

In order to carry out warming up, you must first start the engine, during the first two to three minutes it must operate on idle and only after that you can get under way. It will not be able to reach the desired temperature during this time and will continue to heat up on the fly.

Why is oil heating necessary

The operation of the engine is greatly influenced by the octane number of fuel assemblies, fuel quality, and the presence of additional additives. For an easier start, many use prestarting devices, glow plugs, etc. But still, how efficiently diesel injectors will spray fuel depends only on the temperature of the power unit.

If an automatic transmission is installed in the car, then it is necessary to warm up the engine, since the oil in the box must warm up to the required temperature.

In terms of their design, diesel engines differ from gasoline engines, first of all, in that they have not such large gaps between the piston and the cylinder. A diesel engine has an increased compression ratio, which places heavy loads on the cylinders and pistons. The rapid wear of these components lowers the oil, which thickens at low air temperatures and requires heating.

Oil for units with a turbine should be supplied even better for lubrication of the turbocharged compressor, since the operation of the turbine itself depends on it. The oil warms up at idle, do not overload the engine until it is fully warmed up.

Should I buy diesel carmobile?

All in all, a simple question that, however, is so much controversial and not so easy to answer. For example, Volkswagen has built its successful career on the TDI brand, but now it already looks rather dull, and perhaps VW will soon part with diesel cars completely. What is the general situation with the purchase of a car with a diesel engine and the reasons why this idea is better to abandon?

Diesel engines are very interesting from a practical point of view and are still very popular. Even the lobbies of large conservationists who point to environmental pollution do not change anything. However, it seems that even what is indestructible will eventually collapse and diesel engines may not be quite as immortal as one might expect. DieselGate program

It is ironic that it was Volkswagen who unleashed that tight control over the entry of certain diesel vehicles into major European cities. This is not so relevant for Russia. However, this well-known program became the reason for the bankruptcy of the very same company, we are talking about the notorious Dieselgate, after setting maximum standards for the exhaust of diesel cars, it immediately became impossible to drive a car with a diesel engine into urban areas and cities. And therefore, we have to ask ourselves again, is it worth buying a diesel nowadays? Who guarantees us that after two years we will not have to get rid of the car for a bargain price, since they will not be allowed anywhere with it? What's going on in this industry and why is the volume of diesel car production declining?

Gasoline is also not entirely clean

Most of the motorists looking for optimal car, focus on hybrids. This type of car is not prohibited or oppressed anywhere, on the contrary, the pressure from specialists and environmentalists begins to grow strongly, which is helped by cases like Dieselgate, which has become a vivid evidence of how diesel engines are harmful to the environment.

Regardless of how good a diesel car is, in any case, the harmful substances of its exhaust, even after filtration, still get into the air in larger quantities than on a gasoline one.

Yes, of course, gasoline is also not completely clean fuel. And, in any case, the time will come when fossil fuels will run out and then, instead of them, alternative fuel resources will come and, perhaps, this will happen soon enough. But despite the fact that the engine experts internal combustion, stand their ground, claiming that the particulate filter diesel system the exhaust can capture much more harmful substances than the gasoline version, while they completely forget to say that their production of harmful substances is several times higher than that of the gasoline counterpart. Germany says no to diesel

Germany is gradually turning its back on diesel engines. It was only after the Dieselgate affair that diesel vehicles were closed in several cities. Yes, there are cities in which entry with a diesel engine is simply prohibited. The Germans, indeed, are very scrupulous in matters related to diseases caused precisely by the exhaust of harmful substances during the combustion of diesel fuel.

The Germans even worked on the idea to introduce something like the corresponding road sign... They proposed a blue sticker that would already at a distance determine the movement of vehicles that can drive and restrictions for diesel. So, if we talk about the dangers of exhaust from a gasoline unit, then it should really be old carso that the pollution reaches the level of diesel pollution.

Diesel Engines Don't Die

However, we should note that car factories equip modern cars high quality particulate filters that significantly reduce the emission of harmful substances. Audi and BMW have succeeded in this. The ban on such cars is completely avoided, however, due to the use of precious metals in modern filters, the maintenance of such cars becomes more expensive. Before buying any diesel car, it is necessary that a person does not proceed only from savings, but that such vehicle was used for what it was actually intended for. This means that the vehicle will be used over long distances. Diesel cars are undesirable in urban use, short trips are better suited to gasoline counterparts.

