Everyone knows that there are two types of fuel oil, diesel and gasoline. On the Internet, it is also reported that the employees of gas stations mistake adding gasoline into diesel. What will happen if the gasoline car is added into diesel oil by mistake?
Gasoline and diesel are different fuel with different characteristics. Besides high energy density, diesel oil has another difference with gasoline, which is volatile. The ignition point of diesel is lower than that of gasoline, but it is not easy to ignite because of its poor volatility. Because diesel is not easy to volatilize in the air, diesel is better than gasoline in terms of safety. The main difference between diesel engine and gasoline engine is ignition system and fuel supply system. Diesel is ignited by air compression and exothermic, so diesel engine has no ignition system, but diesel engine depends on fuel supply system, and it can not atomize diesel fuel sufficiently and inject fuel quickly without enough injection pressure. The pressure of the injection nozzle of the in cylinder gasoline injection vehicle 250bar is quite high, but the injection pressure of diesel engine is light and loose 2000bar.
Diesel fuel will cause poor fuel atomization. For some vehicles with low compression ratio and low injection pressure, diesel fuel will not be ignited at all. Diesel without complete atomization will affect the ignition performance of spark plug. Therefore, for gasoline vehicles with general performance, diesel fuel will either be turned off or can not move at all.
Although the problem of adding diesel fuel to gasoline car is very attractive, you should know that the diameter of diesel gun is bigger before this problem occurs. If your car has no design defects, the biggest problem is how to insert the oil gun into the tank of the gasoline car?
Diesel car gasoline is called terror. The problem of gasoline car adding diesel is only concerned by people out of fear and curiosity. However, it is necessary to pay attention to the problem. If you don't pay attention to filling up the diesel car with gasoline, you really need to prepare for a overhaul.
In the compression ratio and injection mode of diesel engine, gasoline may ignite and cause severe knock before the piston reaches the top stop. The oil pump of diesel engine is special, it is said that diesel oil plays a role in lubrication. But adding gasoline in diesel vehicle will cause abnormal loss of oil pump, and even damage of high pressure common rail system. Diesel cars are very popular in Europe, and there are many incidents of adding gasoline to diesel cars. If they are found earlier, do not start the engine. It is OK to put out the gasoline in the tank. There are even rescue vehicles specially used for pumping oil in Europe.
In a word, in order to distinguish between diesel and gasoline, not only the caliber of the fuel gun is different but also the color is different. The fuel tank mouth of the gasoline car is smaller, so it is difficult to add diesel oil. However, the possibility of misfueling the diesel engine is even greater, and the consequences are more serious.
