3) Features of DMF
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 -

-
4) Advantages of DMF
Improved torque response by using 2-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) -

Functions
Piston transfers the combustion energy from engine to connecting rod.
C. Snap ring
Locks the piston pin. - A. Piston ring
#1 ring (Top ring) : Prevents the high pressurized combustion gas from leaking into crank chamber,
and prevents the engine oil getting into combustion chamber.
#2 ring: Scrapes the engine oil on the cylinder bore, and prevents the leaked combustion gas from #1
ring from leaking into the crank chamber.
Oil ring: Scrapes the engine oil on the cylinder bore. -

-
B. Piston pin
Connects the piston the connecting rod, and transfers the linear movement of piston to connecting rod
to convert it to rotating energy. -

Overview
Crankshaft is installed on the cylinder block. The crankshaft converts the reciprocative movement of
piston to the rotatinal movement.

2. MAINTENANCE
Park the vehicle on a level ground and apply the parking brake. Stop the engine and wait more than 5
minutes.
Pull out the dipstick and wipe it with a clean cloth. Reinsert it all the way.
Pull out it again and check the oil level.
The oil level should be between the maximum (Max) mark and minimum (Min) mark on the oil
dipstick. Oil should be replenished before the level goes below the minimum mark. -

Engine oil dipstickEngine oil cap
Max Min
Replenishment
If the level gets to the lower point, open the filler cap on top of the cylinder block and add the genuine oil
without exceeding the level of the upper mark.
Recheck the oil level after 5 minutes.Operating vehicle with insufficient amount of oil can damage the engine. Make sure the engine oil level
is correct and add oil if necessary.
Regularly check the engine oil level and add Ssangyong genuine engine oil if necessary.
Clean the dipstick with clean cloth so that any foreign materials cannot get into the engine.
The oil should not go above the upper mark on the dipstick.
The engine oil may be consumed more if the engine is new. -
