Abstract: An engine starter inertia drive that includes a torque transmission level control mechanism is presented. Such torque transmission level control is provided by removing the variations in clutch plate compression force conventionally introduced by the shock absorbing meshing spring of the engine starter inertia drive. This is accomplished by repositioning the compression forces such that they are contradicted by a combination of the meshing spring force and the frame reaction of the engine starter. In this way, variations in the meshing spring force are compensated by equal and opposite variations in the frame reaction force to maintain the clutch plates in position. Preferably, a single wave spring is used to provide the pressure spring force on the clutch plates.

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.
