Experts teach you how to deal with car oil spills[汽车维修知识]

Ms. Ma: A few days ago, I went to the 4S shop to do maintenance for the car and replaced the air filter and other parts. After maintenance, there will always be a strong smell of gasoline in the car, and there will be residual gasoline under the car after a long period of parking. I don't know how this kind of oil spill occurred? How to solve it?
ShanghaiThe massesCarWu Junhe, Technical Director of 4S Store in Tangdu, Shaanxi: Relatively speaking, car oil leakage is a common phenomenon, so car owners don't need to worry. In most cases, some car owners have overfilled the fuel, and the excess gasoline is not burned in the form of vapor. Because under normal circumstances, each car is equipped with an activated carbon canister on the right side of the engine compartment, which specifically adsorbs fuel vapor. When the engine is started, the activated carbon canister will absorb part of the fuel vapor, but the excess gasoline cannot be evaporated through the activated carbon canister. It is possible to flow from the air pipe. After a bumpy journey, the oil in the air pipe cannot be volatilized for a long time. At this time, you can smell a strong gasoline smell while sitting in the car. Therefore, for car owners, especially in summer, it is best not to refuel too much, otherwise serious situations will cause gasoline to overflow from the activated carbon tank tube, which is more troublesome.
In addition, the reason for the oil leakage is that when the general 4S shop changes the fuel filter to the car owner, because the fuel filter is under the car, it is inevitable that some pipes will not be inserted tightly during the replacement, which may cause oil leakage under the car. ; Or after refueling,tankThe oil pump seal ring inside is not installed properly, and the oil pipe is damaged. When the road conditions are not good, oil leakage will occur.
