Fanner, J C; Snyder, W E

An improved method is described of fuel control for a gaseous fueled internal combustion engine that includes a prechamber for combustion chambers, an ignition system for igniting the fuel, and an intake manifold connected with each combustion. The improved method described here comprises: supplying fuel gas to the prechambers at a pressure not less than intake manifold pressure; simultaneously supplying a fuel gas and air mixture to the combustion chambers; igniting the gas in the prechambers to ignite the gas and air mixture in the combustion chamber; supplying a fuel gas and air mixture to the prechambers at a pressure higher than the pressure of the fuel gas initially supplied thereby stopping flow of fuel gas alone to the prechambers; varying the pressure of the fuel gas and air mixture in accordance with the intake manifold pressure; and simultaneously controlling the mixture of fuel gas and air supplied to the prechambers.
