Electrical equipment ▶
Electric devices should be handled more carefully.
Currently, the engine has a lot of electric devices. there could be poor engine performance, incomplete
combustion and other abnormal symptoms due to short circuit or poor contact.
Before work on engine and each electrical equipment, be sure to disconnect battery negative (-)
terminal.
When replacing the electric device, use only genuine part and check the conditions of connections
and grounds. Loosened connection or ground make cause a fire and personal injury. -
-Fuel and lubrication system ▶
Do not allow the fluid and engine oil to make contact with the body paintwork and hoses.
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.
After removal/installation works, be sure to check whether there is leak on the connecting section. -

If fine dust or foreign material enters into DI engine's fuel system, there can be serious damages in HP
pump and injectors. Thus, be sure to plug the inlets of removed fuel line 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)

EGR cooler bypass valve
Exhaust gas goes to combustion
chamber without through EGR
cooler in engine cooled, and the
valve is closed by vacuum
pressure.
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.

3. ENGINE MOUNTINGS
D20DTF engine mounting is 4-point mounting type and supports the engine and transaxle.
Front and rear mountings are rubber type and support the torque reaction. Left and right mountings
support the power train rods and torque reaction. Additionally, left mounting is hydraulic type and supports
the engine vibration.

7. CHAIN AND GEAR DRIVE SYSTEM
D20DTF engine uses single stage chain drive system. Timing chain drives the exhaust side and gear drive
the intake side. Timing chain is single bush type. Upper chain drives HP pump connected to intake
Camshaft by driving exhaust cam shift sprocke, and lower chain drives oil pump to lubricate the engine.
And, MBU (Mass Balance shaft Unit) drive gear drives MBU.
Components ▶
Chain lower bush
Chain type: single bush
Chains: 60 EAOil pump sprocket
Teeth: 20 EA
Mechanical type tensioner
Operated by internal spring
The timing links (gold color) on the timing chain are aligned with the timing marks on the
crankshaft sprocket and the camshaft sprocket whenever the crankshaft rotates 8 turns.

Oil pan assembly
8. OIL PAN
The oil pan in D20DTF engine improves the noise and vibration. Especially, the oil drainage is very easier
than before. The oil level sensor in oil pan monitors the oil level and turns on the oil level warning lamp on
the meter cluster when the oil level goes down below the specified value. And, A/C compressor bracket
and the oil dipstick tube are mounted on the oil pan.

10. FLYWHEEL AND DRIVE PLATE
1) DMF (Dual Mass Flywheel)
The dual mass flywheel, or DMF, eliminates excessive transmission gear rattle, reduces gear
change/shift effort, and increases fuel economy. There is a friction ring located between the inner and
outer flywheel that allows the inner and outer flywheel to slip. This feature is designed to alleviate any
damage to the transmission when torque loads exceed the vehicle rating of the transmission. The friction
ring is the weak spot in the system and can wear out if excessive engine torque loads are applied
through it. The system also has a center support bearing that carries the load between the inner and
outer flywheel, and is fitted with damper springs to absorb shocks.
2) Drive Plate
Drive plate receives the power from the start motor when starting the engine. With this, the drive plate
initially drives the power train system. And, it is connected to the torque converter to transfer the engine
torque to the power train system.Components ▶
