What happens when a petrol car is added to diesel? What happens to a car with diesel

Gasoline engines cannot add diesel, gasoline and diesel have different ignition points, and the combustion environment they adapt to is different. If the gasoline and diesel are mixed, after the gasoline is burned, it will die and the car will not be able to start, and the engine fault indicator will be on! Hope the above is helpful to you, thanks.

Although both gasoline and diesel engines are internal combustion engines, because of the low ignition point of diesel, it is around 220°; The ignition point of gasoline is as high as 410° to 430°, and the difference in ignition point also causes differences in the operation mode of the internal combustion engine.

<>First of all, the pressure of the fuel injector of the diesel engine is greater than that of the fuel injector of the gasoline engine, and after the diesel is added to the gasoline engine, the pressure of the fuel injector is not enough, resulting in insufficient diesel atomization and can only be partially atomized. As a result, some diesel fuel directly enters the cylinder in the form of liquid, which is not fully combusted, easy to accumulate carbon, and will clog the fuel injector. In this way, you will feel that the engine is weak when driving, and it will be meaty to run.

This is caused by inadequate combustion.

In addition, the diesel has a low ignition point, and the diesel has reached the auto-ignition temperature before the spark plug ignites, and it starts to burn violently! The disease caused by it is the legendary "detonation".

But if it's really as white as a river, don't worry. Don't start the car again, quickly find a 4S shop or car repair shop, put the wrong oil out, clean the oil circuit, fuel tank, and add the right fuel. However, it should be reminded that although brands such as BMW and other brands provide roadside assistance services, because this situation is caused by human reasons, the rescue is charged, and the cost depends on the distance.

The vehicle cannot be started. After the gasoline car is added to diesel, do not start, quickly clean the fuel tank, and the problem will be solved.

Gasoline vehicles are added to diesel, once the car is started, due to the insufficient pressure of the fuel injector, the diesel can only be partially atomized, directly in the form of liquid into the cylinder block, the combustion is not sufficient, easy to accumulate carbon, and will block the fuel injector.

After the gasoline engine is added to the diesel, before the spark plug is ignited, 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, causing damage to the engine of the vehicle, and serious will cause the engine to pull the cylinder.

The fuel tank volume indicated in the vehicle operation manual is less than the actual capacity of the fuel tank, because it is the safe capacity of the fuel tank, so the car fuel tank cannot exceed the safe capacity:

1. The volume marked on the fuel tank is not the actual maximum volume, but the maximum reasonable volume. The ordinary fuel tank can be charged with 10 15 more gasoline and diesel than the scalar amount.

2. Take a 60-liter fuel tank as an example, you can add up to 75 liters. Automobile manufacturers recommend a fuel tank capacity of 60 liters, taking into account the expansion coefficient of the refined oil. It is more reasonable to store less than 60 liters of oil, provide enough space for fuel expansion caused by temperature rise, and ensure the safety of the fuel tank during use.

3. The accuracy of fuel cannot be judged according to the rated capacity of the fuel tank. Automobile fuel tank is a container (the state management does not use it as a measuring instrument), not a measuring instrument, can not be used as a basis for judging whether the measurement is accurate, in accordance with the requirements of the relevant mandatory standards, the rated capacity of the automobile fuel tank should be controlled within 95 of the maximum safe capacity of the fuel tank. Second, you can't tell by the fuel gauge on the dashboard.

If the gasoline engine is filled with diesel, it will be easy to produce a large amount of carbon deposits due to incomplete combustion, and even the EFI system will be damaged as a result. Because diesel itself is less flammable than gasoline, the compression ratio of general diesel engines is lower than that of gasoline engines, so gasoline engines cannot use diesel.

What happens when diesel is added to a petrol car? Remember not to panic and see how the old driver solves it.

Not very good, a lot of faults.

Adding diesel to a gasoline car will have the following effects:1. The vehicle cannot be used: the exhaust pipe emits serious black smoke and cannot drive normally;

2. It will clog the fuel injector: because of the diesel engine.

Working in the way of compression ignition, the diesel cannot be completely atomized, resulting in fuel supply failure and blocking the fuel injector;

3. The engine will detonate: when the diesel enters the combustion chamber, the high-pressure mixture begins to burn violently, causing the pressure in the combustion chamber to be abnormal;

4. Serious shaking of driving: the engine will vibrate violently or accelerate poorly when driving.

How to dispose of gasoline vehicles with diesel fuelIf a petrol car accidentally fills up with diesel by mistake, don't start the vehicle with luck or curiosity. The mistaken diesel should be pumped out as soon as possible, and the fuel tank, fuel injectors, pipes, etc. should also be cleaned.

If the driver finds that the diesel fuel has been added by mistake after driving for a certain distance, he should stop the car immediately and turn off the ignition, tow the car to a professional 4S repair place, let the professional repair or maintenance, and do his best to minimize the loss.

Cars have gradually entered the average home, and some people will envy those who have a car. Wherever you go, it's easy to drive yourself. However, after having a car, there are many things to worry about, such as maintenance, repairs, etc.

There is nothing worrying in any way. So, what happens if a gasoline car is fueled by diesel? What to do with gasoline car and diesel?

Difference Between Petrol and Diesel.

If you want to know what happens to a petrol car with diesel, we can first understand the difference between petrol and diesel.

