Why can t diesel engines burn gasoline, and can diesel engines burn gasoline?

Reasons why diesel engines can't burn gasoline: Diesel engines work differently from gasoline engines.

Both diesel and gasoline engines are four-strokes: suction stroke, compression stroke, power stroke, exhaust stroke.

Differences: The diesel engine sucks in air, and the compressed air is also air, and the diesel enters the cylinder through the fuel injector, which does not need to be ignited, and is compression-ignition.

The gasoline engine inhales a mixture of air and gasoline, and compresses a mixture of air and gasoline.

So: because the two principles are different, diesel engines cannot burn gasoline.

Because the working performance of the engine is different, the diesel engine relies on the compression of diesel to produce heat energy, while the gasoline engine relies on combustion to generate heat energy!

Due to the high compression ratio of the diesel engine, adding gasoline will explode early, although it can be started, but there will be a sound of knocking the cylinder, and the work is weak.

The compression ratio of the gasoline engine is 4 6. The compression ratio of the diesel engine is 15 18.

If gasoline is added to the diesel engine, there is no doubt that it will be fine to ignite and burn, but because the compression ratio is much higher, there will be a deflagration in the cylinder, which will cause great damage to the engine.

It is not a problem with the structure of the machine, but the characteristics of gasoline and diesel. The structure of the machine was also designed according to the characteristics of the fuel.

The gasoline engine is ignited, and the diesel engine is compression ignition.

I cannot.

Although the diesel engine and the gasoline engine are four-stroke: suction stroke, compression stroke, power stroke, exhaust stroke, but the diesel engine misuses gasoline will never work, but if the gasoline engine misuses diesel, the gasoline engine can work, but the power is poor, and the exhaust pipe behind the sudden discharge and black smoke is discharged, and the engine is greatly damaged after running for a long time.

A small amount of gasoline is mixed into the diesel without affecting the operation of the engine. and can fight diesel freezing in winter. That is, it can enhance the low-temperature fluidity of diesel. However, if it is incorporated too much, it will make it difficult to start.

My personal experience: one winter because the bus added No. 0 diesel, the next morning the weather turned cold, just out of the city, the car broke down, with the fire for a while, okay. After walking a few kilometers, I just got to a gas station and broke down again.

I'm in a hurry, I just added a tank of fuel, to say the least, it takes 60 liters, and a car of people still have to go to work, what should I do? I opened the tank cap, got waxy diesel oil out of it, and baked the tank as I thought about it. I had an idea, the freezing point of gasoline is more than -70 °, why not try it?

All right. This tank of oil ran smoothly, and there was nothing wrong with the cold weather. Starting the car in the morning is also normal.

No, the gasoline engine is ignited, and the diesel engine is compression-ignited Their ignition points are not the same, and the compression ratio of the gasoline engine and the diesel engine is not the same.

The diesel engine has one less ignition system than the gasoline engine, and the working principle of the diesel engine is "pressing", the fuel injector injects the diesel into the cylinder, and the piston compresses the diesel to do work after combustion. The working principle of the gasoline engine is to "ignite", suck in the gasoline combustible mixture from the air intake, and the spark plug ignites the gasoline and does the work.

If the diesel engine misuses gasoline, it will never work, but if the gasoline engine misuses diesel, the gasoline engine can work, but the power is poor! The rear exhaust pipe suddenly discharges guns and emits black smoke, which is extremely damaging to the engine after running for a long time!

No, the ignition point is different, and the structure and working principle of the engine are also different.

No, or the engine will break. Make no mistake.

Can burn, as long as you're not afraid of the engine being scrapped, burn it as much as you like.

Most of the engine oil burned in diesel vehicles is caused by the piston ring being trapped by carbon deposits. Relying on the addition of high-viscosity engine oil to continue life is only an expedient measure to cure the change. When the oil enters the combustion chamber to participate in combustion, more carbon deposits will be formed, which in turn will lead to the aggravation of the burning of engine oil, forming a vicious circle.

In the long run, it will cause strain on the slag hand wall, or even burst the cylinder, and finally the engine can only be disassembled for overhaul.

Four reasons for burning engine oil.

A ...If you don't clean the oil circuit for a long time or don't do effective oil circuit cleaning, detergents are used at will, and using detergents and effective detergents are two different things;

IIThe antifreeze replacement cycle is too long or not changed at all;

IIIThe oil change interval is too long;

IVLong-term or often short-distance driving.

The above four points of the vehicle that burns engine oil must be occupied by one or all four points.

How the piston rings are stuck.

The principle of piston ring stagnation should start from the oil circuit, the oil temperature is 110 degrees, and the high temperature caused by the long-term unclean oil circuit makes the oil at a temperature of 120 degrees or higher for a long time, so that the oil will be exhausted in advance, the small hole of the oil ring is very small, and the oil inside will be dried and scabbed for a long time. It becomes 1000 kilometers or even hundreds of kilometers of a liter of oil loss. Therefore, in order to solve the problem, we must start from the root oil circuit, which is the way to remove the root.

The solution to burning the oil.

