Why is there gasoline in the carbon canister?

[OCharlie]

Carbon canister contains gasoline because the pipeline connected to the solenoid valve at one end of the carbon canister is disconnected, and the car is started and slowly accelerated. A plastic film is placed at the solenoid valve pipe opening to check for suction, or there is a defect in the fuel tank design of the car. No measures were taken to prevent overfilling during the design, which eventually led to liquid gasoline entering the carbon canister through the conduit. Here is more information about the carbon canister: 1. The role of the carbon canister: The carbon canister is part of the vehicle's gasoline evaporation control system and is installed between the fuel tank and the engine. The carbon canister's function is to introduce vapor into the engine cylinder for combustion and prevent it from volatilizing into the atmosphere. 2. Symptoms of carbon canister failure: When the carbon canister fails, the vehicle may exhibit symptoms such as abnormal noise while driving, jerking when stepping on the accelerator, severe fuel odor inside the car, unstable engine idle, lack of power during acceleration, engine prone to stalling, and difficulty starting the car.
