What happens when a diesel car is filled with gasoline?

Hello, if the diesel car is mistakenly added to the gasoline is not opened, once the gasoline is added, do not start the car, so as not to cause secondary damage to the car engine. Generally, Sinopec gas stations have convenient services, at this time you can ask the gas station staff for help, ask them to help push your car away from the refueling area, and then contact the repair shop, let the repair shop help you pump all the mixed oil clean, and refill the diesel fuel. If there is a lot of oil mixture, you can convert the oil mixture into the repair fee for the repair shop to help you repair, which can help you save a repair money.

Hope mine can help you, hope, thank you!

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.

In addition, if the engine is damaged due to the misuse of fuel, you will not be able to obtain the manufacturer's warranty, and you will need to bear the loss.

Nothing serious. Diesel cars are afraid of freezing oil in winter, so they deliberately add some gasoline to it. You add a bit too much gas, though.

Just drop a little gasoline. If you can't put it. Add more diesel fuel to it.

Something about steaming. You can also open the fuel cap. There is no problem with opening.

I'm afraid that the explosive power may be smaller.

This problem is big, you are not adding the wrong label, but bold, you need to clean the oil circuit thoroughly, otherwise it will damage the engine, because the working principle of gasoline and diesel engines is not the same.

Gasoline vehicles and diesel will cause the engine to detonate, which will bring irreversible damage to the engine, and even pull the cylinder in serious cases. If the diesel is added to the gasoline engine, the pressure of the diesel engine injector is greater than that of the gasoline engine injector, after the diesel is added to the gasoline engine, due to the insufficient pressure of the injector, the diesel cannot be completely atomized, and can only be partially atomized, and the consequence is that part of the diesel directly enters the cylinder in the form of liquid, the combustion is not sufficient, and the fuel injector will be blocked.

The ignition point of diesel fuel is low, after the diesel enters the cylinder, before the spark plug ignites, the high-pressure mixture reaches the auto-ignition temperature and begins to burn violently, causing the pressure in the combustion chamber to be abnormal.

The reason why gasoline cars can't be filled with diesel.

From the point of view of ignition mode, although diesel engine and gasoline engine are both internal combustion engines, but the ignition methods of the two are completely different, the spontaneous ignition point of diesel is low, about 220 degrees, and the spontaneous ignition point of gasoline is higher, which can reach between 410 degrees and 430 degrees, and the diesel engine is a compression ignition method;

There is no need for additional spark plugs to ignite the fire, and the temperature can be raised to the ignition point of diesel fuel with compressed air alone, and then diesel fuel can be injected to burn on its own. However, gasoline engines are not, due to the high spontaneous ignition point, the fuel cannot be ignited only by engine cylinder compression, and the electric spark from the spark plug is needed to ignite before combustion. Therefore, gasoline cars cannot be filled with diesel.

First of all, the pressure of the diesel engine fuel injector is greater than the pressure of the fuel injector of the gasoline engine, after the diesel is added to the gasoline engine, due to the insufficient pressure of the fuel injector, the diesel can not be completely atomized, and can only be partially atomized, the consequence is that part of the diesel directly enters the cylinder in the form of liquid, the combustion is not sufficient, it is easy to accumulate carbon, and it will block the fuel injector, which is one of them.

The ignition point of diesel is low, and the ordinary gasoline engine is ignited by the spark plug, and after the gasoline engine is added to the diesel, before the spark plug ignites, the high-pressure mixture reaches the spontaneous ignition temperature and begins to burn violently, resulting in abnormal pressure in the combustion chamber, commonly known as detonation, which is the second.

Answer 1: The engine becomes weak, the accelerator pedal also loses its effect, and even the carbon deposition increases seriously, and the fuel injector is blocked; 2. There are phenomena such as shaking the car, black smoke from the exhaust and even failure to start the engine.

The solution to adding diesel to gasoline vehicles is: 1. Do not start the engine; 2. Pump out the diesel fuel in the fuel tank with a straw; 3. Clean the fuel tank, fuel injector, etc.; 4. Add gasoline to the quantitative height of the fuel tank as soon as possible.

It was supposed that the pipe also had diesel, and then it was not cleaned.

