As one embodiment, a method for an engine includes firing all cylinders of the engine and not altering the closing timing of the intake valves when fueling demands are greater than a threshold. The method further includes skip-firing the engine when fueling demands are less than a threshold, and holding open the intake valves of skipped cylinders for a greater duration than intake valves of firing cylinders.

Abstract: A method of operating an engine is provided. Output of an engine speed sensor, a mass air flow sensor, an exhaust gas temperature sensor, and an engine torque estimator are monitored with an electronic control module. It is determined if the engine is operating in one of either a transient condition and a non-transient condition based upon output of at least one of the sensors and the torque estimator. Fuel injection timing is set based upon if the engine is operating in a transient condition. An exhaust gas recirculation valve position is set upon if the engine is operating in a transient condition. An intake throttle position is set based upon if the engine is operating in a transient condition. The fuel injection timing, exhaust gas recirculation valve position, and the intake throttle position are set to minimize NOx emissions when the engine is operating in a transient condition.

Abstract: A regeneration disable control system (22) of a vehicle having a power take off device (10) that is run off a motor (12) which is powered by at least one battery (14), and an engine (16) for recharging the at least one battery and for regenerating a diesel particulate filter (20), includes a hybrid controller (18). The hybrid controller (18) sends a signal to an engine controller (21) to indicate whether hybrid-PTO mode is enabled. If the hybrid-PTO mode is enabled, the engine controller (21) determines whether regeneration of the diesel particulate filter (20) is required. If regeneration is required, the engine controller (21) sends a signal to a regeneration inhibitor (30) to disable the engine (16) from initiating a regeneration event.

Abstract: The method for regeneration of a diesel particulate filter of a vehicle equipped with a hybrid engine, wherein the temperature of the exhaust exiting the diesel engine is increased above a predetermined level by increasing load thereon, through optimization of interaction between the diesel particulate filter aftertreatment system and the hybrid engine control through messaging via a communication bus is disclosed. The load on the engine may be increased with or without the assistance of the electric motor/generator of the hybrid engine, and will not affect required acceleration/deceleration of the vehicle.
