Abstract: A rotating electrical machine capable of obtaining a higher torque while limiting the amount of permanent magnets used. A magnetic pole of a rotor includes an auxiliary magnet embedded in a rotor core and at least one main magnet arranged on an outer circumferential side than the auxiliary magnet of the rotor. In each magnetic pole, the distance from an end of the main magnet, the end facing the auxiliary magnet, to the auxiliary magnet facing the main magnet is shorter than the length of the main magnet in the radial direction. In a cross-section orthogonal to the rotation axis of the rotating electrical machine, the main magnets of each magnetic pole are arranged so as to be asymmetrical about a virtual line passing the rotation axis and axisymmetrically dividing the auxiliary magnet,

Abstract: A control device determines an operation amount of an actuator that regulates an intake air amount, on the basis of operation conditions of an internal combustion engine. The control device is configured to calculate an index value of a piston temperature of the internal combustion engine, and correct the operation amount to an operation amount that increases the intake air amount, when the calculated index value is a value corresponding to a higher temperature of the piston temperature than a threshold value of the index value corresponding to an upper limit threshold value of the piston temperature, at a time of deceleration in which an engine speed of the internal combustion engine decreases. As the index value, for example, the piston temperature which is estimated from a deviation between an inputted heat amount and a heat release amount of a piston can be used.

Abstract: A control device for an internal combustion engine according to the present invention (the present device) changes the combustion state of air fuel mixture such that if at least the load on the engine 10 falls within the range between a first threshold value Pem1 and a second threshold value Pem2, a heat release rate gravity center position Gc is equal to a given crank angle θa independent of an engine load, or if the engine load falls within the range beyond the second threshold value Pem2, the heat release rate gravity center position Gc is changed to a value on a retarded angle side in a range closer to the retarded angle side than the given crank angle θa as the engine load is increased. A combustion state is changed by, for example, one or more of combustion parameters such as a main injection period of fuel, a fuel injection pressure (common-rail injection system pressure), the injection quantity, the timing, and the number of times of pilot injection, a turbocharging pressure, and an EGR amount.

Abstract: A control apparatus is provided, which controls combustion state such that the Heat Release Rate Barycentric Position (Gc) coincides with the Target Barycentric Position (Gc*), and which can prevent an increase in the combustion noise caused by an increase in an ignition lag which occurs in a case where an EGR apparatus is in execution, and, a rotational speed is low or an engine load is low. The control apparatus (ECU70) prevents the increase in the ignition lag by increasing a supercharging pressure of a supercharger (44) which the engine (10) is equipped with, thus, it prevents the increase in the combustion noise.
