Abstract

The engine (1) has an evaluator (7) and control (10) supplied with engine operating data including the momentary relative angular position of the crankshaft for correspondingly regulating the ignition timing and/or the air/fuel ratio. The regulated factor varies for successive operating cycles about a required value. The induced pressure within each cylinder is also measured by sensors (5) a mean value obtained for each operating stroke using the piston positions represented by the values for the crankshaft angle. A sequence of mean values is registered and successive values compared. The variation in the regulated operating factor is halted and the setting at this point held when the mean induced pressure reaches a max. value.