In the habitual thinking of car enthusiasts, they always think that burning engine oil should be overhauled, so that they not only have to bear high maintenance costs, but also bear the unpredictable risks and depreciation losses brought about by the overhaul. Destroy the airtightness and precision of the engine. And there is a possibility that the engine oil will burn again after tens of thousands of kilometers, so overhauling the engine is not sustainable.

Now the no-dismantling technology has been very mature and gradually accepted by the majority of car owners. In particular, the non-destructive repair products containing PNF patented technology have completely gotten rid of the technical shackles of the operation of the auto repair shop, and the owner can operate it himself without removing a screw, and the piston ring is repaired and released during driving, and the effect is remarkable.

Mercedes-Benz GL350 diesel engine burns oil for the following reasons, and it is easy to check. When this engine is inspected, because the injector is not easy to disassemble, it takes two or three hours to disassemble the injector, which is more troublesome, so the repair shop is not willing to help us check the injector. Combined with the characteristics of diesel vehicles themselves, the probability of cylinder wall wear and cylinder barrel loss of circle in diesel vehicles is not particularly large, so the very troublesome links can be put to the final inspection.

Test the oil-gas separator with a negative pressure meter first, and replace it if there is a problem with the oil-air separator. When the car burns oil, the piston ring is 100% stuck, and usually the number of kilometers that burns oil in this car is 150,000 kilometers. Some riders generally change the engine oil around 10,000 kilometers, if the road conditions are better if they often drive, there is no problem, but it should be noted that one link is the diesel filter element, diesel is particularly easy to produce water absorption, and there will be excess water production after a long time in the fuel tank, and the role of the diesel filter element is very obvious, which is to filter out a part of the water in the diesel.

If this moisture is carried into the combustion chamber to participate in combustion, the engine will detonate and misfire. Detonation misfire will cause the temperature of the diesel engine to rise instantaneously, diesel contains a large amount of gum and moisture, the burning ash is more than normal diesel into the oil, the oil sludge in the oil will be more, coupled with the problem of 10,000 kilometers of oil change superimposed high temperature, it will lead to the diesel engine's piston pants rubber ring oil ring small hole scraping oil is not clean and blocked, suddenly there is oil burning.

Many diesel cars do not have a slow process of burning engine oil like gasoline cars, and it is very likely that the diesel car was okay with the last maintenance, and this maintenance will have problems in an instant. Because the combustion condition of diesel vehicles is lower than that of gasoline vehicles, there is almost no problem with the valve oil seal before 200,000 kilometers, so there is no need to consider the problem of valve oil seal.

The above is about the diesel car should pay attention to the inspection of the first thing, it is very easy to solve the problem of piston rings, use the oil and fuel models of PNF technology at the same time, superimpose the number of repairs once, drive more and drive more, whether it is a gasoline car or a diesel car, it can solve the problem of burning the piston ring caused by blockage and stagnation.

The mixture is difficult to form, and the combustion is not complete. Improvement: Promote the formation of gas mixtures. More air is supplied.

2.The work is rough and slippery, and the combustion noise is large. Shortening the ignition delay time i, reducing the amount of fuel injected during the lag period, and inhibiting the formation of the mixture at this stage can reduce the combustion noise, but it contradicts the improvement of dynamics.

3.Black smoke from the exhaust. The main measures to reduce black smoke are as follows: (1) Increase the excess air coefficient. However, it contradicts improving the power of diesel engines. (2) Improve the formation of gas mixture. Contradicts improving the softness of the work of diesel engines.

4.The exhaust emits blue smoke and white smoke.

A diesel four-cylinder engine is an internal combustion engine that works by compressing air to spontaneously ignite diesel fuel, which generates energy to drive the engine to work. If you want to prevent spontaneous combustion of diesel four-cylinder engines, you need to pay attention to the following points:1

Ensure good fuel quality: Use high-quality diesel fuel and avoid using low-quality fuel that can cause spontaneous combustion. 2.

Control the amount of fuel injection: reasonably control the amount of fuel injection and avoid excessive fuel injection, so as not to cause spontaneous combustion. 3.

Keep the engine clean: Clean the engine regularly to keep the inside of the engine clean to avoid carbon deposits and oil build-up, which can cause spontaneous combustion. 4.

Regularly inspect the engine: regularly check the parameters of the engine, such as fuel pressure, injector status, etc., and timely find and repair the problem to avoid spontaneous combustion. In short, in order to prevent spontaneous combustion of diesel four-cylinder engines, it is necessary to pay attention to fuel quality, fuel injection, engine cleanliness and regular inspections to maintain the normal operation of the engine.

After the diesel is heated, the power of the diesel engine will not be pro, hello! The high temperature of diesel fuel can cause the wear of the pump and injector of the fuel injection belt to intensify, and the temperature in the cylinder will rise, which will affect the engine power. For those advanced engines, the impact is significant, such as single pump engines and EFI engines.

Generally, the electronically controlled engine is more sensitive to the temperature of diesel, and the oil return volume is large and the oil heats up quickly. The temperature of diesel is high, and the power drop is more serious. Hope it helps!
