Evaporative Emissions System: Description and Operation
System Description
Fig. 3 EEC system
The evaporative emission control system, Fig. 3, draws fuel vapor, emitted from the fuel tank and carburetor when the engine is not operating, into a
charcoal canister. The system comprises a tank pressure control valve, a charcoal canister, a venting switching valve, a thermal vacuum valve and
connecting lines. When the engine is not operating, fuel vapor is stored in the charcoal canister. When the engine is started, the stored vapor is mixed
with ambient air and fed directly to the intake manifold for combustion.
