What Causes a Strong Gasoline Smell After Starting the Car?

[ElisaDella]

Car starting with a strong gasoline smell is caused by a damaged carbon canister, which can be resolved by replacing the new carbon canister; if the engine has an oil leakage issue, the leaked oil dripping onto the exhaust pipe can also result in a gasoline smell inside the car, requiring the replacement of the sealing gasket to fix the oil leakage problem. The carbon canister is part of the gasoline evaporation control system, which was introduced to prevent fuel vapors from escaping into the atmosphere after the engine stops running. The carbon canister installed in the car is actually an assembly, with its casing mostly made of plastic, filled internally with activated carbon particles that can adsorb vapors, and equipped with a purge control valve at the top to regulate the amount of gasoline vapor and air entering the intake manifold, along with a filter screen to purify gasoline vapors.
