Abstract (en)
[origin: DE19918095C1] The circuit includes at least one set-down controller (2,3) with an output stage for each electromagnet of the valves (5,6), for controlling the valves based on time control signals. The current flowing in the electromagnets is controlled according to valve position signals. A digital communication computer (1) evaluates a crank-shaft position signal, exchanges data with an engine operation controller (9) via a communication link (8), and produces the time control signals for the set-down controller based on the crank-shaft position signal and the data received from the engine operation controller.
