ABSTRACT:
A method is described for operating a gaseous fueled engine, where gaseous fuel and intake air are delivered to a first intake port of a cylinder of the engine and intake air without gaseous fuel is delivered to a second intake port of the cylinder, the first port separated from the second port. Further, the method includes inducting the fuel and intake air from the first port via a first intake valve, and the intake air from the second port via a second intake valve, into the cylinder, where the first intake valve is opened after the second intake valve.
