Recently, in a gas station in Chongqing, because the tanker was unloading oil, the gas station staff connected the wrong pipe and unloaded the whole vehicle diesel into the gasoline storage tank, and then more than 200 vehicles added this mixed oil. According to many car owners, after driving out of the gas station, they felt that the car body was shaking seriously. After driving for a certain distance, the car broke down. The incident has been properly handled, and the gas station has contacted all involved car owners to reach a maintenance compensation agreement.
We have studied the working principles of gasoline engines and diesel engines in junior high school physics textbooks. A gasoline engine is ignited directly by a spark plug, while a diesel engine needs a mixture of diesel oil and air compressed by a piston to ignite. The ignition mode of gasoline engine and diesel engine is different, if the wrong oil is added, the engine will be seriously damaged. Maybe some friends will ask, why do gasoline engines need to be ignited by spark plugs, while diesel engines need to be ignited by compression ignition?
Your asking shows that you didn't listen carefully in junior high school physics class. First of all, why do gasoline engines use spark plugs to ignite? There is a simple reason. Because the ignition point of gasoline is very low, a little spark will cause combustion, so it is simpler and more direct for gasoline engines to ignite with spark plugs, while the ignition point of diesel is much higher than that of gasoline. If the spark plug is used for ignition, the diesel in the cylinder will not ignite and the engine will not work.
Because the ignition point of diesel oil is much higher, the ignition mode of diesel engine can only rely on compression heating to burn the mixture of diesel oil and air. Because the ignition points of the two fuels are different, if diesel is added to the gasoline engine, the engine will stall, or after some gasoline is burned, the diesel mixed in it will not burn, resulting in the spark plug being wrapped, and then the engine will stall and fail to work. Therefore, after the gasoline vehicle is mixed with diesel, the first thing to do is to clean the fuel tank, oil circuit, carburetor, fuel nozzle and replace the spark plug.
Compared with gasoline engine, diesel engine mixed with diesel oil will lead to engine flameout and spark plug damage, and diesel engine mixed with gasoline is even more annoying, because the ignition point of gasoline is lower than diesel oil. If diesel and gasoline are mixed together, it will directly lead to cylinder explosion, and serious engines will be scrapped directly.
Treatment steps of gasoline vehicles mixed with diesel oil
First, clear responsibilities.
When you find that your gasoline car shook badly after it was filled with oil, and then it stopped, it is likely that you filled it with the wrong oil. Contact the gas station as soon as possible and keep relevant evidence, such as invoices issued by the gas station.
Second, send it to the repair shop for timely maintenance.
When the vehicle has been turned off, contact the repair shop to send a trailer to the repair shop, or contact the gas station in advance. If the gas station is willing to bear the maintenance cost and appoint a repair shop for maintenance, it can actively negotiate with the gas station.
Third, retain evidence to negotiate claims.
If after contacting the gas station, the gas station refuses to pay compensation and shirks its responsibility, then you can defend your rights in several ways. First, call the police, and then file a case through the police to provide more powerful evidence for later prosecution of gas stations. Second, dial 123 15, which will be handled by the market supervision and management department, on the one hand, to prepare for more evidence collection. If negotiation fails, we can only bring a lawsuit to the court.
When the gasoline vehicle is mixed with diesel oil, the engine will start to shake, then turn off, the engine will not work, the spark plug will be damaged, and the cylinder block will be damaged seriously. The maintenance method is to clean the fuel tank, oil circuit, carburetor, oil nozzle and cylinder, and replace the spark plug.
