FUEL INJECTION CONTROL
System DescriptionINFOID:0000000001162530
SYSTEM DESCRIPTION
The high pressure injection system is designed to deliver a precise quantity of diesel fuel to the engine at a set
moment. The Siemens VDO piezo Common Rail system used on the K9K Step 2 engine is a second genera-
tion Common Rail injection system. Fuel pressure in the rail can reach a maximum of 1,600 bar. It uses fuel
injectors controlled by piezoelectric actuators. The fuel is pressurised by means of a high pressure pump then
sent to a rail which supplies the four fuel injectors.
 The circuit comprises two subsystems, which are distinguished by the fuel pressure level:
- the low pressure circuit comprises the tank, the diesel fuel filter, the transfer pump and the fuel injector return
lines,
- the high-pressure circuit comprises the high-pressure (HP) pump, the rail, the fuel injectors and the high-
pressure (HP) pipes.
Finally, there are a number of control sensors and actuators which enable the entire system to be controlled
and monitored.
 The system comprises:
- Priming bulb
- Fuel filter
- High pressure supply pump
- Fuel rail
- Fuel rail pressure sensor
- Fuel injector
- Fuel pump temperature sensor
- Engine coolant temperature sensor
- Camshaft position sensor
- Crankshaft position sensor
- Turbocharger boost sensor
- EGR volume control valve control position sensor
- EGR volume control valve
- Barometric pressure sensor (built in ECM)
- Mass air flow sensor
- Intake air temperature sensor
- Electric throttle control actuator
High Pressure Supply Pump
The high pressure supply pump consists of the following components:
 Internal fuel transfer pump:
- This pump is a vane-type rotary pump. It draws in fuel from the fuel tank through a fuel filter and supplies the
high pressure pump with fuel.
 Volumetric control valve:
- This solenoid valve regulates the flow of fuel entering the high pressure pump and enables an optimum
quantity of fuel to be pressurised according to operating phase; this improves the output of the high pressure
supply pump and thereby the output of the engine as well.
 High pressure pump:
- This pump is a 3-piston radial pump, it generates the required pressure in the rail.
 Pressure control valve:
- This solenoid valve regulates the output pressure of the high pressure pump.
Fuel Injector (Piezo Type)
CAUTION:
The fuel injector voltage is very high (much higher than that of conventional fuel injectors). This volt-
age can be as much as 150 V.
The piezo fuel injectors enable rapid, precise metering of the quantity of fuel injected, with excellent injection
process repetitivity.
The piezo actuator operates like a capacitor. To control the fuel injector, the computer sends, at the correct
time, a quantity of energy which is sufficient to enable the actuator to deform and the fuel injector to open.
During the injection period, the piezo actuator stores this energy.
At the end of the injection period, the computer recovers the energy sent at the start of the control operation.
The piezo actuator discharges and returns to its original shape. The fuel injector closes. To improve output, the

ENGINE ASSEMBLY
 If items or work required are not covered by the engine section, follow the procedures in the applica-
ble sections.
 Always use the support point specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
 For supporting points for lifting and jacking point at rear axle, refer to GI-48, "
Garage Jack and
Safety Stand and 2-Pole Lift".
