Abstract: When the vehicle is stopped and removal of deposits is not required, and forced charging of a power storage device is not being performed, the controller controls the fuel supply device so that a supply fuel pressure is at the first fuel pressure. When the vehicle is stopped and the removal of deposits is required, and the forced charging of the power storage device is being performed, the controller controls the fuel supply device so that the supply fuel pressure is at a second fuel pressure higher than the first fuel pressure. When the vehicle is stopped and the removal of deposits is required, and the forced charging of the power storage device is not being performed, the controller controls the fuel supply device so that the supply fuel pressure is at a third fuel pressure higher than the first fuel pressure and lower than the second fuel pressure.

Abstract: A hydrogen fueled powerplant including an internal combustion engine that drives a motor-generator, and has a two-stage turbocharger, for an aircraft. A control system controls the operation of the motor-generator to maintain the engine at a speed selected based on controlling the engine equivalence ratio. The control system controls an afterburner, an intercooler and an aftercooler to maximize powerplant efficiency. The afterburner also adds power to the turbochargers during high-altitude restarts. The turbochargers also include motor-generators that extract excess power from the exhaust.

Abstract: A control system for a machine having an engine, a first alternator, a second alternator, and an aftertreatment system is disclosed. The control system may include a sensor associated with the aftertreatment system and configured to determine a temperature of exhaust passing through the aftertreatment system, and a controller in communication with the sensor and connectable to the first and second alternators. The controller may be configured to determine an available power output of the first alternator, determine a load increase of the engine needed to raise the temperature of the exhaust to an operating temperature of the aftertreatment system, and selectively connect the first alternator to a power consumer to achieve the load increase when the available power output of the first alternator is greater than the load increase. The controller may be further configured to selectively connect the second alternator to the power consumer to achieve the load increase when the available power output of the first alternator is less than the load increase.

Abstract: A control device of a multi-cylinder engine is provided. The device includes first and second auxiliary components. The first auxiliary component generates energy. The device includes an angular speed variation detecting device for detecting an angular speed variation of a crankshaft, and an auxiliary component control device for controlling drive loads of the first and second auxiliary components. When an engine load is low and the angular speed variation exceeds a predetermined threshold, the auxiliary component control device increases a total drive load of the auxiliary components. Here, if the drive load of the first auxiliary component is increasable, the drive load of the first auxiliary component is increased, and when this increase amount is insufficient, the drive load of the second auxiliary component is increased, whereas if the drive load of the first auxiliary component is not increasable, the drive load of the second auxiliary component is increased.
