An engine operation timing control includes a transducer producing pulses at predetermined different angular positions of the engine shaft, a speed counter connected to the transducer and periodically generating a multibit digital signal corresponding to the speed of the engine, a programmed read only memory device addressed by the speed counter providing a digital output identifying the transducer pulse appropriate to commence the operation at the existing speed, and counter means for periodically causing commencement of said operation in synchronism with respective ones of the transducer pulses, said memory device being connected to said counter means to vary the phase of said counter means relative to shaft position. |
