Abstract: An engine misfire detection device is mounted on a hybrid electric vehicle that includes an internal combustion engine and a generator. The internal combustion engine has a plurality of cylinders and a crankshaft and is dedicated to power generation. The generator is connected to the crankshaft via a torsional damper. The engine misfire detection device includes a generator rotation angle sensor and a processor. The generator rotation angle sensor detects the rotation angle of the generator rotating shaft. The processor is configured to execute a misfire detection process. The misfire detection process includes a first misfire detection process of determining that the internal combustion engine has misfired when an amplitude correlation value that correlates with the magnitude of amplitude of rotation speed of the generator rotating shaft and is detected by the generator rotation angle sensor is greater than a determination threshold value.

Abstract: A torsional vibration damping device that prevents an increase in an inertial torque due to resonance without reducing a mass of an inertial mass member. A torque of an engine is delivered to a first rotary element of a planetary unit. The torsional vibration damping device damps pulsation of the torque of the engine to be delivered to the transmission by an inertial torque generated by a rotation of the third rotary element resulting from a relative rotation between the first rotary element and the second rotary element caused by the pulsation of the engine torque. The torsional vibration damping device comprises: a connection member rotated integrally with the first rotary element; an intermediate member rotated integrally with the second rotary element; an output member delivering torque to the transmission; a first elastic member connecting the connection member to the intermediate member; and a second elastic member connecting the intermediate member to the output member.

Abstract: A torsional vibration damper in which a mass may be fitted easily into a chamber is provided. In the rotary disc, an insertion hole is formed integrally with the chamber. An opening diameter of the insertion hole is larger than an outer diameter of a flange plate of the mass, and an opening width at a boundary between the insertion hole and the chamber is larger than an outer diameter of a trunk of the mass. The retainer comprises a restricting portion that restricts an oscillating range of the mass in the chamber.

Abstract: A torsional vibration damper in which noise and vibrations in a planetary gear unit are suppressed is provided. In a planetary gear unit, as an inertial element is oscillated to establish an inertial torque by a relative rotation between a sun gear and a ring gear. Pinion gears are interposed between the sun gear and the ring gear at predetermined intervals, and gear dimensions of one of the pinion gears and gear dimensions of another one of the pinion gears are different from each other.