Japanese manufacturers have reliable diesel engines. And what is the most reliable diesel engine reliable in Japan?

Let's take a look at the most common modern diesel engines in the Japanese car industry.

What are these diesels, how weak and strengths Japanese diesels. They now dominate mainly in Europe, but quite often they began to appear in Russia.

But, unfortunately, they also have problems when their runs exceed one hundred thousand kilometers, and even some up to one hundred thousand.

The caution in the supply of diesel engines from Japan is due to their capricious attitude towards fuel. Their fuel system is rather weak to the use of our diesel fuel.

Another problem is the availability of spare parts. There are practically no non-original spare parts from reliable manufacturers. Chinese ones appear, but their quality leaves much to be desired and does not at all correspond to Japanese quality.

Hence, their very high price is dictated, much higher than for German spare parts. In Europe, there are many factories producing spare parts of decent quality and at prices significantly lower than the original ones.

The most reliable diesel engine from Japan

So what's the most reliable diesel engine from Japan? Let's rank the TOP 5 of the best diesel engines.

5th place

In fifth place, you can safely put a 2.0 liter Subaru engine (Subaru). Four-cylinder, turbocharged, opposed, 16-valve. Intake system Common rail.

I must say, this is the world's only boxer diesel engine.

Boxer engine, this is when reciprocal pairs of pistons work in a horizontal plane. This arrangement does not require careful balancing of the crankshafts.

Weak sides of this engine, it is a two-mass flywheel, it broke down even up to five thousand kilometers. Crankshaft cracking, destroyed until 2009 crankshafts and shaft support.

This engine is very interesting in its design, with good characteristics, but the absence of spare parts for such engines negates its advantages. Therefore, we assign the fifth place of honor in the Japanese range of diesel engines.

4th place

The fourth place is taken by the Mazda 2.0 MZR-CD engine. This diesel has been produced since 2002, and is installed on Mazda 6, Mazda 6, MPV cars. It was Mazda's first common rail engine.

Four cylinders, 16 valves. Two versions - 121 hp and 136 hp, both developing a torque of 310 Nm at 2000 rpm.

In 2005, it underwent modernization, with an improved injection system and a new high-pressure fuel pump. Reduced compression ratio and adaptation of the engine with a catalyst for the emission of harmful gases. Power became 143 hp.

Two years later, a version with a 140 hp engine came out, in 2011 this engine disappeared from the line of installed engines for unknown reasons.

This engine quietly nursed 200,000 kilometers, after which it was necessary to change the turbine and dual-mass flywheel.

When buying, you should carefully study its history, and it is better to remove the sump and look at the oil sump.

3rd place

Also Mazda engine, Mazda 2.2 MZF-CD. The same engine with increased but increased displacement. Engineers have tried to eliminate all the jambs of the old two-liter engine.

In addition to the increased volume, the injection system has been modernized, and another turbine has been installed. On this engine, they installed piezo injectors, changed the compression ratio and radically changed particulate filter because of which there were all the problems of the previous model of the two-liter engine.

But the global struggle for the environment, both in Europe and in Japan, adds gimoro to all engines, and a system is installed on this, with the addition of urea to the diesel fuel mixture.

This all reduces emissions to Euro 5, but as always, in Russia, this adds problems to all modern diesel engines without exception. This is simply solved with us, the particulate filter is thrown out and the afterburning valve of the unburned exhaust is muffled.

The rest of the engine is reliable and unpretentious

2nd place

Toyota 2.0 / 2.2 D-4D engine.

The first two-liter Toyota 2.0 D-4D CD appeared in 2006. Four-cylinder, eight-valve, cast iron block, timing belt drive, 116 hp The engines were indexed "CD".

Complaints about this engine were very rare, they all boiled down only to the injectors and the recirculation system. exhaust gases... In 2008, it was discontinued, and instead a new one was launched, with a volume of 2.2 liters.

Toyota 2.0 / 2.2 D-4D AD

They have already begun to make a chain, there are already 16 valves for four cylinders. The block was made of aluminum with cast-iron sleeves. The index of this engine became "AD".

The engines are available in both 2.0 and 2.2 liters.

Most good feedback about such an engine, and good performance, and low fuel consumption. But there were also complaints, the main one was the oxidation of the aluminum head at the point of contact with cylinder head gasket, approximately in the period of 150-200 thousand km. mileage.

