Where is the activated charcoal canister located on the Mercedes-Benz E300?
1 Answers
The activated charcoal canister on the Mercedes-Benz E300 is located inside the right rear wheel hub. Function of the activated charcoal canister: The activated charcoal canister is a container filled with activated carbon, designed to adsorb gasoline vapors escaping from the fuel tank and carburetor when the engine is turned off. When the engine starts, the adsorbed gasoline is then blown out and burned. The activated charcoal canister is a crucial component in both the ignition and emission systems. During engine ignition, the gases from the activated charcoal canister are drawn into the engine's intake manifold via the canister purge valve, which is controlled by the fuel injection system's ECU to regulate its opening, closing, and the degree of absorption. The activated charcoal canister significantly reduces atmospheric pollution caused by exhaust emissions. Replacement interval for the activated charcoal canister: The replacement interval for the car's activated charcoal canister depends on the situation. If symptoms such as jerking, increased fuel consumption, or a gasoline odor occur and cannot be resolved through troubleshooting, it may be necessary to check if the canister needs replacement. Generally, the canister rarely requires replacement. For the first three to four years or 60,000 to 70,000 kilometers, there is usually no need for concern. Regular carbon deposit cleaning, using the correct gasoline grade, or occasionally using fuel additives can help ensure that the canister remains trouble-free.
