What Causes Gasoline to Leak from the Charcoal Canister?
1 Answers
If gasoline is leaking from the charcoal canister, it indicates that the canister has failed and must be replaced promptly. It is recommended to visit a professional auto repair shop or a 4S dealership to have the staff perform the replacement. More details are as follows: 1. Under normal circumstances, when the engine is turned off, the charcoal canister begins absorbing fuel vapors evaporating from the fuel tank, trapping them firmly within the micropores of the activated charcoal inside the canister to prevent the vapors from being released into the atmosphere. When the engine starts, the adsorbed fuel vapors in the canister are then delivered to the engine as fuel. 2. The charcoal canister not only reduces the vehicle's fuel consumption but also lowers its emissions. The charcoal canister is typically located between the engine and the fuel tank. It is part of the Evaporative Emission Control System (EVAP). 3. The charcoal canister is the most critical component of the Evaporative Emission Control System (EVAP). If the canister fails, the EVAP system cannot collect and store fuel vapors.
