LUBRICATION SYSTEM
1. OVERVIEW OIL SEPARATORS
For the D20DT (EURO4) engine, the PCV oil separator's capacity has been increased by 10%
compared to the conventional PCV oil separator for D20DT engine to separate the oil and the
gas more efficiently.

Oil separator
The first separation will happen when blowby gas passes through baffle plates in cylinder head
cover. Then oil and gas will be separated due to cyclone effect after entering the oil separator
inlet port. Separated oil returns to oil pan via oil drain port and the gas will be burnt again after
entering the combustion chamber through air duct hose via PCV valve that opens/closes due to
pressure differences between the intake side and crankcase.
