What Causes the Smell of Gasoline After a Cold Start?

[LeRemington]

The reasons for smelling gasoline inside the car after a cold start are: 1. Insufficient air intake in the throttle; 2. Problems with the carbon canister or carbon canister solenoid valve; 3. Excessive carbon buildup inside the engine, leading to poor atomization of the air-fuel mixture; 4. Leakage in the fuel injector; 5. Low external temperature causing incomplete combustion of the mixture, which is directly discharged through the exhaust pipe; 6. The solenoid valve remains closed; 7. Aging of the carbon canister rubber hose. The methods to address the smell of gasoline after a cold start are: 1. Replace the throttle; 2. Replace the carbon canister or carbon canister solenoid valve; 3. Clean the engine interior; 4. Replace the fuel injector; 5. Open the solenoid valve; 6. Replace the carbon canister rubber hose.
