What is a Car Charcoal Canister?

[VanAnastasia]

Charcoal canisters are typically installed between the fuel tank and the engine, serving as containers filled with activated charcoal. Below are some key points about automotive charcoal canisters: 1. Function: Positioned between the fuel tank and engine, it utilizes the adsorption capacity of internal activated charcoal to capture and store fuel vapors from the tank. 2. Working Principle: When the engine starts, the solenoid valve between the charcoal canister and intake manifold opens according to ECU instructions. The fuel vapors stored in the canister are then drawn into the combustion chamber along with air through the vacuum pressure in the intake manifold. This process not only reduces unnecessary emissions but also improves fuel efficiency.
