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 f\
or better NVH.
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 ty pe. Upper chain drives HP pump connected to intake
Camshaft by driving exhaust camshaft sprocket, and lowe r chain drives oil pump to lubricate the engine.

3. CAUTIONS FOR DI ENGINE
1) Cautions for DI Engine
This chapter describes the cautions for DI engine equipped vehicle. This includes the water separation
from engine, warning lights, symptoms when engine malfunctioning, causes and actions.
DI Engine 1.
Comparatively conventional diesel engines, DI engine controls the fuel injection and timing electrically,
delivers high power and reduces less emission..
System Safety Mode 2.
When a severe failure has been occurred in a vehicle, the system safety mode is activated to protect the
system. It reduces the driving force, restricts the engine speed (rpm) and stops engine operation. Refer
to "Diagnosis" section in this manual.
Engine CHECK Warning Lamp 3.
The Engine CHECK warning lamp on the instrument cluster comes on when the fuel or
major electronic systems of the engine are not working properly. As a result, the
<008c0095008e00900095008c02c5009a004700970096009e008c009900470096009c009b0097009c009b00470094008800a00047008b008c008a0099008c0088009a008c0047009600990047009b008f008c0047008c0095008e00900095008c0047009400
8800a00047009a009b0088009300930055>
Water Separator Warning Lamp 4.
When the water level inside water separator in fuel filter exceeds a certain level (approx.
45 cc), this warning light comes on and buzzer sounds.
Also, the driving force of the vehicle decreases (torque reduction). If these conditions
occur, immediately drain the water from fuel filter.

2) ECU Control
(1) Function
a. ECU Function
ECU receives and analyzes signals from various sensors and then modifies those signals into
permissible voltage levels and analyzes to control respective actuators.
ECU microprocessor calculates injection period and injection timing proper for engine piston speed and
crankshaft angle based on input data and stored specific map to control the engine power and emission
gas.
Output signal of the ECU microprocessor drives pressure control valve to control the rail pressure and
activates injector solenoid valve to control the fuel injection period and injection timing; so controls
various actuators in response to engine changes. Auxiliary function of ECU has adopted to reduce
emission gas, improve fuel economy and enhance safety, comforts and conveniences. For example,
there are EGR, booster pressure control, autocruise (export only) and immobilizer and adopted CAN
communication to exchange data among electrical systems (automatic T/M and brake system) in the
vehicle fluently. And Scanner can be used to diagnose vehicle status and defectives.

47009b009600470052005f005c00b6006a004700880095008b> protected from factors like oil,
water and electromagnetism and there should be no mechanical shocks.
To control the fuel volume precisely under repeated injections, high current should be applied instantly
so there is injector drive circuit in the ECU to generate necessary current during injector drive stages.
Current control circuit divides current applying time (injection time) into full-in-current-phase and hold-
current-phase and then the injectors should work very correctly under every working condition.
b. Control Function
Controls by operating stages
To make optimum combustion under every operating stage, ECU should calculate proper injection
volume in each stage by considering various factors.
Starting injection volume control
During initial starting, injecting fuel volume will be calculated by function of temperature and engine
cranking speed. Starting injection continues from when the ignition switch is turned to ignition
position to till the engine reaches to allowable minimum speed.
Driving mode control
If the vehicle runs normally, fuel injection volume will be calculated by accelerator pedal travel and
engine rpm and the drive map will be used to match the drivers inputs with optimum engine power. -
