Abstract: A control system for an engine includes first and second modules. The first module estimates a total amount of exhaust gas recirculation (EGR) in the engine, wherein the total amount of EGR includes (i) EGR within cylinders of the engine and (ii) EGR flowing through an EGR system of the engine. The second module selectively controls an overlap of intake and exhaust valve timing in the engine based on (i) a position of an EGR valve in the EGR system and (ii) a comparison of the estimated total amount of EGR in the engine and an EGR threshold.

Abstract: Techniques for learning endstop position(s) of an actuator for a wastegate valve include detecting a learn condition and, in response to detecting the learn condition, performing a learn procedure for the actuator endstop position(s). The learn procedure includes commanding the actuator to a desired position past the endstop position corresponding to a fully-closed wastegate valve while rate-limiting a velocity of the actuator. When the difference reaches its maximum allowed value and the velocity falls below a fraction of its rate limit, the endstop position is learned. When the wastegate valve is requested open, the actuator is then controlled using the learned endstop position. Reference stiffness for a fully-closed wastegate valve could be obtained, and subsequent stiffness checks could then be periodically performed and, if less than the reference stiffness, a duty cycle of the actuator could be increased during open-loop control.

Abstract: A technique is provided for compensating an untrimmed oxygen (O2) sensor utilized in operation of an exhaust gas recalculation (EGR) system associated with an engine. The technique includes, in one implementation, receiving a measurement from the O2 sensor at a known pressure, where the O2 sensor is positioned on an intake side of an engine system. Humidity compensation and pressure compensation are then determined for the O2 sensor measurement, where the pressure compensation is based in part on the humidity compensation. The EGR system is controlled using the untrimmed O2 sensor measurement that has been compensated for pressure and humidity.

Abstract: An integrated inlet manifold tuning valve for a variable configuration air inlet manifold and a charge motion control system. A tuning valve, which is preferably approximately a quarter-barrel valve, is arranged at an end of the low- and high-speed runners at or near an intake port for an internal combustion engine. The tuning valve operates to tune the variable manifold and provide a mixture motion for charge motion control.