Replacing the block head gasket does not help, only grinding the cylinder head and block, and this procedure is possible only with the removal of the engine. And such a repair is possible only once, the motor will not withstand the second grinding of the head and block, the depth will be critical with the possibility of meeting the valves with the head. Therefore, if the motor traveled 300-400 thousand kilometers, with one grinding, it only needs to be replaced. It's a very decent resource though.

Toyota in 2009 solved this problem, with such malfunctions they even got new motors under warranty at their own expense. But the problem is very rare, but it does occur. Mainly for those who do not lightly ignite the 2.2-liter engine on the strongest version of this model.

Such engines are still produced and installed on various car models: Raf4, Avensis, Corolla, Lexus IS and others.

1st place

Diesel engine Honda 2.2 CDTi. The most reliable subcompact diesel engine. A very efficient and very economical diesel engine.

Four-cylinder, 16-valve, variable displacement turbocharged, common rail injection system, sleeve aluminum block.

Bosch injectors are used, not capricious and expensive Japanese Denso.

The predecessor of this engine was built back in 2003 with the 2.2 i-CTDi mark. It turned out to be very successful. Hassle-free, dynamic and fuel efficient.

Modern considered honda engine 2.2 CDTi appeared in 2008.

Of course, typical malfunctions did not pass, but they were all extremely rare. Exhaust manifold cracks, but they appeared in the first issues, the Japanese reacted and this was not observed in subsequent issues.

Sometimes there were malfunctions of the timing chain tensioner. Also, sometimes the turbine shaft play appeared prematurely.

All of these malfunctions arose from excessive constant loads and poor maintenance.

Honda installed this engine on models Honda civic, Accord, CR-V and others.

By far, this engine has the lowest number of failures and breakdowns in relation to all other engines from Japanese automakers.

We give him five points out of five, assign him the First place of honor and wish you to have a similar one on your car.

With the constant rise in fuel prices, the installation is becoming more and more popular. This is not surprising. Having spent several thousand rubles on HBO, you can drive on fuel, the price of which is half that of gasoline. Usually the installation of gas equipment is carried out on gasoline cars. Their engines are more suitable for natural or reduced gas operation. But there are also diesel cars with LPG. Can it be converted to gas? Should you install such equipment? See the answers to these questions in our today's article.

Diesel features

As we said earlier, LPG is installed mainly on gasoline engines. If we consider gas diesel, only domestic trucks MAZ and KamAZ can serve as an example. On passenger cars such equipment is not found. Why is it so rare to install gas on a diesel engine? The answer is simple, and it lies in the principle of fuel ignition.

As you know, gasoline engines ignite the mixture with the help of auxiliary devices. They are candles. When the fuel-air mixture is fed into the chamber, they generate a spark, due to which the fuel is ignited. Due to the fact that gasoline ignites from third-party devices, such engines have a low compression ratio. Now it is about ten to twelve units. And if we consider the motors soviet trucks, then even six. The only point is the octane number of gas, which is higher than that of gasoline. If for the latter it reaches 98, then for gas it is at least 102. But for the engine to work normally on this mixture, the electronic unit control automatically corrects ignition angles and other parameters in real time.

For diesel engines, there are no classic spark plugs. The mixture ignites from a high compression ratio. The air is heated under pressure so that the temperature in the chamber reaches 400 degrees Celsius. As a result, the mixture ignites and the piston travels. Someone will say, they say, there are candles in a diesel engine. Yes, some motors have them. But these are completely different - glow plugs. They make it possible to produce without difficulty by preheating the fuel. Such candles have a completely different structure and principle of operation. By the way, the minimum compression ratio for a diesel engine is 20 units. If the indicator is less, the engine simply will not start. In modern auto engines, the compression ratio can reach 30 units.

Thus, if the use of LPG on a gasoline engine does not cause difficulties during operation (since the fuel is ignited by candles), then a diesel internal combustion engine is not able to "digest" such a mixture.

Why is it difficult to convert a diesel engine to gas?

