Abstract:
1. A method of controlling a diesel engine of a vehicle, the method comprising: providing a control module operable to control the diesel engine; sensing a speed of the diesel engine; closing a throttle of the diesel engine to prevent oxygen from entering an intake manifold of the diesel engine when the sensed speed of the diesel engine is equal to or greater than a maximum allowable engine speed; and actuating an Exhaust Gas Recirculation (EGR) valve to regulate circulation of exhaust gas from the diesel engine through the intake manifold to control pressure within the intake manifold when the throttle is closed in response to the sensed speed of the diesel engine being equal to or greater than the maximum allowable engine speed; wherein actuating the EGR valve includes modulating the EGR valve to maintain the pressure in the intake manifold above a minimum allowable pressure limit.
