(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.

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 -
