| Variable stroke injection pump | BOSCH: 0.82±0.02 mm | When equipped with a LUCAS high-pressure fuel pump: there is an X mark on the accelerator cable lever |
| Idle speed | 825±25 | |
| Maximum number of revolutions (without/with load) | 5200±100/4600±100 (Fuel injection pump BOSCH) 5000±100/4350±100 (Fuel injection pump LUCAS) | |
| Injector injection pressure | 125 - 138 bar | |
| Glow plugs | BOSCH or BERU | Voltage is about 15A after 8 seconds of warming up |
| Fuel filter | With manual bleed lever for air removal and heater from flowing coolant |
Technical characteristics of the F9Q direct injection diesel engine
A 4/11 E2000R672 distributor-type fuel injection pump is used with an electronic control unit that controls the pump, the cold engine start system, and the exhaust gas recirculation valve.
Fuel injection pump adjustment:
Installation at TDC using a pin with a diameter of 8 mm. The piston stroke is 0.45±0.02 mm.
The nozzle is double-spring, resistance at 20°C = 100±10 Ohm.
High pressure fuel lines:
- length = 360 mm;
- inner diameter = 1.8 mm.
EGR solenoid valve:
- supply voltage = 12 V;
- resistance 5.5±0.5 Ohm.
Glow plugs:
- BOSCH. CHAMPION or BERU;
- tightening torque = 15 Nm;
- supply voltage = 12 V;
- resistance = 1.1±0.1 Ohm.
Air mass flow meter: BOSCH or SIEMENS with film as a heating element.

Accelerator drive via a stepper motor on the high-pressure fuel pump. Potentiometer on the accelerator pedal to determine its position. Electric heating of the coolant to accelerate engine warm-up to the optimum operating temperature and increase the heater output when heating the passenger compartment.