The working principle of the two machines is not the same, the gasoline engine is ignited, the diesel car is compression-ignited, gasoline is easier to burn, diesel is not easy to burn, gasoline is thinner, diesel is thicker, there is a lot of trouble, in a word, the gasoline engine is added with diesel, and the machine is finished after working for a long time.

What to do if you fill the wrong car with the wrong fuel.

Early detection of engine malfunctions.

If the wrong fuel is detected early, the damage can be reduced. Even if gasoline is added to diesel cars and diesel is added to automobiles, if you can detect and deal with it earlier, you don't have to worry about it. The symptoms caused by the wrong oil are:

When gasoline mixed with diesel is supplied, the engine will be weakened, acceleration will be poor, and idle malfunction will gradually occur. In addition, because of the exhaust of black smoke and odors, drivers can easily detect abnormalities. If the fuel is only diesel, thick black smoke will come out of the exhaust, and the engine will be obviously out of order and will not start.

So, what about diesel engines when gasoline is added? At first the engine was running, but it immediately failed. After driving for a while, the engine noise became louder, the idle speed became unstable, and white smoke began to emit from the exhaust pipe.

At about this point, when the engine is less damaged, it is found that if the fuel is changed immediately, the engine can still be used without special adjustments.

Change the fuel immediately.

Whether it is a petrol or diesel vehicle, the fuel must be replaced immediately. If you drive for a while and find out, don't drive any further and refuel at the nearest gas station. When refueling, be clear about the type of diesel or gasoline.

In addition, it is important to specify the type of fuel at the fuel filler, so it is important to make sure that you do not make a mistake when refueling. In response to this problem, recent improvements have been made by gas stations and car dealers, such as marking the design of the fuel filler and fuel filler, all of which are changed for fear of filling the wrong fuel.

After adding gasoline, it will affect the performance and service life of the engine. The working condition of the gasoline engine is different from that of the diesel engine, the gasoline vehicle is a mixture of oil and gas through the spark plug to produce spark ignition, the gasoline ignition point is low, the working noise is small, and the clearance of various combinations is small; The diesel vehicle compresses the diesel through the fuel injection pump to produce high-pressure diesel, which is rough and has a large gap.

The ignition point of gasoline is much lower than that of diesel, and putting gasoline into the diesel machine will cause the fuel to burn in advance, making the diesel engine work abnormally, and the parts of the entire engine will be damaged for a long time, resulting in great losses. Diesel engine vehicles often drive on the road, the vehicle runs for a long time, the engine temperature and pressure are high, the cylinder produces more soot and carbon deposits, and the engine oil is also easy to oxidize to produce gum, so diesel engine oil requires good high temperature cleanliness.

Therefore, the requirements for engine oil are different from diesel vehicles, and the requirements for gasoline engine oil are thinner and have good fluidity; The working pressure of diesel engine oil is high, the environment is poor, and the carbon deposit is generated, which requires strong cleaning ability and large gap. When gasoline is added, the engine will have abnormal idle speed, white gas from the exhaust pipe, and long-term use of gasoline oil may lead to the scrapping of the diesel engine.

Diesel cars with gasoline will cause the engine to idle abnormally, and the exhaust pipe will release white gas. Long-term use can lead to the scrapping of the engine.

The treatment of diesel fuel is compression ignition. The fuel is ignited by the heat generated by the compression of the air in the cylinder, that is, the compression of the air will heat up, and when the temperature of the compressed air gas is higher than the ignition point of the diesel, the diesel will burn. However, the ignition point of gasoline is much lower than that of diesel.

Putting gasoline into diesel may cause the fuel to burn prematurely, making the diesel engine work abnormally. Over time, it will damage the entire engine parts, causing a lot of damage.

Diesel engines are often driven on highways. When the vehicle is driven for a long time, the temperature and pressure of the engine are high, and more soot and carbon deposits are generated in the cylinder. Motor oil is also susceptible to oxidation to form colloids. Therefore, diesel engine oil needs good high-temperature cleanliness.

However, gasoline is prone to produce low-temperature sludge in the engine environment, so gasoline engine oil is required to have good low-temperature sludge dispersion. If the gasoline produces a large amount of low-temperature sludge after combustion in the diesel engine environment, and the oil of the diesel engine only has good high-temperature cleanliness and does not have low-temperature sludge dispersion, the resulting sludge cannot be discharged, which will cover the engine and affect the use of the engine.
