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.

Overview
The cylinder block is made of special cast iron, and contains the major components such as cylinder
head, crankshaft and piston assembly. There are oil and coolant galleries to lubricate and cool the
engine.

1. OVERVIEW
This system purifies the exhaust gas generated by the combustion in the engine to reduce the pollutants
and noise during that arise during combustion.
Harmful materials produced in the combustion process is treated and reduced in the exhaust system.
Harmful materials discharged from the crankcase and fuel tank is drawn into the intake system again to
reduce discharge amount of harmful materials.
Emission aftertreatment system
Catalytic Converter & O2 Sensor
The catalytic converter is a monolith type purification system composed of cordierite which purifies
exhaust gas through the small holes of active monolith catalyst from the exhaust manifold. As exhaus
t
gas passes through the small holes in the layer in the middle, its CO and HC are reduced by
oxidization reaction and its NOx is reduced by reduction reaction to Pt, Ph and Pd. The oxygen
sensor sends signals for feedback and determination of catalyst condition. For detailed description,
see the corresponding section. -
The fuel evaporative gas is a gas evaporated to the atmosphere in the section between the fuel tank and
fuel line, and its main component is hydrocarbon (HC). The fuel evaporative gas is temporarily stored in
the canister, and it is drawn to the engine through the throttle body when the purge control solenoid valve
is open according to the engine operating condition.
Gas in the combustion chamber is sealed by the piston. However, gas is leaked through the gap
between the cylinder and piston and drawn into the crankcase during the compression and explosion
strokes. This gas is blow-by gas and its main components are hydrocarbon and carbon monoxide. If this
gas is drawn into the crankcase, the system can be corroded and oil can be deteriorated. Also, if this
gas is discharged into the air, it can pollute the environment. To prevent these, the blow-by gas
reduction system (also called as crankcase ventilation system) draws the blow-by gas from the
crankcase to the combustion chamber for combustion.

1. OVERVIEW
The ignition system is to supply high voltage generated from the ignition coil to the spark plug. The
G20DF engine is equipped with the independent type direct ignition system that the ignition coil is
installed in each cylinder.
The basic ignition timing in each cylinder is determined by the signals from camshaft position sensor and
crankshaft position sensor.
This ignition system controls the electronic ignition timing received from the engine ECU. To control the
ignition timing precisely, the ECU use the information below:
Engine load
Coolant temperature
Intake air temperature
Engine rpm
Camshaft position sensor (CPS)
Crankshaft position sensor (CKS) -
-
-
-
-
-
If the signal from the camshaft position sensor is not delivered to the engine ECU, the ignition coil and
fuel system cannot be operated.