There are several factors that complicate the process of installing and operating LPG on such an internal combustion engine:

• Flash point. If a diesel engine ignites spontaneously at 400 degrees, then the gas burns at 700 and above. It doesn't matter if it is methane or propane-butane.
• Lack of candles. Whatever the compression ratio in a diesel engine, it is not enough to heat the gas mixture to autoignition temperature. Therefore, you cannot do without installing third-party spark plugs.
• Octane number. Diesel fuel has an OCH of 50 units. Gas has at least 102. If such fuel gets into a diesel engine, it will run out of control (this is uncontrolled engine operation on high revs). There are several ways to solve the problem. This is a correction of the compression ratio, or a decrease in the octane number of the gas mixture.

Installation methods

There are several installation methods:

• With a complete redesign of the engine.
• With the introduction of the Dual Fuel system.

Which one is better to use? Below we will look at what the features of each technology are.

Complete rework

What is the essence of this method? The bottom line is simple - the diesel engine is completely converted to gas. At the same time, after such an intervention, he will no longer work on his "native" fuel - only on gas.

To prevent the unit from running around, adjust its compression ratio. It is about 12: 1. Only in this way can the engine "digest" fuel with a high octane number... Next, a mixture ignition system is installed. There are no special mechanisms here. For arson, ordinary candles are used, as on gasoline engines.

What is the disadvantage of such a rework? Due to the need to carry out a whole range of works, the cost of reinstallation can reach 200 thousand or more. This is ten times more expensive than converting a gasoline car to gas. Therefore, the savings are highly questionable. Moreover, such a motor will have a decrease in power and torque.

Dual Fuel System

It is this scheme that is used on some modifications of MAZ and KamAZ trucks. it combined system fuel supply. At the moment, this is the cheapest, correct and easily implemented option. The cost of rework is about 70-85 thousand rubles. The peculiarity of the system is that there is no need to install spark plugs. To ignite methane (or propane-butane), self diesel fuel... As for the main components of the system, it is all the same gas reducer, hoses and lines, as well as cylinders for storing fuel.

How it works?

The engine is started only with diesel fuel. After that, the gas reducer is already used. It feeds the mixture into the combustion chamber through inlet valve... Gas goes along with oxygen. Along with this, a small portion of diesel enters the chamber. When the piston almost reaches top dead points, diesel fuel ignites. Its temperature is about 900 degrees, which is already enough for methane or propane to ignite spontaneously. Thus, two types of fuel are burning in the chamber at once. The efficiency of such a motor is unchanged, except that the diesel portion is reduced by an order of magnitude.

What gas can be supplied to a diesel engine? You can install both a propane system and a methane one. But there are pitfalls here. As the reviews note, the gas installed on the diesel engine shows itself in different ways. If we talk about propane, its percentage in the mixture is relatively small - up to 50 percent. In the case of methane, up to 60 percent of the gas is used. Thus, the portion of the diesel supplied to the chamber is reduced. This has a positive effect on savings. But it is impossible to completely limit the diesel supply. Otherwise, such a mixture simply will not ignite without extraneous sources.

Is it profitable?

Consider the feasibility of converting a diesel engine to gas. Since such an engine still needs a portion of the original fuel (in our case, diesel fuel) to operate, the savings are not so significant. If gasoline engine completely runs on gas, the cost of fuel costs is reduced exactly by half. But in our case, the savings will be only 25 percent, or 1.5 times. And this despite the fact that the price of installing the Dual Fuel system is at least 70 thousand rubles.

It is not difficult to calculate how much mileage this system will pay off. Under favorable conditions, the payback of LPG on a diesel engine will come in 70-100 thousand kilometers. And only after this run will you start saving. That is why gas is supplied to a diesel engine only in rare cases, and even then - for domestic trucks. Such a system practically does not occur on passenger cars.

Summing up

So, we found out if it is possible to install gas on a diesel engine. In view of the different principle of operation, the installation of LPG on such a motor requires major alterations. And as a result, this unit will still require a small portion of the diesel engine. There are savings from the use of such equipment. But it is so insignificant that no one bothers about the question "is it worth installing gas on a diesel engine." High payback periods and complexity of installation are the main factors that prevent the use of gas equipment on a diesel engine.

Borshchik is red, but without beets. Well, or something like that. You can describe the technology of a diesel engine that fully uses gasoline as fuel. This is Mazda baby, developed the innovative Skyactive-X engine.

Engineers at the Japanese car manufacturer Mazda have developed new engine internal combustion Skyactive-X, which will be installed on new cars from 2019. The Japanese used the diesel cycle, but the fuel is gasoline.

