Electronic control device for single-cylinder or multicylinder autoignition reciprocating internal combustion engines/motors, wherein fuel is suppliable to the given combustion space by use of an injection valve and an injection pump, the injection pump exhibiting a control rod by displacement of which the fuel injection quantity is changeable, an actuator controlled by a control unit further engaging with the control rod, and the control unit being in operative connection with engine sensors, pickups and/or further actuators and, if and to the extent provided, with service (e.g., vehicle) pickups and/or displays and/or controls and/or actuators via inputs and outputs. The representation of a modular concept with a wide range of variation is to are changeable via the number and/or the allocation and/or the signal mode of the inputs and/or outputs.

Electronic control device

A fuel injection system, especially for air-compressing, spontaneous ignition reciprocating piston internal combustion engines. At least one parameter which characterizes the injection process, such as beginning and duration of the injection, is adapted to be regulated by at least one electromagnetic control valve per cylinder unit which can be controlled by an electrically operating data processor as a function of characteristic operating parameters of the internal combustion engine. In order to compensate for transmission deviations of the electromagnetic control valves caused by wear and operation, the control pulses of the data processor are transmitted to each electromagnetic control valve via a suitable circuit in such a way that the control valve opens and/or closes with a constant time delay during each control procedure. The constant time delay of the control valve can be established as a function of the actual speed of the internal combustion engine. The control time point of the control valve, as determined by the data processor, for opening and/or closing the control valve can be varied as a function of the constant time delay thereof.
