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.
Location
Exhaust camshaft
Intake camshaft
Timing marks
Align the timing marks (A) on the camshaft
flange and camshaft cap when installing the
intake/exhaust camshaft.

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

Layout and Location
Hydraulic chain tensioner
In G20DF engine, the hydraulic auto tensioner is used to keep the tension for chain drive system of
engine. The auto tensioner is operated by the spring in tensioner and the hydraulic pressure.

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.

1) Overview
Dual mass flywheel (DMF)
- Manual transaxleDrive plate
- Automatic transaxle
Dual mass flywheel reduces the unbalanced
rotation of crankshaft in manual transaxle
equipped vehicle. The flywheel is installed on the
crankshaft and is engaged to the clutch disc to
transfer the driving torque from the engine to the
powertrain system. Additionally, DMF decreases
the rattling noise in transaxle and the vehicle
vibration by reducing the differences of torque and
rotational speed due to the combustion in engine.The drive plate initially drives the powertrain
system by using the power from the start motor
when starting the engine. The drive plate is
installed on the crankshaft and is engaged to the
torque converter of automatic transaxle to transfer
the driving torque from the engine to the powertrain
system.
