Abstract

A control system for a multi- cylinder internal combustion engine comprises an engine speed detector (20) and an engine power detector (38). Dependent on the detected speed and power as compared with predetermined reference levels either all or half the fuel injectors 1-1 to 1-6 are intermittently energised, the power is determined as a function of the pulse width of the injector energisation signals. The speed reference level with which the detected engine speed is compared may be varied dependent on the detection of low power output of the engine, Fig. 4 (not shown). <IMAGE>
