If a gasoline car is filled with diesel, how far do you have to travel to find out that you have fil

The car is almost scrapped when the car is filled with the wrong fuel, what will happen if the car is refueled with the wrong fuel, how can we deal with this kind of thing, there are friends who like it and come to see it.

Difference Between Petrol and Diesel:

Gasoline has low carbon content, volatile, and a ignition point of 410°-430°, which is easy to mix with air and not easy to separate after mixing. The formation of fuel mixtures in gasoline vehicles usually takes place in the air intake duct outside the combustion chamber of the engine. The carbon content of diesel is higher, and it is not volatile, and its ignition point is lower at about 220°.

The formation of the fuel mixture for diesel vehicles is carried out in the combustion chamber of the engine. Diesel fuel is injected into the combustion chamber at high pressure and compressed to ignite, and then the diffusion combustion method is carried out while spraying.

Gasoline engine.

Differences from diesel engines:

Whether it is a gasoline engine or a diesel engine, they both belong to internal combustion engines. All of them are powered by burning fuel to generate thermal power to propel the piston to make a round-trip motion. The principle is basically the same, but the gasoline engine uses a spark plug.

ignition method; Diesel engines, on the other hand, use compression ignition due to their low ignition point. Rely on compressed air to raise the temperature to the ignition point of diesel, and then inject diesel, diesel spray and air mix while igniting and combustion.

What are the consequences of adding the wrong diesel, on the one hand, the gasoline engine.

The pressure of the fuel injector is smaller than that of the diesel engine, after the diesel is added to it, the diesel can not be completely atomized, and the combustion is not sufficient, so that the engine is weak, and the accelerator does not go, and the car will emit black smoke. There is also a situation where the ignition point of diesel fuel is low, and before the spark plug ignition, the diesel itself is already burning violently, resulting in abnormal pressure in the combustion chamber, which is commonly known as detonation, which will have great safety risks.

I think that when a gasoline car is added with diesel, you will find that you are adding the wrong oil, because the diesel has a low ignition point and does not burn enough in the gasoline engine, so the body is weak due to black smoke, and sometimes detonation in the combustion chamber will cause danger.

Gasoline and diesel work differently, gasoline car with diesel, it is best not to start, if you start can only go to the repair shop to clean the oil circuit.

If the gasoline car is filled with diesel, it must travel within 500 meters to find out that the wrong fuel has been added. Hope.

Can you still start this gasoline car with diesel?

The car was filled with the wrong diesel fuel and was immediately discovered.

If you add diesel, you will immediately find that because diesel is heavier than gasoline, it will be at the bottom of the fuel tank, and the fuel supply pipe is also at the bottom of the fuel tank, causing the car to fail to ignite or turn off after ignition.

ImpactIf the petrol car is filled with too much diesel by mistake, in many cases, the vehicle will not start. If it is started, because diesel has a lower ignition point than gasoline, it will burn as soon as it is compressed, and there is no need to go through the ignition system. The gasoline engine has an ignition system, and the igniter will directly ignite the diesel, causing engine knocking and easy damage to the engine.

Engine knock will cause the vehicle to shake and black smoke to emit from the exhaust pipe, and when the owner finds out about this situation, he cannot force the car to drive. It is important to stop to change the oil and clean the tank circuit, which may damage the entire oil system and engine.

If the wrong gasoline is added to a diesel car, it will first produce a knock, followed by the gasoline not reaching the combustion point inside the engine, causing the engine to stall. If you accidentally put the wrong gasoline, it will cause the engine to deflagrate, stall, and in serious cases, it will be easy to cause the blockage of the fuel injector because the lubrication of the fuel is not as good as that of diesel; In this case, the gasoline should be pumped out and cleaned to avoid further damage to the engine. Here's how to get the wrong gasoline on a diesel car:

1. It is necessary to pump all the oil in the fuel tank clean, and continuously clean the fuel tank and oil circuit with clean diesel. 2. Clean the oil pump and grease nozzle in time. If not cleaned in time, the gasoline will cause the internal parts of the oil pump to aggravate the wear and tear, resulting in serious damage to the oil pump.

3. The diesel filter must be replaced. The working principle of diesel engine and gasoline engine: The working principle of diesel compression ignition engine is to suck air into the cylinder for high-intensity compression to produce high temperature, and then spray into the cylinder in a mist manner through the high-pressure fuel injector to form a combustible mixed gas with air, so as to achieve automatic combustion and push the piston to do work, without the help of spark plugs for ignition.

The gasoline engine is sucked in air, compressed by the cylinder, and then injected into the atomized gasoline to form a combustible mixture, and then ignited by the spark plug, igniting the combustible mixture, and releasing a large amount of heat to push the piston to do work.

If diesel fuel is added to a gasoline car, black smoke or engine vibration will occur, and it will not start.

Gasoline and diesel are both refined from **, but their ignition points are different. Generally speaking, at atmospheric pressure, the ignition point of gasoline is 427; The ignition point of diesel fuel is 220.

Therefore, when designing the engine, the gasoline engine adopts the spark plug ignition method, and the diesel engine adopts the cylinder compression ignition method.

When the gasoline car mistakenly adds diesel, the engine will burn in advance and burst out when the ignition time is not reached, and the engine will have abnormal noise (knocking), and even damage the engine.

