Method for Reduction of NOx

NOx is generated a great deal in case that combustion tem-
perature and excess air factor are high. EGR valve can de-
crease NOx (30 to 35% decrease) by making temperature of
combustion chamber fall by means of exhaust gas re-
circulation.

• EGR valve is installed on the diesel engine of Musso,

Korando, Istana and Rexton.

And micro switch is installed together to control EGR valve.

• The setting method of micro switch is identical with the

existing one.

RESONANCE FLAP

Function

A pneumatically actuated resonance flap (5) is located on the
intake manifold, and will be opened and closed by load, which
operates resonance flap according to engine and controlled
by ECU and rpm.

Resonance flap closed (at idle/partial load: less
than 3,800 rpm)

The switch valve (7) will be adjusted by ECU and resonance
falp will be colosed. By increasing air flow passage through
dividing intaking air flow toward both air collection housing (8).
This leads to a signficant increase in the torque in the lower
speed range.

Resonance flap open (at full load: over 3,800 rpm)

The switch valve (7) will not be adjusted by ECU and reso-
nance falp (5) will be open. The collected air in the air collec-
tion housing (8) will not be divided and intaking air passage
will be shorten.

Air Cleaner Housing/Element - Check

1. Check the air cleaner body, cover and packing for

deformation, corrosion and damage.

2. Check the air duct for damage.

3. Check the air cleaner element for clogging, contamination

and damage. If the element is partially clogged, remove
the dust or foreign materials with the compressed air. If
the contamination is severe, replace it with new one. Also,
be careful not to contaminate during the replacement.

4. Check the air cleaner housing for clogging, contamination

and damage.

5. If the inside of housing is contaminated, remove the

contaminants.

Air Cleaner Housing - Removal and
Installation

Preceding Work: Removal of air cleaner cover

1. Set aside the return hose and remove the coolant reservoir

bolts.

2. Remove the air cleaner housing bolts.

3. Install in the reverse order of removal.

Notice

When cleaning the air cleaner with compressed air,
direct the air from inside (engine) to outside (ambient
air). Otherwise, contaminants can get into the engine.
