Can you fill a diesel car with gasoline? Can you fill a diesel car with gasoline

Diesel has a much higher ignition point than gasoline, which has a very low ignition point and does not need to compress air to burn. This is why the diesel engine and gasoline can still be started (but the gasoline contains less carbon, which is why the gasoline engine is weaker than the diesel engine), but the reason why the gasoline engine should be ignited by a spark plug is: in order to reduce the stroke of the cylinder (that is, the compression ratio), we all know that the longer the stroke of the cylinder, the engine will work very roughly, the vibration and noise will be very large, and when you make the stroke of the cylinder very long, the maximum speed of the engine will be much lower, and the speed will be low. The power is small.

Moreover, gasoline contains less carbon and does not require much air to burn, and gasoline is a flammable and explosive oil, which can be ignited by spark plugs to generate sparks. That's why gasoline engines can reach very high speeds. (Generally it can reach about 6000 rpm), so the compression ratio of the general gasoline engine is 1:

Left and right, some larger, are to improve fuel economy.

Diesel contains a lot more carbon than gasoline, which is why there is a lot of black smoke from trucks on the road. With a lot of carbon and a high ignition point, making the compression ratio a little larger is a double win. Generally 1:

Around 17. The reason why the spark plug is not used is because the ignition point is high, and it cannot be lit with a spark plug.

Finally: gasoline can be compressed and ignited, I don't believe you try to put gasoline into a diesel engine, but gasoline contains much less carbon than diesel, and it is very boring to drive. If the gasoline engine is ignited with compression, the compression ratio will be much larger than that with a spark plug, and the consequences will be:

The gasoline engine works roughly, rotates slowly, makes noise, has low power and other shortcomings!

So: a diesel car can still start with gasoline, but it doesn't have any strength.

A diesel car can be filled with a small amount of gasoline, but it is not good. The power of the car will deteriorate or the engine will shake. When too much gasoline is added, it will cause the vehicle to fail to start.

Diesel engine.

The pressure of the fuel injector is higher than that of a gasoline engine.

The pressure of the fuel injector is large, and after the diesel is added to the gasoline engine, the pressure of the fuel injector is not enough, resulting in insufficient atomization of the diesel and can only be partially atomized. As a result, part of the diesel directly enters the cylinder in the form of liquid, which is not fully combusted and is prone to carbon deposit.

And it can clog the injector. In this way, you will feel the engine weakness when driving, and it will be difficult to run.

Diesel has a lower ignition point in the spark plug.

Before ignition, the diesel fuel has reached the auto-ignition temperature and begins to burn violently, causing a problem called "detonation". A slight knock will not have much impact on the engine, but it is usually severe if the knock is caused by an engine problem, such as severe carbon deposits or poor heat dissipation.

Diesel engine features:

Diesel engines have high torque and outstanding load capacity, so many trucks and hard-core off-road vehicles will use diesel engines, and this series of advantages depends on the special ignition and combustion method of diesel engines.

The common ignition method is divided into ignition and compression ignition, while the diesel engine is the compression ignition, the so-called compression ignition is that after the diesel enters the combustion chamber, it mainly relies on the pressure of the piston in the cylinder to ignite the diesel, so it requires a large compression ratio.

In turn, it outputs more torque, so the diesel engine is relatively more powerful than the gasoline engine, and the instantaneous acceleration is faster.

Cars and buses with petrol, tractors and loaders with diesel.

1. Gasoline:

Gasoline is mainly used as a power fuel for transportation, such as passenger and freight vehicles, automobiles, ships, airplanes, etc. At the same time, rubber, paint, dyes, printing, pharmaceuticals, adhesives and other industrial gasoline are used as solvents.

2. Diesel:

Diesel is mainly used as the power of tractors, large automobiles, diesel locomotives and civil engineering, excavators, loaders, fishing boats, diesel generator sets and agricultural machinery, and is the fuel for diesel engines such as diesel vehicles and tractors.

Selection of diesel:

Diesel fuel is selected based on the temperature at which it is used. Diesel vehicles mainly use the last 5 grades of diesel, and when the temperature is above 4, 0 diesel is used to make oil; When the temperature is 4 --5, -10 diesel is selected.

When the temperature is -5 --14, -20 diesel is selected; When the temperature is -14 --29, -35 diesel is selected; If the grade of diesel is higher than the above temperature, the sock base of the fuel system in the engine may form wax, block the oil circuit, and affect the normal operation of the engine.
