What Causes the Smell of Gasoline When Starting the Car?

[DakotaLee]

When there is a smell of gasoline after starting the car, the main reasons are as follows: 1. Engine cylinder issue: The cylinder can absorb gasoline, leading to carbon buildup. If carbon deposits are not cleaned for a long time, it will increase fuel consumption and cause the car to emit a gasoline smell. Therefore, it is essential to clean the carbon deposits promptly. 2. Dirty throttle body: The throttle body is prone to dirt, and residues can accumulate on it during driving, causing hesitation when accelerating. It is necessary to clean the throttle body in time. 3. Aging carbon canister: An aging carbon canister will inevitably lead to gasoline leakage. If the gasoline flows into the engine compartment, it can enter the car through the air conditioning system. If the carbon canister is aging, it should be inspected and repaired at a service center promptly.
