(1) Compression pressure test
Specified value ▶
Compression ratio16.5 : 1
Test conditionat normal operating temperature (80˚C)
Compression pressur
eStandard32 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.

Disconnect the fuel rail pressure sensor connector to cut off the fuel injection.
Remove the air cleaner duct and glow plugs. -

-
Place the diagram sheet to compression
pressure tester and install it into the plug
hole. 1. 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. -

Components ▶
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.

(5) High Pressure System Pressure Test
Fuel rail pressure test ▶
Disconnect the pressure sensor connector
(A) and IMV connector (B) from the fuel
rail. 1.
Connect the pressure tester to the fuel rail
pressure sensor connector. 2.
Crank the engine 2 times for 5 seconds. 3.
Read the highest pressure value
displayed on the tester display.
If the highest pressure value is 1,050 bar
or less, refer to the section "Fuel System
Check Process". -

Static test for backleak of injector ▶
Disconnect the injector return hose and
cover the openings with caps shaped
screw (included in the special tool). 1.
Connect the hose of the container for
measuring backleak to the return nipple of
the injector.
(prevent air entry to the low pressure line) 2.
Disconnect the IMV connector of the
high pressure pump and then fuel
pressure sensor connector. 3.
The connector of the injector can be easily
contaminated. Always keep it clean.
Crank the engine 2 times for 5 seconds.
Check the time for flow if injector backleak
and confirm that it is within the specified
range. 4.
5.
If the value is out of the specified range,
replace the injector.
SpecificationBelow 20 sec.

HP pump pressure test ▶
Prepare a special tool for high pressure
test and clean it thoroughly to prevent
foreign materials from entering. 1.
Disconnect the high pressure fuel supply
pipe on the HP pump and install the close
rail in the tool kit. 2.
Connect the other end of the close rail to
the fuel rail for test. 3.
Disconnect the return hose for HP pump
and connect the clear hose and connect its
the other end to the return port of the fuel
rail for test. 4.
Connect the digital tester connector to the
sensor connector of the fuel rail for test.
Crank the engine 2 times for 5 seconds after
removing the IMV connector and fuel rail
pressure sensor connector.
Read the pressure value displayed on the
tester display is within the specified. 5.

1. OVERVIEW
The components in fuel system supply the fuel and generate the high pressure to inject the fuel to
each injector. They are controlled by the engine ECU.
The common rail fuel injection system consists of fuel tank, fuel line, low pressure line which
supplies low pressure fuel to the low pressure pump (including high pressure pump), common rail
which distributes and accumulates the high pressurized fuel from the fuel pump, high pressure
line which connected to the injector, and the engine control unit (ECU) which calculates the
accelerator pedal position and controls the overall performance of vehicle based on the input
signals from various sensors.
