Intake/Exhaust Camshafts
2) Camshaft
(1) Overview
Hollow type camshaft contains cam, octagon cam, HP pump gear and intake/exhaust gears.
Camshaft operates the intake/exhaust valves, vacuum pump and HP pump, and transfers the engine
oil to vacuum pump through the internal oil passage.

2) Fuel System Flow Diagram
The fuel from the fuel tank is supplied to the fuel heater of fuel filter/priming pump and then low
pressure generated by the low pressure pump (built into HP pump) is transmitted to the HP pump.
The fuel pressure at the HP pump is controlled by the IMV valve, and the maximum allowed pressure
is 1,800 bar. The compressed fuel at the fuel pump is delivered to the rail, and injected by the injectors
according to the injection signals. The injection method is the same with the conventional method; Fuel
return by backleak which operates the needle valve.
The major difference is that the fuel return line is connected to the fuel filter inlet port, not the HP pump
venturi.
The pressure from the high pressure pump is increased to 1,800 bar from 1,600 bar, and the pump is
now installed to the cylinder head (cylinder block for previous model). The fuel pressure is generated
by the operation of intake camshaft and gears. The specifications for the IMV valve and the fuel
temperature sensor are not changed.

1. OVERVIEW
▶DC 5-Speed Automatic Transmission
DCAG 5-speed automatic transmission is an electronically controlled 5-speed transmission with a
lockup clutch in the torque converter. The ratios for the gears are realized by three planetary gear sets.
The 5th gear is designed with a step-up ratio of 0.83 as an overdrive. The selector lever is controlled by
electronically and mechanically. The gears are shifted by the corresponding combination of three
hydraulically actuated multiple-disc brakes, three hydraulically actuated multiple-disc clutches and two
mechanical one-way clutches. This electronically controlled automatic transmission adjusts the
operating pressure to provide proper shifting in relation to engine power. This function improves shifting
quality significantly. And, the driver can select "S" (Standard) mode or "W" (Winter) mode according to
the driving conditions. This automatic transmission provides two gears even during reverse driving. The
internal sensors and controls are connected to TCU by cylindrical 13-pin connector.
DCAG 5-speed automatic transmission offers the following advantages:
Improved shifting quality
More gears
Extended working life and reliability
Reduced fuel consumption 1.

1. OVERVIEW
1) Characteristics of Transmission
Forward and Reverse gears are helical gear.
The clutch is operated by concentric slave cylinder (CSC).
To prevent the improper gear shift, semi-remote control system has been introduced.
To prevent the gears from engaging improperly, the synchronizer mechanisms and independent
interlock systems are installed on 1/2 gears, 3/4 gears, 5/6 gears and reverse gear.
The High-Force system for reverse gear shift has been introduced.
The synchronizer has three types: Triple (1, 2, 3, R), Double (5), Single (4, 6) -

1. OVERVIEW
By using the planetary gear sets, two-gears shift type part time transfer case achieves direct
connection when selecting 4WD "HIGH" and 2.48 of reduction gear ratio when selecting 4WD
"LOW". The silent chain in transfer case transfers the output power to front wheels.
The simple operation of switches on instrument panel allows to shift between "2H" and "4H" easily
while driving (for 4L: stop vehicle first). The warning lamp warns the driver when the system is
defective.
