    摘要: A method of controlling a diesel engine includes sensing a speed of the diesel engine, and closing a throttle of the diesel engine when the sensed speed of the diesel engine is equal to or greater than a maximum allowable engine speed to prevent oxygen from entering an intake manifold of the diesel engine, thereby preventing combustion and stopping the operation of the diesel engine. An Exhaust Gas Recirculation (EGR) valve is actuated to regulate circulation of exhaust gas from the diesel engine through the intake manifold to control pressure within the intake manifold to prevent damage to other engine components from excessive positive or negative pressure.

    摘要: An engine control system comprises an engine speed control module and an idle limiting module. The engine speed control module selectively controls an engine based on an idle speed request. The idle limiting module selectively reduces the idle speed request by an amount that is based on a wheel slip value.

    摘要: A method for controlling an exhaust-braking engine maneuver includes driving a compressor by a turbine so that the compressor receives and compresses an intake stream of fluid to produce a stream of compressed fluid. The method also includes receiving a stream of engine working fluid that includes the stream of compressed fluid, and discharging, to an exhaust system, an exhaust stream comprising the stream of engine working fluid. A stream of scavenged exhaust fluid comprising at least a portion of the exhaust stream is received, and work is extracted from the stream of scavenged exhaust fluid by the turbine to drive the compressor. The variable turbine nozzle and an intake throttle valve are modulated so as to satisfy one or more turbine control criterion and one or more compressor control criterion.

    摘要: A control system for an engine that includes a turbocharger includes a restriction estimation module and an engine protection module. The restriction estimation module estimates restriction of airflow through an air filter of the engine based on a comparison between measured and modeled temperatures at an outlet of a compressor of the turbocharger. The engine protection module, based on the estimated airflow restriction, at least one of controls turbocharger boost, controls turbocharger airflow, controls a fueling rate of the engine, and generates a warning signal for a driver of a vehicle.
