ABSTRACT:
A feedback control system for an internal combustion engine that includes an arrangement for determining when the output of the fuel-air ratio sensor may not be desirable for main engine control, and switches between an open control and a feedback control in response to those conditions. In addition, transitional running is improved when operating after long predetermined low-speed running so as to result in a quicker return to the desired fuel-air ratio.
