Abstract
An electric control system for controlling an internal combustion engine, which comprises sensor means for detecting at least one of operating condition of the engine and ambient condition in the vicinity of the engine to generate an output continuously variable with a change in the above at least one condition, comparator means for comparing the output of the sensor means with upper and lower limits which are set at values lying slightly beyond a normal range of values indicative of the at least one condition which can exist during normal operation of the engine, and generating a first signal when the output of the sensor means lies beyond the upper limit or the lower limit; and a timer arranged to generate a second signal is continuously generated over a predetermined period of time. The electric control system includes an air/fuel ratio control system for internal combustion engines.
