ABSTRACT:
An air-fuel ratio controller for a gaseous-fueled, turbocharged engine having an air manifold, a gas manifold, and a turbine inlet is disclosed herein. The controller includes means for controlling air manifold pressure and means for controlling turbine inlet temperature. The means for controlling air manifold pressure includes means for providing an air manifold pressure set point signal based on gas manifold pressure and engine RPM's and at least one constant input. The means for controlling turbine inlet temperature includes means for modulating the slope of the set point signal for the air manifold pressure controller.
