What is the reason why the car smells of gasoline when driving?

1, aging of rubber pipe of carbon canister

The connection between the carbon canister and the throttle valve is made of rubber pipe, which may cause leakage once it ages.

2. The gasoline pipe leaks oil.

The leakage of gasoline pipeline generally occurs at the interface between pipelines. It can be judged by opening the engine compartment cover visually that if there is leakage at the interface, after a period of time, sludge formed by dust will be adsorbed on its surface.

Solution: Fasten the repair interface and replace the gasket.

3. After disassembling the gasoline pump.

Dismantling the gasoline pump needs to be completed in the car, and some oil leakage will inevitably occur during this process, and the replacement cycle of the gasoline pump is about 6,543,800 kilometers, so this situation is not common.

Solution: Go back to the repair shop to check the installation defects of the gasoline pump.

4. The smell of gasoline in the car is introduced into the car from the external environment.

Solution: the air conditioner adopts internal circulation mode, and the skylight is opened to exhaust air.
