4. CHECK AND INSPECTION
1) Cylinder
(1) Compression pressure test
Specified value
Compression ratio
16.5 : 1
Test condition
Compression pressureStandard32 bar
Minimum18 bar
Differential limit between cylindersMaximum 3 bar
The compression pressure test is to check the conditions of internal components (piston, piston ring,
intake and exhaust vale, cylinder head gasket). This test provides current engine operating status.
Before cranking the engine, make sure that the test wiring, tools and persons are keeping away from
moving components of engine (e.g., belt and cooling fan).
Park the vehicle on the level ground and apply the parking brake.
Do not allow anybody to be in front of the vehicle. -
-
-
(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 Specified value
Whole engine below 25%
at valve and cylinder head gasket below 10%
at piston ring below 20%

Exhaust valve
Measure the cylinder head height "A". 1.
If the height is less than the limit, the cylinder
head must be replaced. -
Insert the valves into the valve guides and
measure the recesses. 2.
If the measured value is out of the specified
range, machine the valve seat as much as
necessary until the specified value is
achieved. -

Intake manifold
4. INTAKE/EXHAUST SYSTEM
1) Intake Manifold
Intake manifold is installed on the cylinder head with 8 bolts. The variable swirl valve is introduced to
improve the EGR gas mixture and turbulence in combustion chamber and to decrease the exhaust gas.
2) Exhaust Manifold
Exhaust manifold is installed on the cylinder head with 10 stud bolts and nuts. EGR port is integrated in
cylinder head.Components

6. CYLINDER HEAD
Cylinder head contains cam position sensor, vacuum pump, intake manifold, exhaust manifold and valve
assembly. Vacuum pump and the high pressure (HP) pump are driven by Camshaft and valves are
install in vertical direction. This enables the compact layout in cylinder head assembly.

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.

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.
