3. CHECK AND INSPECTION
1) Cylinder
(1) Compression pressure test
Specified value ▶
Compression ratio16.5 : 1
Test conditionat normal operating temperature (80˚C)
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. -

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.

2) Fuel System Flow Diagram
The fuel from the fuel tank is supplied to the fuel heater of fuel filter/priming pump and then low
pressure generated by the low pressure pump (built into HP pump) is transmitted to the HP pump.
The fuel pressure at the HP pump is controlled by the IMV valve, and the maximum allowed
pressure is 1,800 bar. The compressed fuel at the fuel pump is delivered to the rail, and injected by
the injectors according to the injection signals. The injection method is the same with the
conventional method; Fuel return by backleak which operates the needle valve.
The major difference is that the fuel return line is connected to the fuel filter inlet port, not the HP
pump venturi.
The pressure from the high pressure pump is increased to 1,800 bar from 1,600 bar, and the pump
is now installed to the cylinder head (cylinder block for previous model). The fuel pressure is
generated by the operation of intake camshaft and gears. The specifications for the IMV valve and
the fuel temperature sensor are not changed.