This is a fundamentally new power plantcombining diesel cycle and gasoline as engine.

As you know, diesel is a piston internal combustion engine with compression ignition. It uses diesel fuel and is very economical. The difference between a diesel engine and a gasoline engine is that in the first case, the fuel ignites spontaneously when supplied to the cylinder with pre-compressed air. A diesel engine has a much higher compression ratio in cylinders than a gasoline engine. In general, diesel is simpler in design than gasoline counterparts, and its cycle is more economical.

The new SkyActiv-X ignites the air / fuel mixture without sparking - by compression, just like a diesel engine. By combining a compression system with a supercharger, Mazda was able to increase torque. The concept used allowed the Japanese to simultaneously increase engine power and reduce pollution.

The ideal diesel cycle is characterized by four stages: adiabatic compression of the working fluid, isobaric supply of heat to the working fluid, adiabatic expansion of the working fluid, and isochoric cooling of the working fluid.

Note that now all automotive companies are actively working to improve the efficiency of their offspring, which is not least due to the rapid spread of electric cars. Mazda itself says the Skyactive-X will be 20-30% more economical than the company's other gasoline engines. Such giants of the global automotive industry as Daimler and General Motors are already interested in the new development of the Japanese. Mazda will probably share the details of the new product later. It is known that the company's management plans to start installing Skyactive-X on cars starting in 2019.

The new engine is part of the Japanese automaker's strategic plan to electrify and minimize emissions. The plan is calculated until 2030. Mazda wants to join forces with Toyota and create new electric vehicles. Meanwhile, Japanese specialists are clearly in no hurry to abandon the "gasoline" direction, which they have repeatedly made clear.

How are things at the moment? What happens if gasoline is poured into a diesel engine and how it behaves gas engine when using diesel fuel?

"Dummies" or "blondes" do not always get into such situations, often even experienced drivers can get screwed up. You know, I myself was a witness of this situation - I have an acquaintance who bought a second car for his family (he also has one worker) - that is, only three cars. Long dreamed of powerful SUV - in his opinion, in order to save money, he nevertheless took diesel (for a long time he chose diesel or gasoline). AND old car, he left a sedan for his wife. In general, as usual, I drove to the gas station after a really difficult working day (it's easier to say the brain was taken out) and got up to the gas station with gasoline, purely by inertia - then I just poured gasoline into the diesel engine! Realization came only after a couple of kilometers, when the car began to twitch and behave somehow strangely.

To begin with, it should be noted that gasoline and diesel are essentially different, two types of fuel. Engines operate on different principles, although both there and there are pistons and a crankshaft with connecting rods.

Ignition principles of liquids

Petrol... The most common type of engine, and therefore remember it first.
Remember that it is a four-stroke (injection, compression, ignition, exhaust gas outlet). But the principle of ignition here is based on spark plugs, and they ignite the fuel mixture (gasoline + air), which is supplied through the intake manifold. Without the candles, the fuel would not ignite, although in fairness "detonations" sometimes occur, but very rarely. It is also worth noting that the compression in the cylinders is approximately from 9.5 to 11 atmospheres, this is important! Of course, now there are SKYAKTIV engines from MAZDA, where the compression reaches 13.5, but still this is an exception to the rule, rather than a general trend.

Diesel (in Russia it is also called "diesel fuel").
There are also four strokes (injection, compression, ignition, exhaust). But the fuel is ignited differently, there are no spark plugs at all, and the injection is completely different here. Firstly, I would like to say that the ignition of diesel fuel occurs due to compression (compression on diesel engines reaches 20 atmospheres). Secondly, the fuel does not mix with air and is not supplied as a fuel mixture - there is separate air and diesel oil separately. How everything happens - the piston compresses the air in the cylinder, because of which it heats up very much, then almost at the peak point, fuel is injected, under very high pressure (through the nozzles), after which it ignites.

As you can see, the differences are significant, outwardly similar units, very different inside, and the fuel supply system is different here.

What will happen if you pour gasoline into the "diesel"?

