Abstract:
1. An arrangement for controlling an internal combustion engine having a cylinder with a combustion chamber and comprising: an electronic engine control unit ( 1 ), a fuel injector ( 2 ) for the injection of fuel into the combustion chamber, connecting lines ( 3 ) extending between the electronic engine control unit ( 1 ) and the injector ( 2 ) with an injector needle ( 16 ), and an intelligent electronic block ( 4 ) forming with the injector ( 2 ) a component unit ( 5 ), said electronic block ( 4 ) comprising an electronic data storage device ( 6 ) for the storage of data, a computing unit ( 7 ), an energy storage device ( 9 ) for storing electric energy and for supplying energy to the electronic block ( 4 ) during operation of the internal combustion engine in injection pauses, and also a measuring unit ( 8 ) for detecting the movement of the injector needle ( 16 ) by way of an inductive or capacitive measuring procedure and transmitting measuring signals to the engine control unit ( 1 ) via the connecting lines ( 3 ) during the injection pauses while the electronic block ( 4 ) is energized by the energy storage device ( 9 ).
