ABSTRACT:
A control system for an internal combustion engine has an ignition timing control device and a combustion duration control device such as a mixture controller. Sensors detect the start and end of combustion which are compared with a look-up table of target values for the engine speed and load to provide error signals. The processed error signals provide corrections which are added to base values from look-up tables of ignition timing and mixture and supplied to the control devices so as to tend to eliminate the error signals, so that the engine runs with its designed start of combustion and combustion duration values.
