ABSTRACT:
A process for intermittent control of a cyclically operating internal combustion engine wherein, in the succession of working cycles, working strokes are skipped--in approximately uniform distribution--and the number of skips is varied in dependence on the load. Fuel is fed in a controlled fashion only to the nonskipping working chambers of the internal combustion engine independently of the load in a constant quantity optimal for consumption. For a sensitive power distribution, especially in the low load range, the number of skips is varied chronologically at least approximately randomly and independently of the speed, i.e., the temporal density of the working strokes is varied. This can be accomplished by setting differently finely staggered firing patterns or by a stochastic ignition setting.
