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".

2) How it Works at High Speed
In a high speed zone, the amount of exhaust gas increases and it is accompanied with a great force.
Therefore, if the inner diameter of venturi is more widened, the turbine in the turbocharger by the
releasing force of abundant exhaust gas can deliver a more increased energy to the compressor. The
output will increase in submission to the increase of intake air volume.

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.
