ENGINE EXHAUST SYSTEM
1. EXHAUST SYSTEM
When you are inspecting or replacing exhaust system components, make sure there is
adequate clearance from all points on the underbody to avoid possible overheating of the
floor panel and possible damage to the passenger compartment insulation and trim
materials. -
Check the complete exhaust system and the nearby body areas and trunk lid for broken,
damaged, missing or mispositioned parts, open seams, holes, loose connections, or othe
r
deterioration which could permit exhaust fumes to seep into the trunk may be an indication of a
problem in one of these areas. Any defects should be corrected immediately.
2. MUFFLER
Aside from the exhaust manifold connection, the exhaust system uses a flange and seal joint
design rather than a slip joint coupling design with clamp and U-bolts. If hole, open seams, o
r
any deterioration is discovered upon inspection of the front muffler and pipe assembly, the
complete assembly should be replace, the complete assembly should be replaced. The same
procedure is applicable to the rear muffler assembly.
Heat shields for the front and rear muffler assembly and catalytic converter protect the vehicle
and the environment from the high temperatures that the exhaust system develops.
3. CATALYTIC CONVERTER
When jacking or lifting the vehicle from the body side rails, be certain that the lift pads do
not contact the catalytic converter, as this could damage the catalytic converter. -
Use of anything other than unleaded fuel will damage the catalyst in the catalytic converter. -
The catalytic converter are emission-control devices added to the exhaust system to reduce
pollutants from the exhaust pipes.
The oxidation catalyst is coated with a catalytic material containing platinum and palladium,
which reduces levels of hydrocarbon (HC) and carbon monoxide (CO) from the exhaust gas.
The three-way catalyst has coatings which contain platinum and rhodium, which additionally
lower the levels of oxides of nitrogen (NOx).

4. CATALYTIC CONVERTE STRUCTURE
The Catalytic converter of monolith type
consists of 2 walled metal bodies which is
made of Cordierite.
The principal element of converter consists
of the materials like Alumina or oxidized
Serume in order to apply to Ceramic
Monolith.
Washer coat operates first, and catalytic
metal elements (Pt, Pd, Rh) operates to
washer coat next.
Monolith type is lighter than other types,
easy to manufacture and quickly approaches
to proper temperature.
Washer coat is used to make a contact
surface with exhaust gas bigger by adhering
closely to small holes of inner layer.
If a lead compound or phosphorus adheres
to the surface and the temperature rises, its
surface is decreased.
The total area of general monolith converte
r
is about 45,000 ~ 500,000 ft3. (10 times of a
football field)
Generally Alumina (AL2 O3) is used as a
raw material and its 7 phases of gamma,
delta, theta have big areas and high stability
for the temperature, and nowadays gamma
Alumina is used usually.

5. CATALYTIC CONVERTER AND TEMPERATURE
Catalytic converter has the normal function
of purification at a range of the temperature.
Because it has a weak point of decreasing
of the purification rate in the condition o
f
continuous high temperature, it should keep
the temperature range of 400 to 500°C for
normal condition.
HC purification rate becomes bette
r
according to the increase of temperature in
the normal range of temperature.
CO purification rate becomes the best nea
r
the temperature of 450°C, and NOx does
so near the temperature of 400 to 500°C.

1) Method for Reduction of
NOx
NOx is generated a great deal in case that
combustion temperature and excess ai
r
factor are high. EGR valve can decrease
NOx (30 to 35% decrease) by making
temperature of combustion chamber fall by
means of exhaust gas recirculation.
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. ·

3) Replacement
Install the socket wrench A9910 0050A
(103 589 02 09 00) on the oil filter cover (2).
1.
Tighten the bolts on the socket wrench to
remove the screw cover.
Set a wrench on the bolt on the top of
socket wrench and turn it to remove the
oil filter cover.
Remove the oil filter element.
2.
3.
Wrap the used filter element with a shop
cloth so that the oil cannot drop on the floor.
Remove the drain plug (1) and drain the
engine oil completely.
4.
To drain the oil easily, remove the oil filler
cap (3).
Clean the drain plug and reinstall it.
5.
Replace the seal washer with new one.
Replace the O-ring (5) on the oil filter
cover with new one.
6.
When replacing, apply the engine oil on the
O-ring.
Insert new oil filter element into the oil
filter housing.
Temporarily tighten the oil filter cover (2)
by hands and then tighten it with the
socket wrench A9910 0050A
(103 589 02 09 00).
7.
8.
Pour the engine oil through the engine oil
