What Causes the Smell of Gasoline When Starting the Vehicle?

[MacEverett]

Vehicle starting with a gasoline smell is caused by: 1. Insufficient air intake in the throttle; 2. Problems with the carbon canister or carbon canister solenoid valve, resulting in an overly rich air-fuel mixture; 3. Excessive carbon buildup inside the engine, leading to poor atomization of the mixture; 4. Leakage in the fuel injector. The solution is to recommend immediate repair at a professional maintenance shop. In winter, the conditions for gasoline atomization are poor, especially for vehicles with carburetors, which are generally difficult to start and cannot immediately transition to normal operation after starting. It is recommended to clean and unclog all oil and air passages during winter maintenance, check the working conditions of the throttle, choke, accelerator pump, and vacuum pump, and adjust them to the optimal state.