Gasoline vehicles with diesel treatment methods:

First of all, do not start the engine, pump out the diesel fuel in the fuel tank with a straw, add gasoline as soon as possible to the quantitative height of the fuel tank (keep the residual diesel content less than 8% or lower), so that it will not affect the engine, let it stand for a few minutes, so that the gasoline and residual diesel are fully mixed, start the engine, observe if there is any abnormality, and keep the car running normally.

The diesel car was refueled with gasoline and drove for three kilometers and found that it was related to the wrong gas. It is found that the diesel engine stops adding gasoline immediately after adding it, do not start the diesel engine, and then add diesel after the car completely discharges the gasoline, under normal circumstances, the diesel engine can still be started after adding gasoline by mistake, but it will be insufficient power, rough work, shaking, slow speed, loud noise, can not be used normally, and even cause damage to the diesel engine.

The principle of diesel and gasoline enginesBecause the working principle of diesel engine and gasoline engine is different, so the type of oil is not the same, the characteristics of diesel engine is high pressure, and the ignition point of diesel is low, so the diesel engine does not need to use spark plugs for ignition, on the contrary, the pressure of gasoline engine is relatively not so high, and the ignition point of gasoline is higher than that of diesel, so it needs to rely on spark plugs for ignition, if the diesel car adds the wrong gasoline.

First of all, there will be a detonation phenomenon, and then it will be caused by the gasoline in the diesel engine does not reach the ignition point and cause the flameout, the gasoline engine is to inhale the air by the cylinder to compress and then inject atomized gasoline to form a combustible mixture, and then the spark plug ignition ignites the combustible mixture and releases a lot of heat to push the piston to do work. Diesel cars with the wrong gasoline can cause the engine to deflagrate and then stall.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions!

Hello, if you fill too much this is the diesel filter element that will affect the diesel system. If it's just a fifty or sixty yuan stake, there's no problem with that. However, it is advisable to drain the gasoline and then refill and replace the diesel filter.

This is because it will not cause great damage to the diesel fuel supply system. If you continue driving, it may cause problems with the engine itself. This results in excessive detonation and high combustion temperatures.

Hello, I am your exclusive technician, attentive, careful, and dedicated to answering your car questions, and finding solutions to the corresponding problems and solutions for you! The relevant scheme is as follows: Hello, if you fill too much, this will affect the diesel filter element of the diesel system.

If it's just a fifty or sixty yuan stake, there's no problem with that. However, it is recommended to drain the gasoline and then refill and replace the diesel filter. This is because it will not cause great damage to the diesel fuel supply system.

If you continue driving, the spring potatoes can cause problems with the engine itself. This results in excessive detonation and high combustion temperatures. There is a faulty lamp.

If the diesel car runs 10 kilometers with the wrong gasoline, then the engine will be abnormal when idling, and there will be white smoke coming out of the exhaust pipe, if you continue to drive, it may cause engine damage and need to be overhauled, which is a big expense for the owner.

Are the consequences of gasoline refueled in a diesel car serious?

Diesel engines originally used compression ignition to process fuel, and the heat generated by the compression of air in the cylinder ignited the fuel, that is, the air compression will increase the temperature, and when the temperature is higher than the ignition point of the diesel, the diesel will burn. The ignition point of gasoline is much lower than that of diesel, and if you put gasoline into the diesel engine, it will cause the gasoline to burn prematurely, and the diesel will also be lit in advance. If this continues for a long time, the internal parts of the engine will be damaged.

The diesel engine runs for a long time, and the pressure and temperature of the engine will be very high, so the cylinder will produce a lot of impurities and carbon deposits. Engine oils are also more susceptible to oxidation, which can lead to the formation of gum. Therefore, the fuel of the diesel engine needs to be very good at high temperatures.

In the environment of the gasoline engine, it is easy to have low-temperature sludge, which requires the gasoline engine to have good low-temperature sludge dispersion. However, the diesel engine only has high temperature cleanliness, no low temperature sludge dispersion, if the gasoline is added to the diesel engine, the low temperature sludge produced by the gasoline can not be discharged, covering the engine, causing a certain impact on the use of the engine.

Solutions for adding gasoline to diesel cars:

1. If you find that the diesel car is filled with gasoline by mistake for the first time, do not start the engine casually. Call for help immediately, wait for the vehicle to be towed to the 4S shop, release all the oil in the fuel tank, and then clean the oil circuit to minimize the loss;

2. If you drive for a period of time and find out, you should also go to the 4S store for treatment as soon as you did, and replace the oil-water separator and diesel filter.

The problem of adding the wrong gasoline to diesel cars is still more serious, so it is best not to continue driving, turn off the engine and call the tow truck to the repair shop to clean up the gasoline, clean the fuel tank and oil circuit system, and change the fuel filter.

If you add some gasoline, then a lot of mixed diesel, it will make the power go down, and there is no big problem. If a large or all of the gasoline is filled, the diesel engine will not be able to ignite, and the gasoline needs to be pumped back to the diesel.

Gasoline differs from diesel in terms of carbon content: Diesel contains more carbon and is denser than gasoline, which means it is more resistant to the quality of diesel, in other words, it is more fuel-efficient than gasoline. In addition, the energy conversion ratio of a diesel engine with compression ignition is compared to a gasoline engine with a spark plug, which consumes almost half of the energy of a gasoline engine.

Gasoline and diesel oil are economically different: in addition to the carbon content and ignition method, diesel is better than gasoline engines because of its non-volatile and powerful properties. With the same displacement, the low torque of diesel vehicles will be stronger.
