2) Sytem Composition for Soot Combustion
When the engine is running in low load range, the temperature of exhaust gas is decreased as
the amount of fuel supplied is decreased. To burnt the soot filtered in the CDPF, the control
system should be installed to check the operating range and increase the temperature o
f
exhaust gas by controlling the amount of fuel supplied and and intake air.
Two temperature sensors and one differential pressure sensor monitor the CDPF's operating
range. According to theses sensors' information, the throttle flap decreases the intake ai
r
entered to the throttle body. Also, the fuel injection pattern is added to increase the temperature
of exhaust gas for soot combustion.
There are two fuel injection patterns (pilot injection and main injection). As the CDPF is
installed, the post injection pattern is added.
3) Post Injection and Air Mass Control
When the differential pressure sensor detects the pressure difference between the front and the
rear side of CDPF, the sensor sends signal indicating the soot is acumulated and the post
injection is performed to raise the temperature of exhaust gas. The amount of fuel injected is
determined according to the temperature of exhaust gas detected by the rear temperature

decreased or not controlled.
When the engine is running in low load range, the amount of post injection and the amount of
intake air are controlled.
It is to raise the temperature by increasing the amount of fuel while decreasing the amount of
intake air.

BRAKS SYSTEM

4) Master Cylinder
The brake master cylinder is designed to
convert the force from the brake maste
r
cylinder to the high hydraulic pressure. The
brake system uses the tandem type master
cylinder with in-line 2 pistons.
The in-line 2 pistons generate the hydraulic
pressure. The piston cup on the piston keeps
the sealing conditions in cylinder and
prevents the oil leaks. The hydraulic
pressure generated by the primary piston is
delivered to the front wheels, and the
hydraulic pressure generated by the
secondary piston is delivered to the rea
r
wheels.
5) Brake Booster
The brake booster is a power assist device for brake system. It relieves the pedal depressing
force by using the pressure difference between the vacuum pressure generated by vacuum
pump in intake manifold and the atmospheric pressure.
▶Pressure distribution at working
When depressing the brake pedal, the push
rod (1) in booster pushes the poppet (2) and
valve plunger (3). The poppet (2) pushes the
power piston seat (5) resulting in closing the
vacuum valve (9). The chamber (A) and (B)
in power cylinder are isolated and the valve
plunger (3) is separated from the poppet (2).
And then the air valve (6) opens and ai
r
flows into the chamber (B) through filter.
Then, the power piston (5) pushes the
master cylinder push rod (7) to assist the
brake operation.
▶Pressure distribution after working
When releasing the brake pedal, the valve
plunger (3) returns back to the original
position by return spring (4) and the air valve
(6) closes. At this time, the vacuum valve (9)
opens and the pressure difference between
chamber (A) and (B) in power cylinder is
eliminated. Accordingly, the power piston (5)
returns back to original position by the
reaction of master cylinder (10) and the
diaphragm return spring (8).
