Abstract

A control system is provided for controlling the composition of a gas and fuel mixture supplied to an internal combustion engine. The output of an engine roughness detector (spark ignition engine) or an exhaust smoke detector (compression ignition engine) is compared with a limit value to provide a correction to a base value of mixture composition from a look up table. The magnitude of the correction is limited to a predetermined value and the corrected base value controls the composition of the mixture supplied to the engine.
