A. Overview
As the solution for environmental regulations and PM Particle Material) of diesel engine, the low emission
vehicle is getting popular. This vehicle is equipped with an extra filter to collect the soot and burn it again
so that the amount of PM in the exhaust gas passed through the DOC (Diesel Oxidation Catalyst) is
reduced. The CDPF (Catalyst & Diesel Particulate Filter) is an integrated filter including DOC (Diesel
Oxidation Catalyst) and DPF (Diesel Particulate Filter).
For details, refer to Chapter "CDPF".

D. Operation process
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 accumulated 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 sensor. If the temperature is below
600°C, the amount of fuel injected is increased to raise the tem
perature. If the temperature is over
600°C, the amount of fuel injected is 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.

1. OVERVIEW
The propeller shaft transfers the power through the transmission and transfer case to the
front/rear axle differential carrier (final reduction gear). It is manufactured by a thin rounded steel
pipe to have the strong resisting force against the torsion and bending. Both ends of propeller
shaft are connected to the spider and the center of propeller shaft is connected to the spline to
accommodate the changes of the height and length. The rubber bushing that covers the
intermediate bearing keeps the balance of rear propeller shaft and absorbs its vibration.
Function of propeller shaft ▶
Transmits driving torque.
Compensates the angle change (universal joint / CV joint).
Compensates the axial length change (splines for the slip joint). -

1. ESP (Electronic Stability Program)
ESP system contains the ABS (Anti-Lock Brake System), ABD (Automatic Braking Differential),
ASR (Acceleration Slip Regulation), Cornering Control and HBA (Hydraulic Brake Assist System)
functions.
▶Cornering Control (Understeer and Overersteer) Function
This function controls the vehicle stability by applying the braking pressure on each wheel
according to the yaw rate, lateral sensing value and driver’s steering wheel control.
▶HBA (Hydraulic Brake Assist System) Function
HBA (Hydraulic Brake Assist) system helps in an emergency braking situation when the driver
applies the brake fast, but not with sufficient pressure, which leads to dangerously long braking
distance. ECU recognizes the attempt at full braking and transmits the signal calling for full brake
pressure from the hydraulic booster.
