(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.

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.

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 -
