ABSTRACT:
A feedback control system for maintaining the air/fuel ratio in a two-cycle internal combustion engine employing an oxygen sensor that senses the combustion products in a combustion chamber at the end of the combustion cycle. The feedback control system is discontinued when a misfire condition exists and the fuel amount supplied is decreased until the misfired condition subsides and then feedback control is returned.
