    摘要: A system for a sequential turbocharger includes a mode selection module, a feed-forward selection module, and a control loop module. The mode selection module generates a control mode signal based on an engine speed signal, an engine torque signal, and an engine mode signal. The control mode signal indicates one of an open-loop control mode and a closed-loop control mode. The feed-forward selection module determines a feed-forward value based on the control mode signal, the engine speed signal, and the engine torque signal. The control loop module determines a loop control value at least one of based on the feed-forward value, a variable geometry turbine (VGT) control signal, and an error signal; and based on a bypass valve (BPV) control signal and the error signal when the control mode signal transitions from the open-loop control mode to the closed-loop control mode.

    摘要: A method and control system for controlling the idle speed of an engine includes an engine speed module that generates an engine speed signal. The control system also includes an actuator control module that regulates an engine speed based on a desired idle speed when an engine idle mode is enabled and a balancing module that balances torque produced by cylinders of an engine based on the engine speed signal when the engine idle mode is enabled. The control module also includes an idle speed reduction module that determines an idle speed reduction based on the actual torques produced by the cylinders after the balancing module balances the torque and that decreases the desired idle speed based on the idle speed reduction.

    摘要: An engine assembly may include a voltage source and an oxygen pump assembly. The oxygen pump assembly may include an intake conduit and an oxygen pumping mechanism. The intake conduit may be in fluid communication with an air supply and an intake manifold. The oxygen pumping mechanism may include an oxygen ion conducting cell, a first electrode in electrical communication with the voltage source and a second electrode in electrical communication with the voltage source. The first electrode may be disposed on a first side of the cell and may be exposed to an interior of the intake conduit. The second electrode may be disposed on a second side of the cell and isolated from the interior of the conduit. The oxygen pumping mechanism may remove oxygen from an air flow within the interior of the intake conduit based on a voltage applied across the cell by the voltage source.

    摘要: A partial pressure determination module: determines a first partial pressure of oxygen in an intake manifold of an engine based on an output of a first oxygen sensor measuring oxygen in the intake manifold; and determines a second partial pressure of oxygen in an exhaust system based on an output of a second oxygen sensor measuring oxygen in the exhaust system. A concentration determination module: determines a concentration of oxygen in the intake manifold based on the first partial pressure and an intake manifold; and determines a concentration of oxygen in the exhaust system based on the second partial pressure. A flowrate determination module determines a mass flowrate of exhaust gas recirculation (EGR) based on the concentration of oxygen in the intake manifold and the concentration of oxygen in the exhaust system. An actuator control module controls an engine operating parameter based on the mass flowrate of EGR.
