ABSTRACT:
A system for electronically detecting the transient state of engine operation of an internal combustion engine having a spark ignition system. A measuring circuit counts pulses having the pulse separation of the ignition timing of the spark ignition system and produces data output. A plurality of memorizing circuits are provided for memorizing old data output from the measuring circuit and a subtractor compares the old data output and the memorizing circuit with the new data output from the measuring circuit and produces the difference between the data and the amount of the difference. The output of the subtractor is used for correcting the air-fuel ratio of the air-fuel mixture of an emission control system using a three-way catalytic converter.
