Basic principle at low speed
At low speed, it utilizes the principle of venturi. For
example, when air flows through the venturi tube,
the flow speed is faster and the pressure is lower
at the point "A". In this case, if the inner diameter
of venturi is more narrowed, the flow speed is so
much faster (refer to the equation).

4. OPERATING PRINCIPLES
The E-VGT is designed to get more improved engine power in all ranges by controlling the turbine as
follows:
1) How it Works at Low Speed
Normal turbocharger cannot get the turbo effect because the amount of exhaust gas is not enough and
the flow speed is slow in a low speed zone, but VGT allows the flow passage of exhaust to narrow,
resulting in increasing the flow speed of exhaust gas and running the turbine quickly and powerfully.
Therefore, as VGT can intake more air than normal turbocharger, it can give the benefit of the increased
output even in a low speed zone.
Turbocharger lag
The turbocharger is at idle speed when there is no load or it is in the normal driving condition. During
this period, the amount of exhaust gas passing through the turbine is not enough to turn the
compressor wheel (impeller) fast. Therefore, the intake air is not compressed as needed.
Because of this, it takes time for turbocharger to supply the additional power after the accelerator
pedal is depressed. This is called "turbocharger lag".

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
High load driving such as trailer towing
Taxi, patrol service or delivery service (extended idling and excessive driving with low speed) -

3. MAINTENANCE
1) Level Check
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. -
-
-
Operating vehicle with insufficient amount of oil can damage the engine. Make sure the
engine oil level is correct and add oil if necessary.
2) 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.
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. -

1. SYSTEM DESCRIPTION
1) Overview
The lubrication system supplies oil to each lubrication section to prevent friction and wear and to remove
heat from the friction part. As the engine runs, frictional heat is generated on each lubrication section. If
this condition persists, the bearing can be burned and stuck.
In other words, it creates an oil film on each sliding surface to convert solid friction to liquid friction in
order to minimize wear and prevent temperature increasing on the friction part.

3. LUBRICATION
1)Anti-friction
The oil makes a thin film on the surface of sliding components to reduce the wear due to friction.
2)Cooling
The friction makes the heat on the components. The oil absorbs the heat and radiates it or cools it down.
3) Sealing
The piston ring on the piston seals the cylinder. The oil gets into the clearance in piston ring to secure
the sealing for compression pressure and combustion gas.
4) Anti-corrosion
The oil generates the thin film on the surface of components to prevent the material from contacting with
air, water and corrosive gas.
5) Cleaning
The oil transfers the residue of material due to friction, oxidized substance, and carbonized substance
while circulating in the engine by oil pump.

1) Coolant Level Check
Park the vehicle on level ground and apply the parking brake. Stop the engine and wait until it is
cooled down.
The coolant level should be between the MAX and MIN mark on the coolant reservoir.1.
2.
Scalding hot coolant and steam could be blown out under pressure, which could cause serious injury.
Never remove the coolant reservoir cap when the engine and radiator are hot.
Avoid any direct contact of the coolant to the painted body of the vehicle. -

3. CAUTIONS
If 100% of anti-freeze is added, the water pump vane can be damaged and thermal conductivity can
be decreased resulting in poor circulation in the cooling system which leads to overheated engine.
Use of non-recommended coolant could cause damage to the cooling system and overheating of the
engine.
Opening the coolant reservoir cap while the engine is running or hot can cause burns by hot steam o
r
water.
To open the coolant reservoir cap, wrap the cap with a wet towel or thick cloth after the engine is
cooled down sufficiently.
If cool water is added to the heated engine, the engine or radiator can be deformed.
The anti-freeze in the coolant can damage the painted surface, so avoid the contact of the coolant to
the painted body.
The anti-freeze and water should be mixed in proper mixture ratio. Never add only water when
adding coolant.
If the anti-freeze content is too low, the coolant can be frozen while the engine can be overheated if
anti-freeze content is too high. -
