Intake SSANGYONG KORANDO 2013 Workshop Manual

1) Cylinder Head
Overview
The cylinder head assembly is located on the cylinder block.
This contains the combustion chamber, intake and exhaust ports, valve running housing, and oil gallery.
And, this also contains the water jacket to dissipate the heat from the combustion chamber

2) Cylinder Head Cover
The cylinder head cover protects the valve system. It contains the breathing system with PCV valve for
recirculation of blow-by gas. The blow-by gas is induced into the intake manifold through the breather
nipple and PCV Valve. To improve the sealing performance, new bolt pattern is introduced. And, to

3) Camshaft Assembly
Overview
The camshaft is hollow type, and contains the cam, octagon cam, OCV gallery, cam position rotor. The
camshaft operates the intake and exhaust valves.

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. The silent chain provides the
silence during the operation. To improve NVH, the shoulder bolt has been introduced. Overview

5) Chain Rails
The chain rails are used for optimizing the movement of chain drive system. And they also prevent the
chain from contacting each other when the chain is loose, and reduces the chain wear. The chain rail is
normally made of PA (Polyamide nylon), and PA66 and PA46 are used for the chain rails in G20DF
engine. For the tensioner rail, PA46 is used to provide high anti-wear function and high strength since
the load to the rail is huge. Ther is an open area for shoulder bolt hole in the clamping rail. The chain
rails are installed by shoulder bolts.
