Fuel Evaporative Emission
Control System
The fuel evaporative emission control
system is designed to prevent air pol-
lution caused by evaporative tosses
from the fuel system.
This is accomplished by a proper sys-
tem which prevents the release into the
atmosphere of fuel vapors from the
fuel tank.
The fuel vapors from the fuel lank ftow
into the activated charcoal carbon can-
ister where they are absorbed and
stored when the engine is not opera-
ting.
When the engine is running, the fuel
vapors retained in carbon canister are
purged through a line which conveys
them to intake manifold.
The system consists essentially of:
— Sealed filler cap.
— Limited-filling tank,
— Vapor-liquid separator.
— Two-way valve.
— Vapor vent line.
— Carbon canister.
— Purge line.
