I Emission Control System OPERATION Fuel vapors from the sealed fuel tank are led into the carbon canister. © © The canister is filled with activated charcoals to absorb the fuel vapors when the engine is at rest or at idling. See Figure EC-56. 1 Fuel tank 6 2 Fuel filler cap with 7 vacuum relief valve 8 3 Liquid/vapor separator 9 4 Vapor vent line 10 5 Vacuum signal line 11 Canister purge line Throttle valve Engine Carbon canister Activated carbon Screen 12 Filter 13 Purge control valve 14 Diaphragm spring 15 Diaphragm 16 Fixed orifice EC368 Fig. EC-56 Evaporative emission control system (Fuel vapor flow when engine is at rest or at idle.) As the throttle valve opens and car speed increases, vacuum pressure in the vacuum signal line forces the purge control valve to open, and admits an orifice to intake manifold and fuel vapor is then drawn into the intake manifold through the canister purge line.