It's not very good to say the least. However, it all depends on how much gasoline you added, it happens that you have a tank of 100 liters, and you "splashed" only 5 liters, then the diesel engine most likely simply will not notice it - it will "chew" like a nice little one. I talked with seasoned truckers, so before the appearance of "diesel antigels" they added a little gasoline to the tank so that the diesel was not so thick in the cold, they say - it really helps. However, the addition should be within 3%, well, maximum 4 - 5, no more!
However, if a lot was flooded, more than half or almost full tankthen it can have a detrimental effect on the diesel engine, or rather on its systems. What happens at the beginning? Yes, everything just your car will stop and will not start. The thing is that, as I wrote from above, a spark is needed for gasoline, but compression is like “on the drum”. Respectively normal work will fail and the engine will stall.
In the tank and the car system, there are fine and coarse filters, they are designed for diesel fuel, and if gasoline gets into them, and it is more "active" and liquid, then it will simply "kill" them. Definitely a replacement.

A terrible word for all owners of diesel engines - injection pump ( fuel pump high pressure) + associated injectors that inject this fuel into the cylinders.

So they are "sharpened" for a diesel engine! "How does it manifest?" - you ask. Yes, everything is simple, modern diesel fuel, so to speak, is oily fuel, the composition contains a small amount of lubricating compounds, it is they who lubricate the injection pump and nozzles, prolonging their life. But in gasoline there is no such thing, on the contrary, it is an excellent solvent, that is, it washes away all lubricants. Also, gasoline is much thinner, it has a completely different consistency. So these important elements may fail - and this is oh, how not cheap, if you change all 4 nozzles + the pump itself, then this is about 20-30% of the cost of your car. I remember that cleaning one injector with disassembly on a Volkswagen TUAREG cost 14,000 rubles, and this is not a replacement - just cleaning!

In general, that's all - the engine itself will not suffer, the fuel system and filters may "be covered".

Actions after being noticed

I want to reassure you a little - if you noticed it immediately, for example, at a gas station, or after a couple of minutes of work. Then in 80% of cases nothing terrible will happen, gasoline simply may not be pumped into the system. However, you need to perform a few simple steps:

• We jam cars and don't start it again! This must be learned!


• We call a tow truck or a friend with a cable to be towed to the service station.


• At the service station, they remove the tank and wash it - it is necessary, it is necessary - to completely remove the gasoline.


• The entire fuel supply system is flushed, usually done with compressed air, again we remove the residues from the system.


• Replacement of fuel filters, fine and coarse cleaning.

If you are lucky, the fuel injection pump and injectors will remain intact. Then just bring normal diesel fuel, refuel and continue on the road. Of course, the work of cleaning the system will not be cheap, an acquaintance gave about 7,000 rubles, but it must be done, because if these steps are not followed, then expensive repairs fuel system diesel engine - guaranteed!

DIESEL IN GASOLINE

Reverse situations also happen. But when diesel fuel gets into a gasoline car, the situation changes dramatically. The density of gasoline is less than that of a diesel engine, therefore, already during refueling, all diesel fuel sinks to the bottom of the gas tank and strives to immediately get into fuel line... That is, almost immediately, drivers begin to feel the same knocks in the engine, loss of dynamics, and neighbors downstream also see clouds of black smoke erupting from the exhaust pipe.

The initial actions in case of an erroneous refueling are the same as described above: you must immediately drain the tank and fill the required fuel. However, getting diesel fuel into a gasoline engine for the most part does not threaten dire consequences. If the tank was empty and diesel fuel is the predominant substance in it, then the engine will stall almost instantly and will not have time to deteriorate. The compression ratio of the internal combustion engine and the spark from the spark plug are simply not enough to ignite the diesel.

If the car was half filled or more before entering the gas station, then the movement may work out. During the kilometers allotted to the car, filters and engine injectors will begin to clog on such a fuel mixture, and during long-term operation, the engine may be damaged, which will not be able to correctly synchronize the operation of the cylinders. A diesel engine contains a lot of paraffin, which clogs all lines and filter membranes, which happens at a double speed at negative temperatures. However, for this you need to have complete indifference to the symptoms that the car exhibits.

If it was possible to stop refueling a gasoline car at the very beginning, say, about five liters of diesel fuel were needed for a 50-liter tank, then most likely the car will not feel this. It is only important to remember that the tank must be filled to capacity with gasoline, preferably with an octane rating higher than the recommended one.

So a gas station mistake isn't catastrophic. If you realize it in time and act according to the correct algorithm, the situation can be corrected quite simply and without sacrifice. Or at least minimize the damage if you don't ignore the car signals.

Share your experiences and impressions if you find yourself in an awkward situation due to confused fuel.
