(8) Swirl control
A. Overview
Variable swirl valve ▶
The strong swirl caused by intake air is important element for anti-locking function in diesel engine. The
swirl control valve partially closes the intake port to generate the swirl according to the engine conditions.
When the engine load is in low or medium range, the swirl could not be generated because the air flow is
slow. To generate strong swirl, there are two passages in intake manifold, and one of them has the valve
to open and close the passage. When the valve closes the passage, the air flow through the another
passage will be faster, and the strong swirl will be generated by the internal structure of the passage. This
swirl makes the better mixture of air and fuel, eventually the combustion efficiency in combustion
chamber could be improved. This provides the enhanced fuel consumption, power and EGR ratio.

OrderMode LCD Display Description
6 Instant fuel
consumptionThe fuel range is calculated based on the distance
driven and fuel consumed every 2 seconds. If the
vehicle speed is below 10 km/h or the engine rpm is
200 rpm or less, the instant fuel economy is not
displayed. The display range is 0.0 to 99.9 km/.
7 Brightness
adjustmentThe brightness of the illumination can be adjusted in 6
steps by pressing the TRIP switch briefly (less than 1
sec.). The display is changed from ILL1 to ILL6 every
time the switch is pressed. If you select one level
within the range and press and hold the TRIP switch,
the brightness level is memorized. If there is no TRIP
switch input for 5 seconds or more, the mode is
switched to TRIP A mode automatically. When the
battery is reinstalled, the brightness level is reset to
level 4.

TRIP/RESET Switch
The mode is changed each time this button is
pressed as follows: TRIP A -> TRIP B -> DTE -
> Driving time -> Average fuel economy ->
Instant fuel consumption -> Tail lamp
illumination level.Windshield de-icer switch
Pressing switch activates windshield
heated glass for approx. 12 minutes
The main switch which allows the
driver to control all door windows,
door lock and window lock from the
driver seat. Tailgate and
outside rearview
mirror heated glass
switch
Pressing switch
activates tailgate and
outside rearview
mirror heated glass
for approx. 12
minutes
Driver power window switchESP ON/OFF switch
Pressing this switch deactivates the ESP (Electronic
Stability Program) system and turns on the ESP OFF
indicator on the instrument cluster. Pressing this
switch again turns off the ESP OFF indicator and
activates the ESP system. Outside rearview mirror folding/unfolding switch
Press the FOLD/UNFOLD switch to fold the outside
rearview mirror and press the switch again to unfold
the mirror.
Rear Fog Lamp Switch
The rear fog lamp comes on when
the rear fog lamp is turned on only
while the front fog lamp is ON.
Steering Wheel Heating
Switch
To heat the steering wheel,
press this switch. To stop
the heating, press it again.
The indicator on the
instrument cluster comes
on when heating and goes
off when turning off. The
heating function stops when
stopping the engine.

2) Cooling System
The transmission cooling system ensures rapid warm-up and constant operating temperature resulting
in reduced fuel consumption and refined shift quality.
It also includes a cooler by-pass within the hydraulic system to allow sufficient cooling and lubrication to
the transmission drivetrain in the event of a blockage in the transmission cooler.
Gear Shift ▶
Coastdown ▶
Torque Demand ▶ Transmission gear change is controlled by the TCU. The TCU receives inputs from various engine and
vehicle sensors to select shift schedules and to control the shift feel and torque converter clutch (TCC)
operation at each gear change
Coastdown downshifts occur at 0% accelerator pedal when the vehicle is coasting down to a stop. To
reduce the shift shock and to improve the shift feeling during downshift, TCU electronically controls the
transmission.
Torque demand downshifts occur (automatically) when the driver demand for torque is greater than the
engine can provide at that gear ratio. If applied, the transmission will disengage the TCC to provide
added acceleration.

3. DUAL MASS FLYWHEEL (DMF)
The dual mass flywheel (DMF) is of having a mass divided into two halves.
While one mass is connected to the engine crankshaft, which is affected by the mass moment of inertia
of the engine, the other mass is affected by one of the transmission.
The divided dual masses are connected to the coil spring and damping system internally.
The DMF has the following benefits: ▶
Reducing fuel consumption by lowering engine speed
Reducing rattling noise and vehicle vibration in all driving ranges
Reducing synchronization wear
Facilitating gear change
Protecting power train parts by preventing excessive load from being delivered -
