The engine control unit „MR-PLD“ (pump-line-nozzle system) controls the electronic Diesel-fuel injection and is also designed for the engine series 450, 500 and 900. The main function of the control unit is the exact electric control of the solenoid valves at the injector valves. Regarding this, the optimum start of injection and the necessary injection quantity for the torque (or the desired speed in the case of a PTO speed control operation) demanded by the control unit on the engine side, are calculated and set (mapping specific, through measured engine and ambient conditions).
The control unit also provides further features like fault recognition, possibility of limp-home operating modes, diagnosis and interfaces with other control systems
The module MR-PLD engine electronics consists of the control unit and the fuel cooling. The MR-PLD control unit consists of a component circuit board with base plate (planar technique) and a zinc pressure die casting housing. The circuit board/base plate combination is screwed to the housing.
The seal between housing and circuit board is achieved by means of a fluid gasket.
The external electrical contact is maintained via a 16 pin and a 55-pin socket. To bring the pressure inside the housing into equilibrium with the ambient pressure, a pressure sensitive membrane is located on the bottom of the housing. The housing has 4 eyelets to accommodate the damping elements and screw them onto the engine.
