Abstract: Systems, methods and apparatus are disclosed for providing reduced engine start times for a fumigation type internal combustion engine. A bypass is provided that directly connects the air-fuel mixer upstream of the compressor to the intake manifold, providing the air-fuel mixture to the intake manifold during engine startup.

Abstract: The present disclosure provides an engine fueling system that includes multiple fueling valves such that the fuel transport delay can be reduced. The fueling system may also include an electrically driven compressor to improve engine properties during engine startup. For example, an engine fueling system comprising: a first compressor; an intake air throttle operably coupled to the first compressor and positioned downstream of the first compressor; a primary fuel path in communication with a fuel supply, wherein a first fuel from the fuel supply is injected into the primary fuel path upstream from the compressor; and a secondary fuel path in communication with the fuel supply, wherein a second fuel from the fuel supply is injected into the secondary fuel path downstream from the compressor.
