4. INTAKE/EXHAUST MANIFOLD
1) Intake Manifold
Intake manifold is installed on the cylinder head with 8 bolts. The variable swirl valve is introduced to
improve the EGR gas mixture and turbulence in combustion chamber and to decrease the exhaust
gas.
2) Exhaust Manifold
Exhaust manifold is installed on the cylinder head with 10 stud bolts and nuts. EGR port is integrated
in cylinder head.Components ▶

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.

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.

Components ▶
Cylinder head
Cylinder head contains cam position sensor, vacuum pump, intake manifold, exhaust manifold and
valve assembly. Vacuum pump and the high pressure (HP) pump are driven by Camshaft and valves
are install in vertical direction. This enables the compact layout in cylinder head assembly.

Location of Expansion Plugs
1) Cylinder Head
(1) Overview
The cylinder is made by gravity casting and the water jacket is integrated type.
The cylinder oil passage is drilled and sealed by cap.
The Camshaft bearing cap is also made by casting and installed on the 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.

3) Valve Assembly (Installed in Cylinder Head)
(1) Features
Automatic valve clearance adjuster by hydraulic pressure (Maintenance Free) - Hydraulic lash
Optimized adjustment of valve clearance reduces the valve noise.
Roller type finger follower reduces the friction loss.
Vertical installation.
