Where is the Car's Charcoal Canister Located?

[Geraldine]

Automobile charcoal canister is located between the car engine and the fuel tank. Here are the relevant details about the charcoal canister: 1. Function: When the engine is running and the solenoid valve is activated, the engine draws fuel vapor from the fuel tank and the vapor adsorbed by the active material into the intake manifold. When the engine is not running or the solenoid valve is not activated, the vapor from the fuel tank enters the charcoal canister and is absorbed by the active material. 2. Working Principle: When the engine is running and reaches medium to high speed, the solenoid valve is energized, opening the pipeline. The vacuum in the engine's intake manifold then draws the combustible gas from the charcoal canister into the cylinders to participate in combustion. Simultaneously, external air enters the charcoal canister through the breathing hole, flows through the internal absorption layer, mixes with the fuel to form combustible gas, and then flows into the engine's intake pipe. During this process, the activated charcoal in the canister is gradually restored due to the suction effect of the engine.
