Claim 17:
18. A system, comprising:
an internal combustion engine including an intake system with an air-fuel mixer, the air fuel mixer connected to an intake manifold of the internal combustion engine by compressor flow path that includes a compressor and an intake throttle, the intake system further including a compressor bypass flow path that includes a bypass valve and connects the air-fuel mixer with the intake manifold, wherein the compressor bypass flow path bypasses the compressor and the intake throttle; and
an electronic controller configured to control the bypass valve and the intake throttle and, in response to an engine startup condition, the controller is configured to open the compressor bypass valve and close the intake throttle to direct an air-fuel mixture from the air-fuel mixer directly to the intake manifold through the compressor bypass flow path.
