Torque change curve of engine and drive shaft
Compression stroke Combustion stroke
Small changes from engine (k):
Damper increases the torque changes to clutchLarge changes from engine (j):
Damper decreases the torque changes to
transaxle by absorbing the impact
3) Operation
Compensating the irregular operation of engine: The secondary flywheel operates almost
evenly so does not cause gear noises
The mass of the primary flywheel is less than conventional flywheel so the engine irregularity
increases more (less pulsation absorbing effect).
Transaxle protection function: Reduces the torsional vibration to powertrain (transaxle) by
reducing the irregularity of engine. -

4) Features
Reduced vibration noise from the powertrain by blocking the torsional vibrations
Enhanced vehicle silence and riding comforts: reduced engine torque fluctuation
Reduced shifting shocks
Smooth acceleration and deceleration -

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) 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.

3) Inspection of Turbine
Thoroughly check the followings.
Must absolutely not operate the turbocharger with the compressor outlet and inlet opened as it
could damage the turbocharger or be hazardous during inspection.
Interference: In case where is trace of interference or smallest damage on the compressor
wheel means, most of times, that abrasion has occurred on the journal bearing. Must inspect
after the overhaul.
Oil Leakage: The reason for oil leakage at the compressor section is the air cleaner, clogged
by substances such as dust, causes the compressor inlet negative pressure. -
-
Rotating in high speed at no-load for extended period of time can cause oil leakage to the
compressor section as oil pressure within the center housing gets higher than pressure
within the compressor housing.
Overuse of engine break (especially in low gear) in down hill makes significantly low
exhaust gas energy compared to the time where great amount of air is required during
idling conditions of the engine. Therefore, amount of air in the compressor inlet increases
but the turbocharge pressure is not high, which makes negative a.
b.
No problem will occur with the turbocharger if above conditions are found in early stage but oil
leaked over long period of time will solidify at each section causing to breakout secondary
defects.
Damages by foreign materials: In case where the compressor wheel is damaged by foreign
materials requires having an overhaul. At this time, it's necessary to check whether the foreign
materials have contaminated intake/exhaust manifold or inside of engine.

1. SPECIFICATION
The engine oil filter element should be changed at the same time with the engine oil.
Regularly check the engine oil level and add the engine oil if necessary.
Remember to check the engine oil level and shorten the cycle to replace the engine oil
under severe driving conditions. -

Severe Driving Condition
Frequent stop-and-go traffic, extended idling, short driving distance below 6 km, driving
distance below 16 km when the outside temperature remains below freezing
Driving in a hilly or mountainous terrain, sandy, or dusty area

1. SYSTEM DESCRIPTION
The starter (start motor) starts the engine with rotational power by converting the electric energy to
the mechanical energy.
When the engine is cranking, the pinion gear meshes with the ring gear. If the ring gear overruns,
the pinion gear clutch overruns to protect the pinion gear.
