Abstract

In an internal combustion engine (10), the combustion process is controlled by successively adjusting a variable quantity e.g. ignition timing, fuel supply, in dependence upon the instantaneous values of two different parameters e.g. map, rpm, subject to limitations dependent upon the portion of the operating range of the engine. Memory 18 stores values of the quantity corresponding to the values of the parameters. Memory 19 stores limiting values for the variable quantity in different parts of the operating range. Unit 22 forwards the output of memory 18 if it is within the limiting value, otherwise the output of memory 19 is forwarded. An adjustment for fuel type can be provided by unit 21. A knock sensor can be used to modify the contents of memory 19 by means of unit 28. The unit 28 can alternatively respond to undesirable levels of CO in the exhaust or engine temperature to modify the contents of memory 19. <IMAGE>
