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.

Adhesion of soluble organic fraction
(SOF) below 180°C
Purification of soluble organic fraction
(SOF) over 180°C Chemical reaction
formula ·
·
- SOF(HC)+O2 → CO2+H2O
- 2CO+O2 → 2CO2
- 2C2H6+7O2 →
4CO2+6H20
By catalytic action of two primary catalytic
converter, oxidation occurs in order to
decrease HC and CO. ·
Oxygen adheres to catalytic material :
below 180°C ·
Catalytic material supplies each CO and
HC with O2 for their oxidation : above
180°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
filler hole. Run the engine and check for oil leakage
at normal operating temperature.
Stop the engine and wait for 5 minutes.
Check the oil level and add if necessary.
