(3) Cautions before service
Prolonged exposure to the engine oil make cause a skin cancer or an irritation.
Used engine cotains the hazardous material that may cause the skin cancer. Do not allow the used
engine to make contact with your skin.
Make sure to wear the protection gloves and goggle when handling the engine oil. If contact happens,
rinse affected areas immediately with plenty of water. Do not wash it with gasoline or solvent. If
irritation persists, consult a doctor.
Improperly disposed engine oil can pollute the environment. Dispose used engine oil in accordance
with local environmental regulations. -

(5) Tightening the fastener
If fine dust or foreign material enters into DI engine's fuel system, there can be serious damages
between HP pump and injectors. So, be sure to cover removed fuel system components with cap
and protect removed parts not to be contaminated with dirt. (Refer to cleanness in this manual
while working on DI engine fuel system)
When working on the fuel line between priming pump and injector (including return line), always
plug the openings with caps to prevent foreign materials or dust from entering to the openings and
connections.
The HP fuel supply pipe (HP pump to fuel rail) and HP fuel pipe (Fuel rail to injector)
should be replaced with new ones when removed. 1.
2.
3. Scalding hot coolant and steam could be blown out under pressure, which could cause serious injury.
Never remove the coolant reservoir cap when the engine and radiator are hot.
(4) Lubrication system
3) Fuel and Oil System
If work on the fluid system such as fuel and oil, working area should be well ventilated and smoking
should be prohibited.
Gasket or seal on the fuel/lubrication system should be replaced with new ones and bolts and nuts
should be tightened as specified. -
-Clean the mating surfaces before tightening.
Place the marks with paint to tighten by angle if the angle wrench is not available. -

(2) Cylinder pressure leakage test
If the measured value of the compression pressure test is not within the specifications, perform the
cylinder pressure leakage test.Specified value ▶
Perform this test in the sequence of firing order.
Do not test the cylinder pressure leakage with wet type test procedure. (do not inject the engine oil
into the combustion chamber) -
-
Test condition: normal engine operating
temperature (80˚C)Specified value
Whole engine below 25%
at valve and cylinder head gasket below 10%
at piston ring below 20%
Crank the engine for approx. 10 seconds by
using the start motor. 2.
Record the test result and measure the
compression pressure of other cylinders with
same manner. 3.
If the measured value is out of specified
value, perform the cylinder pressure leakage
test. 4.

Pump capacity: 210 cc/rev
Camshaft speed: 375 to 3,000 rpm
Lubrication temperature: -40 to
155°C
Oil: 5W30
Drive type: Driven by exhaust
Camshaft sprocket
2. VACUUM PUMP
Vacuum pump generates the vacuum pressure and supplies it to EGR cooler bypass solenoid. This
pump is single vane type and displacement is 210 cc/rev. The lubrication oil is supplied through the hole
in hollow shaft.
Components ▶
EGR cooler bypass valve
This valve is controlled by ECU.
When the engine is cooled, the
exhaust gas goes to combustion
chamber without passing through
EGR cooler because the valve is
closed by vacuum pressure.

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.

2. MAINTENANCE AND INSPECTION
1) Maintenance Procedures for DI Engine Fuel System
Always keep the workshop and lift clean (especially, from dust).
Always keep the tools clean (from oil or foreign materials).
Wear a clean vinyl apron to prevent the fuzz, dust and foreign materials from getting into fuel system.
Wash your hands and do not wear working gloves. 1.
2.
3.
Follow the below procedures before starting service works for fuel system.
If the problem is from HP pump, fuel supply line or injector, prepare the clean special tools and sealing
caps to perform the diagnosis for DI engine fuel system in this manual. At this point, thoroughly clean
the related area in engine compartment. 4.
Clean the engine compartment before starting service works.
