Abstract: A pendulum vibration damper in which a retainer is prevented from being moved or tilted in an axial direction. In the pendulum vibration damper, a restriction member formed on any one of the retainer and an inner face of the casing to be brought into contact to the other one of the retainer and the inner face of the casing when the retainer is moved or tilted in an axial direction of the rotary disc. A clearance between the casing and the rolling mass in the axial direction is shorter than a thickness of the retainer in the axial direction.

Abstract: A hybrid vehicle having a pendulum damper in which resonance at around an idling speed of an engine can be prevented to improve N.V. performance. The hybrid vehicle comprises an engine and at least one motor. In the hybrid vehicle, a power transmission path is formed between the engine and drive wheels. In the power transmission path, a pendulum damper is disposed to suppress torsional vibrations, and a disconnecting clutch is disposed to selectively interrupt power transmission between the engine and the pendulum damper.

Abstract: A torsional vibration damper having improved vibration damping performance. The torsional vibration damper comprising: a pendulum vibration damper that damps pulsation of engine torque by an oscillating motion of an inertia body in response to the pulsation of the torque; and an engagement device that damps the amplitude of the pulsation of the engine torque by a relative rotation of rotary members. The pendulum vibration damper and the engagement device are arranged in order on a transmission route of the torque of the engine from a side at which the engine is disposed.

Abstract: A torsional vibration damper that can reduce collision noise of an inertia body when a rotary member is stopped, and a control device therefore. In the torsional vibration damper, a rotary member is mounted on an output shaft of an engine such that none of rolling masses is situated within a predetermined angle range above a rotational center axis of the rotary member when the engine is stopped. Therefore, when the engine is stopped, the inertia body will not be supported by only one of the rolling masses situated within the predetermined angle range.

Abstract: A torsional vibration damper whose vibration damping performance will not be reduced in a high speed range. In the torsional vibration damper, a planetary gear is oscillated within a first oscillating range when a torsional torque is smaller than a reference torque, and within a second oscillating range when the torsional torque is greater than the reference torque. Each backlash between the pinion gear and at least one of a sun gear and a ring gear within the second oscillating range is individually wider than each backlash between the pinion gear and the sun gear and each backlash between the pinion gear and the ring gear within the first oscillating range.

Abstract: A torsional vibration damper in which collision noise resulting from collision of a rolling member against a rotary member is reduced. The torsional vibration damper comprises a restriction mechanism that establishes a restriction force in a direction to restrict the relative rotation between the rotary member and the inertia body, when the rolling member centrifugally pushed onto a raceway surface is pushed radially inwardly by the raceway surface toward a radially inner limit position of a guide section.

Abstract: An apparatus for controlling an internal combustion engine is provided. An engine includes a compression release mechanism and a fuel injection valve. The compression release mechanism variably controls the opening degree of a valve member, and thereby connects the combustion chamber of the engine with at least one of the intake passage and the exhaust passage in order to release in-cylinder pressure during at least the compression stroke. A controller controls the fuel injection valve to execute coasting with the fuel cut off in which the fuel is cut off under a predetermined condition, and while executing coasting with the fuel cut off, controls the compression release mechanism to increase the opening degree of the valve member of the compression release mechanism as the speed of the engine is higher.

Abstract: A vehicle having a valve stop mode control unit configured such that an intake valve and an exhaust valve are stopped in a closed state during rotation of an output shaft, supply of fuel to an engine is stopped, a clutch is made to be in an engaged state, and pistons are driven by rotational forces from driving wheels through the output shaft. When there is a request for valve stop inertial running, a negative pressure is supplied to an intake passage by a vacuum pump.

Abstract: The present invention relates to an internal combustion engine. An object of the invention is to allow an effect produced by are anodic oxide film to be exerted while suppressing a decrease in the combustion rate. A piston 10 includes a cavity portion 20 and a tapered portion 26 that is formed so as to surround the cavity portion 20 on an outer side thereof. The diameter of the tapered portion 26 decreases progressively in the downward direction from the top face side of the piston. A squish portion 28 is formed on an outer side of the tapered portion 26. An anodic oxide film 30 is formed on a surface (tapered face) of the tapered portion 26 and a surface (squish face) of the squish portion 28. The anodic oxide film 30 is not formed on the surface (cavity face) of the cavity portion 20.

Abstract: A torsional vibration damper includes a planetary rotary unit and an elastic body that couples two rotary elements of three rotary elements so that the two rotary elements can rotate relatively to each other. The torsional vibration damper includes a shaft supporting member by which a rotation center axis of at least any one rotary element of the two rotary elements and a rotation center axis of the rotary element other than the planetary rotary unit and the two rotary elements are held on the same axis. The shaft supporting member has a holding section that is disposed in a position between fellow planetary rotary elements and not making contact with the planetary rotary elements and that fits with and thereby suppresses movement of the rotary element other than the planetary rotary unit and the two rotary elements in the axial direction.
