[McRose]

Symptoms of a faulty car charcoal canister: 1. Abnormal noises while driving; 2. Jerking during rapid acceleration; 3. Noticeable gasoline odor; 4. Weak acceleration; 5. Fluctuating engine idle speed; 6. Engine stalling; 7. Difficulty starting, affecting normal engine operation. The main function of the charcoal canister: It adsorbs and filters gasoline vapors inside the fuel tank, controlling the entry of fuel vapors into the engine via an electromagnetic valve to participate in combustion, thereby reducing fuel consumption and preventing excessive fuel tank pressure. Methods for cleaning a car charcoal canister include: 1. Washing with gasoline; 2. Scrubbing with wood ash; 3. Applying dough paste, letting it dry, and then peeling it off; 4. For heavy oil stains, using thinner and turpentine to wipe, then washing with detergent after the oil stains dissolve.
