5) Advantages
Improved torque response by using 3-stage type spring: Strengthens the torque response in all
ranges (low, medium, and high speed) by applying respective spring constant at each range.
Stable revolution of the primary and secondary wheel by using planetary gear: Works as auxiliary
damper against spring changes
Less heat generation due to no direct friction against spring surface: Plastic material is covered on
the spring outer surface
Increased durability by using plastic bushing (extends the lifetime of grease) -

6) Drive Plate
Drive plate receives the power from the start motor when starting the engine. With this, the drive plate
initially drives the power train system. And, it is connected to the torque converter to transfer the engine
torque to the power train system.

2) ECU Control
(1) Function
a. ECU Function
ECU receives and analyzes signals from various sensors and then modifies those signals into
permissible voltage levels and analyzes to control respective actuators.
ECU microprocessor calculates injection period and injection timing proper for engine piston speed
and crankshaft angle based on input data and stored specific map to control the engine power and
emission gas.
Output signal of the ECU microprocessor drives pressure control valve to control the rail pressure and
activates injector solenoid valve to control the fuel injection period and injection timing; so controls
various actuators in response to engine changes. Auxiliary function of ECU has adopted to reduce
emission gas, improve fuel economy and enhance safety, comforts and conveniences. For example,
there are EGR, booster pressure control, autocruise (export only) and immobilizer and adopted CAN
communication to exchange data among electrical systems (automatic T/M and brake system) in the
vehicle fluently. And Scanner can be used to diagnose vehicle status and defectives.
Operating temperature range of ECU is normally -40 to +85°C and protected from factors like
oil, water and electromagnetism and there should be no mechanical shocks.
To control the fuel volume precisely under repeated injections, high current should be applied instantly
so there is injector drive circuit in the ECU to generate necessary current during injector drive stages.
Current control circuit divides current applying time (injection time) into full-in-current-phase and hold-
current-phase and then the injectors should work very correctly under every working condition.
b. Control Function
Controls by operating stages
To make optimum combustion under every operating stage, ECU should calculate proper injection
volume in each stage by considering various factors.
Starting injection volume control
During initial starting, injecting fuel volume will be calculated by function of temperature and engine
cranking speed. Starting injection continues from when the ignition switch is turned to ignition
position to till the engine reaches to allowable minimum speed.
Driving mode control
If the vehicle runs normally, fuel injection volume will be calculated by accelerator pedal travel and
engine rpm and the drive map will be used to match the drivers inputs with optimum engine power. -

A fourth correction is made according to the pressure error.
This correction is used to reduce the injection timing advance when the pressure in the rail is higher
than the pressure demand.
A fifth correction is made according to the rate of EGR.
This correction is used to correct the injection timing advance as a function of the rate of exhaust
gas recirculation. -
-
When the EGR rate increases, the injection timing advance must in fact be increased in order to
compensate for the fall in termperature in the cylinder.
A. Main Flow Control
The main flow represents the amount of fuel injected into the cylinder during the main injection. The
pilot flow represents the amount of fuel injected during the pilot injection.
The total fuel injected during 1 cycle (main flow + pilot flow) is determined in the following manner.
When the driver depress the pedal, it is his demand which is taken into account by the system in
order to determine the fuel injected.
When the driver release the pedal, the idle speed controller takes over to determine the minimum
fuel which must be injected into the cylinder to prevent the enigne from stalling. -
-
The driver demand is the translation of the pedal position into the fuel demand. It is calculated as a
function of the pedal position and of the engine speed. The driver demand is filtered in order to limit the
hesitations caused by rapid changes of the pedal position. A mapping determines the maximum fuel
which can be injected as a function of the driver demand and the rail pressure. Since the flow is
proportional to the injection time and to the square root of the injection pressure, it is necessary to limit
the flow according to the pressure in order to avoid extending the injection for too long into the engine
cycle. The system compares the driver demand with this limit and chooses the smaller of the 2 values.
The driver demand is then corrected according to the coolant temperature. This correction is added to
the driver demand.

▶Auto Door Lock
The door lock system outputs "LOCK" when the vehicle speed maintains over 50 km/h. However, it
doesn't output "LOCK" when all doors are locked or failed.
If any of doors is unlocked after outputting "LOCK" in step 1, outputs "LOCK" up to 5 times (except
step (1)) at the interval of one second.
If any of doors is unlocked after 5 times of "LOCK" outputs, the door(driver's/passenger's/
rear) is regarded as "FAIL".
If the door that was regarded as fail is changed(UNLOCK to LOCK), it will be recognized as a
normal one.
If any door is regarded as FAIL, the auto door lock function does not work. (if it is occurred when the
vehicle speed is over 50 km/h, the auto door lock output does not occur even if the vehicle speed
falls below 50 km/h and accelerates again to over 50 km/h.) Nonetheless, the central door lock
function works properly.
When the system receives "UNLOCK" signal from a door switch, it outputs "LOCK" signals 5 times.
If additional "LOCK" signal from another door switch is detected during the period, the system
outputs five "LOCK" signals 5 times for the switch.
The door lock system outputs "UNLOCK" automatically if the "LOCK" output conditions are
established by this function or the key is cycled(IGN=OFF) (even when there is no "LOCK" output
while the vehicle speed maintains over 50 km/h under lock condition). (If the LOCK condition is
established with the ignition switch ON, the system outputs UNLOCK signal unconditionally when
turning the ignition switch to OFF position.) However, when the ignition key is turned to "OFF"
position, the lock output conditions will be cancelled.
The "FAIL" condition of the door will be erased when the ignition key is turned to "OFF" position. 1.

1. OVERVIEW
The hydraulic clutch transmits the force required to operate the clutch pedal to the concentric slave
cylinder fitted to the clutch housing as a hydraulic pressure.
(The hydraulic pressure is transmitted in the following order: Clutch pedal - Clutch master cylinder -
Clutch pipe - Clutch damper - Clutch pipe and hose - Concentric slave cylinder - Pressure plate -
Flywheel.)
If a driver depress the clutch pedal, the hydraulic pressure is generated in the master cylinder. It is
transmitted to the concentric slave cylinder through the pipe, resulting in the cylinder being forced out.
At this time, the clutch disc is forced against the cylinder by pushing the cover. This, in turn, remove the
flywheel from the pressure plate. As a consequence, the power from the engine will be cut off and the
gear change can be carried out.
