Abstract: An engine control system of a vehicle includes a first temperature module, a second temperature module, and an exhaust gas recirculation (EGR) control module. The first temperature module determines a temperature of gas within an intake manifold of an engine. The second temperature module determines a temperature of an EGR conduit that is coupled to the intake manifold. The EGR control module reduces opening of an EGR valve when the temperature of the gas and the temperature of the conduit is greater than a predetermined temperature.

Abstract: An engine control system for an auto-stop/start vehicle includes an auto-stop/start module that generates an auto-stop command for shutting down an engine while an ignition is ON and subsequently generates an auto-start command for re-starting the engine. The system includes an actuator control module that disables an engine load, parks exhaust and intake cam phasers, disables fuel, sets a first throttle opening, monitors a crankshaft rotational position, speed, and deceleration, sets a second throttle opening for a predetermined duration if a piston simultaneously crosses a target position below a target engine speed and below a target degrees of rotation remaining, sets a third throttle opening, and determines if an engine speed is below a threshold speed before setting a fourth throttle opening when the engine speed is below the threshold speed, and causes the piston to rest in a predetermined position range.

Abstract: An engine control system for a vehicle includes a shutdown control module that generates a command to shut down an engine of the vehicle when at least one of: a driver requests the shutdown of the engine via an ignition system; and when one or more predetermined conditions are satisfied for shutting down the engine without the driver requesting shutdown of the engine via the ignition system. A valve control module, when the command to shut down the engine is generated, advances an exhaust camshaft phaser based on a predetermined exhaust park position. When the exhaust camshaft phaser is in the predetermined exhaust park position, an exhaust valve of a cylinder is fully closed during an exhaust stroke of the cylinder before a piston of the cylinder reaches a topmost position for a next intake stroke of the cylinder.

Abstract: A first target module determines a first target output pressure of an engine oil pump based on a speed of the engine oil pump and an oil temperature. A second target module, based on a runtime period of an engine, sets a second target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A third target module, based on an engine load, sets a third target output pressure of the engine oil pump to one of greater than and equal to the first target output pressure. A selection module selects one of the second and third target output pressures, sets a selected target output pressure based on the selected one of the second and third target output pressures, and controls displacement of the engine oil pump based on the selected target output pressure.

Abstract: A method for cold start emissions diagnostic of a catalytic treatment device of an internal combustion engine includes determining a torque reserve; determining a catalyst light off (CLO) state; integrating the total torque reserve over a time period established by the CLO state; determining if a value from the integration exceeds an integration threshold; and if the value from the integration exceeds the integration threshold, indicating that the cold start emissions diagnostic is positive.
