What Causes a Strong Gasoline Smell in Cars?
1 Answers
There are several reasons for a strong gasoline smell in cars: 1. Aging of the carbon canister rubber hoses; 2. Dirt accumulation on fuel injectors and throttle bodies due to long-term lack of cleaning, leading to incomplete gasoline combustion; 3. A dirty gasoline filter or loose/aged connecting hose joints; 4. A dirty or failed gasoline purification carbon canister; 5. Aging or loose fuel tank connecting hoses; 6. Poor vehicle sealing performance. Next to the gasoline filler hole, there is a vent for gasoline vapors. Its function is to allow gasoline vapors to escape when the fuel tank temperature rises. The vent maintains tank pressure above atmospheric pressure to prevent engine stalling.
