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.
