This system controls flow rate of EGR led from exhaust manifold
to intake manifold. The opening of the EGR by-pass passage in the
EGR volume control valve changes to control the flow rate. A
built-in step motor moves the valve in steps corresponding to the
ECM output pulses. The opening of the valve varies for optimum
engine control. The optimum value stored in the ECM is determined
by considering various engine conditions.
The EGR volume control valve remains close under the following
conditions.
+
Engine stopped
+
Engine starting
+
Low engine coolant temperature
+
Excessively high engine coolant temperature
+
High engine speed

COMPONENT DESCRIPTION
NLEC0764S02
EGR Volume Control Valve
NLEC0764S0201
The EGR volume control valve uses a step motor to control the flow
rate of EGR from exhaust manifold. This motor has four winding
phases. It operates according to the output pulse signal of the
ECM. Two windings are turned ON and OFF in sequence. Each
time an ON pulse is issued, the valve opens or closes, changing
the flow rate. When no change in the flow rate is needed, the ECM
does not issue the pulse signal. A certain voltage signal is issued
so that the valve remains at that particular opening.

This system has a swirl control valve in the intake manifold.
Under normal driving conditions, the swirl control valve closes,
generating a strong swirl in the combustion chamber. This pro-
motes the mixing of fuel and air for stable combustion.
Under high-load conditions, the swirl control valve opens. By
obtaining a volume of air for an increase in fuel, combustion that
does not easily emit black smoke is achieved.
The solenoid valve controls swirl control valve’s shut/open condi-
tion. This solenoid valve is operated by the ECM.

NLEC1266S02
Swirl Control Valve Control Solenoid Valve
NLEC1266S0201
The swirl control valve control solenoid valve responds to signals
from the ECM. When the ECM sends an ON (ground) signal, the
solenoid valve is bypassed to apply vacuum pump vacuum to the
swirl control valve actuator. This operation closes the swirl control
valve. When the ECM sends an OFF signal, the vacuum signal is
cut and the swirl control valve opens.
