Installation for the digital-electronic control of inlet, exhaustion and injection valves as well as of the injection in internal combustion engines

A control installation for the digital-electronic control of at least one of valve means and ignition means in internal combustion engines, in which the valve means are electromagnetically actuated and the respective crankshaft position is adapted to be determined digitally, characterized in that it comprises control circuit means including a fixed value storage means in which at least for one cylinder of the engine, at least one of opening and closing points of time of the valve means, on the one hand, and ignition points of time, on the other, are operable to be at least partially stored and selected as digital values coordinated to the respective operating conditions and corresponding to a predetermined crankshaft position in the form of data sets, storage register means for each stored value of a data set operatively connected to the fixed value storage means;

• the stored value being transferable to the storage register means, pulse comparison means for each value of a data set operatively connected to the storage register means, in which a value is adapted to be compared with the respective crankshaft position and which is operable to produce a commencing pulse in case of agreement of the two values, and a follower pulse generator means at least for each value of a data set operatively connected with the respective comparison means in which, beginning and together with the commencing pulse, a number of pulses corresponding to the number of cylinders is produced, uniformly distributed over a predetermined number of degrees of the crankshaft, and means for feeding the last-mentioned pulses to at least one of valve actuating means and ignition means of the associated cylinder in a sequence corresponding to the ignition sequence.
