ABSTRACT:
A speed governing system for an internal combustion engine includes an internal combustion engine having an inlet manifold, an exhaust manifold, and at least one variable volume combustion chamber disposed therebetween. The apparatus also includes a fuel and air delivery control system having an air delivery mechanism responsive to a sensor control signal for affecting engine operation, a fuel delivery mechanism responsive to input from an operator for affecting engine operation, and a sensor responsive to engine operating conditions for supplying the sensor control signal. The apparatus also has an exhaust gas recirculation system including an exhaust gas recirculation conduit and an exhaust gas recirculation control valve, the control valve being controllably regulated in response to the sensor control signal in order to adjust air/fuel ratio. A method for governing operating speed of an internal combustion engine is also disclosed.
