ABSTRACT:
The air fuel ratio control systems described for controlling the air fuel mixture being supplied to the prechamber of gaseous fueled, internal combustion engines includes a pressure control regulator that is responsive to inlet manifold pressure to assure that the pressure of the fuel supplied to the prechamber is as desired and includes volume flow control valves arranged in the air conduit and in the fuel conduit for providing the desired air fuel ratio. Further, the system may include controls for providing relatively rich fuel mixtures or fuel only to the prechambers at certain phases of operation of the engine.