Diesel has a higher carbon content, density, and energy density as compared to gasoline. Gasoline has a low ignition point and is more volatile.

In a gasoline engine, a mixture of gasoline from the injector and an air mass from the throttle enters the cylinder and is ignited by a spark plug near the end of the compression stroke, producing the energy needed to provide the engine's power output, known as ignition.

The diesel engine uses the method of compressing the air gas to increase the temperature of the air body, so that the temperature of the air gas exceeds the spontaneous ignition point of the diesel fuel. At this time, diesel, diesel spray, and air are ejected out, and then ignite and burn on their own, which is called compression ignition. Therefore, diesel engines do not use ignition systems such as spark plugs.

What happens to a petrol car with diesel?

Gasoline cars are mistakenly loaded with diesel, and the car usually does not start. If activated, the igniter ignites the diesel fuel and detonates, causing damage to the engine. Its external manifestations are: the vehicle shakes, and the exhaust pipe emits black smoke.

And because diesel is denser than gasoline, diesel sinks to the bottom when it comes to rest, so even if you don't add much diesel, diesel will still enter the engine. If the vehicle is forcibly driven away at this time, the entire oil circuit system of the vehicle will be destroyed, and even the engine will be scrapped.

What to do with gasoline car and diesel?

It's not started yet. Most of the wrong refueling is self-refueling, and the type of fuel is not clear. If you notice a refueling error, don't panic and don't start the car. Instead, call a tow truck or find a nearby repair shop to push! In general, remove the fuel pump and put the fuel in the empty mailbox!

Replace the original gasoline filter! Then buy the right fuel and add it. At this time, it will not catch fire.

One more thing to do, and that is to take the fuel out of the pipeline. Because even if you don't start the car now, it doesn't mean the gas pump won't work! Many cars will have pre-made oil pressure when opening the door or remote control door!

The last thing is to take the gasoline out of the pipe. A lot of cars have this hole. If there is no oil pipe fitting in this hole, start the oil pump, pump in the gasoline, and push out the original diesel!

Connect the pipes and start the vehicle. It can take a little time to start, and you can fill it up once you get in the car! Remember to read the brand and label clearly to avoid unnecessary trouble!

It's already begun.

After filling up the gas, the car is already starting. If you realize that the wrong fuel has been filled, or if the above phenomenon has occurred, and you confirm that the wrong fuel has been filled, do not start the car again. You should call a professional service person for a quick repair, which will minimize the wear and tear on the car.

It should be reminded that insurance companies generally do not compensate for losses caused by the wrong fueling.

If the gasoline car is filled with diesel, because the diesel has a low ignition point, it can be compressed, and the gasoline is high. You can't compress it alone. The gasoline engine has a little source firefighter to light the diesel will detonate and damage the engine, so the lead source recommends that you clean the fuel tank immediately, the density of diesel is greater than that of gasoline, and the diesel will sink when it is stationary.

Gasoline will be on it. The first thing that enters the engine is diesel, which is very dangerous, so don't turn it on and wash it.

1. Carbon deposition, due to the high viscosity of diesel and the fuel injection pressure of the gasoline engine is lower than that of the diesel engine, the diesel and air in the cylinder cannot be fully mixed, and incomplete combustion will occur, resulting in a large amount of carbon deposition.

2. In the event of detonation, with the rise of the temperature in the cylinder, the hail hood and the spark plug are ignited, the high-pressure mixture reaches the spontaneous ignition temperature and begins to burn violently, resulting in abnormal pressure in the combustion chamber.

3. It is manifested as a large drop in power, accompanied by black smoke, and the car will shake after driving for a period of time, and even turn off.

If a gasoline car is filled with diesel, the engine will not start, and even the fuel supply system and engine will be destroyed. Therefore, it is important not to fill a gasoline car with diesel. Gasoline is different in nature from diesel. If diesel fuel is added, the engine will be destroyed, and the oil circuit must be cleaned.

The risk of adding diesel to a gasoline engine: First of all, the nozzle pressure of a gasoline engine is much smaller than that of a diesel engine. After adding diesel fuel to gasoline, because the nozzle pressure is insufficient, the diesel cannot be completely atomized and the combustion is not sufficient.

What you feel is engine weakness, and if you don't step on the accelerator, it will also seriously increase carbon deposits and clog the nozzles. Diesel, on the other hand, has a lower ignition point. Generally, gasoline engines are ignited by spark plugs.

In this way, before the spark plug ignites, the diesel fuel burns gradually and strongly, causing the combustion chamber pressure to be disturbed, which is commonly known as detonation.

How to respond:1. If you find that you have filled the wrong fuel (a whole tank of diesel fuel by mistake), remember not to order a chain-burning car to prevent the diesel from entering the oil circuit.

Then tow the car to a 4S shop or a car repair shop, clean the diesel, and then add gasoline. If you only add a little bit of diesel fuel (no more than 5-10% of the volume of the tank), if you find it early, in fact, it is not a big problem, just fill up with gasoline, it will not make any difference. 2.

In fact, the vast majority of friends who fill the wrong oil will not find out early, only after driving for a period of time (strong vibration or acceleration is the most obvious phenomenon) to realize the abnormality of the car, or when the fire has stopped. This situation is called immediate rescue. In addition to drying diesel fuel in the garage, it is also necessary to clean the oil circuit, replace the gasoline filter, and do a full inspection.
