EVAP Canister Purge Control Solenoid Valve
COMPONENT DESCRIPTION
EVAP canister purge control solenoid valve
The EVAP canister purge control solenoid valve responds to
signals from the ECM. When the ECM sends an OFF signal, the
vacuum signal (from the throttle body to the EVAP canister purge
control valve) passes through the EVAP canister purge control
solenoid valve. The signal then reaches the EVAP canister purge
control valve.
When the ECM sends an ON (ground) signal, the vacuum sig-
nal is cut.

EVAP Canister Purge Control Solenoid Valve
(Cont'd)
EC-142

COMPONENT DESCRIPTION
The fuel injector is a small, precise solenoid valve. When the
ECM supplies a ground to the injector circuit, the coil in the
injector is energized. The energized coil pulls the needle valve
back and allows fuel to flow through the injector into the intake
manifold. The amount of fuel injected depends upon the injection
pulse duration. Pulse duration is the length of time the injector
remains open. The ECM controls the injection pulse duration
based on engine fuel needs.

This system has a swirl control valve in the intake
passage of each cylinder.
While idling and during low engine speed
operation, the swirl control valve closes. Thus the
velocity of the air in the intake passage increases,
promoting the vaporization of the fuel and produc-
ing a swirl in the combustion chamber.
Because of this operation, this system tends to
increase the burning speed of the gas mixture,
improve fuel consumption, and increase the stabil-
ity in running conditions.
Also, except when idling and during low engine
speed operation, this system opens the swirl con-
trol valve. In this condition, this system tends to
increase power by improving intake efficiency via
reduction of intake flow resistance, intake flow.The solenoid valve controls swirl control valve's
shut/open condition. This solenoid valve is oper-
ated by the ECM.
