5. CYLINDER HEAD COVER AND OIL SEPARATOR
The cylinder head cover is made by high strength plastic to reduce the weight. The multi twist type oil
separator improves the oil consumption.
Components

2) Oil Separator
Oil separator separates the particle in blow-by gas to minimize the engine oil consumption and reduces
the inflow oil from intake system into the combustion chamber. The separated oil returns to oil pan
through cylinder head.

Intake/Exhaust Camshafts
2) Camshaft
(1) Overview
Hollow type camshaft contains cam, octagon cam, HP pump gear and intake/exhaust gears.
Camshaft operates the intake/exhaust valves, vacuum pump and HP pump, and transfers the engine
oil to vacuum pump through the internal oil passage.

1) Chain Drive
(1) Overview
The drive chain is single chain drive system with simple design and variable performance, and it utilizes
the hydraulic tensioner to reduce the wave impact generated by the chain. This chain is light weight and
has high durability through single bush chain. Shoulder bolts are used for better NHV.
7. CHAIN AND GEAR DRIVE SYSTEM
D20DTR engine uses single stage chain drive system. Timing chain drives the exhaust side and gear
drive the intake side. Timing chain is single bush type. Upper chain drives HP pump connected to intake
Camshaft by driving exhaust cam shift sprocke, and lower chain drives oil pump to lubricate the engine.
