EVAP Canister

EVAP Canister:




The EVAP canister, tilled with charcoal pellets, stores the fuel vapors from the fuel tank. Vacuum is pulled from the fuel tank through the Vapor pipe (2). Fresh air (3) is mixed with the vapors and pulled to the intake manifold from the canister through the purge line (1). The engine vacuum purges the EVAP canister during normal driving.
