Many car owners like to fill up the car's oil tank. Is it OK to fill up the car's oil tank? The answer is No. filling up the car's oil tank is harmful. Let's take a look at the harm of filling up the car's oil tank.
1. Oil leakage is easy to cause fire
The oil in the gas station is stored below the surface of the earth, and the temperature is low, especially in hot summer. Because of heat expansion and cold contraction, if the filling is too full, it may overflow from the vent. Not to mention causing waste, in case the spilled gasoline meets open fire (such as cigarette end), it is easy to cause fire or even explosion.
2. Plug the vent
Once the vent is blocked, negative pressure will be generated in the oil tank, resulting in poor oil supply or even no oil supply. The phenomenon that the engine can't start when the car is just filled with fuel, or the phenomenon that the car jumps up and down when driving at high speed, may be caused by the fuel tank being filled too full.
3. Hazard to carbon canister
The carbon canister is usually installed between the gasoline tank and the engine. As gasoline is a volatile liquid, the fuel tank is often full of vapor at room temperature. The function of fuel evaporative emission control system is to introduce vapor into combustion and prevent it from volatilizing into the atmosphere. This process plays an important role in the activated carbon storage device. If the fuel is too full, gasoline liquid instead of gasoline vapor will enter the carbon canister, which will cause damage to the carbon canister.
4. Gasoline volatilization is easy to cause cancer
The activated carbon canister is generally close to the air inlet of the external circulation. When the oil is too full, the canister will be saturated and the pressure will be too high, and the exhaust will be released. The air containing gasoline will enter the compartment, and the uncomfortable "gasoline smell" will surround you all the time. The composition of oil and gas has been proved to contain benzene and other carcinogens. Over a long period of time, it will inevitably cause harm to passengers.
