System outline
The high pressure injection system is designed to deliver a precise quantity of diesel fuel to the engine at a set
moment.
It is fitted with a BOSCH computer, type EDC16CP33.
The system comprises:
– a priming bulb,
– a diesel filter,
– a high pressure pump,
– a fuel pressure regulator (or actuator) on the high pressure pump (MPROP),
– a fuel pressure regulator (or actuator) mounted on the injector rail (DRV),
– an injector rail,
– a fuel pressure sensor,
– four piezoelectric injectors,
– a diesel temperature sensor,
– a coolant temperature sensor,
– an upstream air temperature sensor,
– a cylinder reference sensor,
– an engine speed sensor,
– a turbocharger pressure sensor,
– an exhaust gas recirculation valve,
– a recycled gas cooling solenoid valve,
– an accelerator pedal potentiometer,
– an atmospheric pressure sensor integrated into the injection computer,
– a flow sensor,
– a turbocharging limiter solenoid valve,
– a damper valve,
– a particle filter,
– a turbo upstream temperature sensor,
– a turbo upstream pressure sensor,
– a particle filter differential pressure sensor,
– a particle filter upstream temperature sensor,
– a particle filter downstream temperature sensor,
– an electric coolant pump (turbocharger),
– four thermoplungers.
The common rail direct high pressure injection system works sequentially (based on the petrol engine
multipoint injection).
This system uses piezoelectric injectors which enable a more precise injection since opening and closing times
are shorter compared to conventional solenoid injectors.
This injection system reduces operating noise, reduces the volume of pollutant gases and particles and produces
high engine torque at low engine speeds thanks to a pre-injection procedure.
The high pressure pump generates the high pressure and transmits it to the injector rail. The actuator located on
the pump controls the quantity of diesel supplied, according to the demand determined by the computer.
The rail supplies each injector through a steel pipe. The actuator located on the injector rail controls the pressure
of diesel fuel in the rail according to the demand determined by the computer.
