    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.

    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: A base determination module determines a base value based on a base value input. A compensation determination module determines a base compensation value based on a base value input. A compensation coefficient determination module determines a compensation coefficient based on a compensation coefficient input. A multiplier module determines a compensation value based on a product of the base compensation value and the compensation coefficient. A target module determines a target value based on the base value and the compensation value and controls an actuator based on the target value. A calibration module selectively displays predetermined options for calibrating one of the base compensation value input and the compensation coefficient input and sets the one of the base compensation value input and the compensation coefficient input to a selected one of the predetermined options.

    摘要: An intake control system comprises an estimation module and a turbocharger control module. The estimation module receives one of a first pressure within an intake manifold measured by a manifold pressure sensor and a second pressure measured by a pressure sensor at a location between a compressed air charge cooler and a throttle valve. The estimation module estimates the other one of the first and second pressures based on the received one of the first and second pressures. The turbocharger control module controls output of a turbocharger based on the estimate of the other one of the first and second pressures.
