ABSTRACT:
A system for controlling engine air/fuel ratio includes an engine, a compressor having an inlet receiving air. The compressor discharges air to the engine intake. A recirculation path is provided from the compressor discharge to the compressor inlet. A controllable valve is located along the recirculation path. A controller is programmed to control the valve to vary the air flow to the engine intake, thereby controlling the air/fuel ratio. Various applications for the compressor recirculation arrangement are possible.
