Abstract: Provided is a control apparatus for an internal combustion engine that can suppress blowback of in-cylinder residual gas to an intake passage when reverting from a fuel-cut operation accompanied by valve stopping control of an intake valve while suppressing an oil ascent during execution of the fuel-cut operation, and a control apparatus for a vehicle equipped with the internal combustion engine. When executing a fuel-cut operation accompanied by intake valve stopping control, advancement control of the opening/closing timing of an exhaust valve (32) is executed. If the advancement control is being executed in a case where a request to revert from the fuel-cut operation has been detected, an advance amount of the opening/closing timing of the exhaust valve (32) is retarded so as to become less than or equal to a predetermined value.

Abstract: A managing device having a simple structure for an umbilical member or a conduit and a robot having the managing device, by which an interference region of the conduit is reduced as much as possible and the undesirable excess length of the conduit may be cancelled without using an auxiliary device. A first conduit supporting member is arranged on an upper arm of the robot and a second conduit supporting member is arranged on a wrist element of the robot. The conduit is fixed to or twistably supported by the first and second supporting member. Further, the conduit is held by a holding member, mounted between the first and second supporting member, in particular, adjacent to the side of a forearm of the robot, such that the conduit may slide relative to the holding member and may rotate about axes along and perpendicular to the sliding direction of the conduit. As the holding member is positioned as close to the forearm as possible, a gap between the conduit and the forearm is reduced and the possibility of interference between the conduit and an external equipment may be minimized.

Abstract: A variable valve actuation apparatus for an internal combustion engine includes a first link arm which has a projected portion that is engageable with and disengageable from a guide rail, and which is displaceable in the axis direction of a camshaft, and a link shaft linked to the first link arm in such a manner as to allow rotation but constrain movement in the axis direction. When an electro-magnetic solenoid is electrified, the first link arm rotates about the link shaft so that the projected portion engages with the guide rail. In association with the displacement of the link arms that occurs during the engagement, the state of motion of second rocker arms changes, so that the opening characteristic of valves provided for each cylinder is switched.

Abstract: The present invention makes it possible to favorably change valve-opening characteristics of a valve using a simplified configuration without leading to an increase in the number of components and also without causing an increase of friction due to sliding, in a valve operating apparatus for an internal combustion engine in which the valve-opening characteristics of the valve are variable. A changeover mechanism for switching the connection/disconnection of rocker arms disposed between cams and a valve is provided. When a slide pin reaches a displacement end in the retreating direction of changeover pin, the biasing force of a return spring acting on changeover pins is received by an engaging part between a notch part provided in the slide pin and a lock pin in a state separated from a camshaft.

Abstract: Provided is a variable valve operating apparatus for an internal combustion engine, which can switch, based on an actuation of a single actuator, operating characteristics of valves for a plurality of cylinders collectively and smoothly using a rigid member, while suppressing an increase in wear of a guide rail and reducing the number of delay mechanisms.A changeover mechanism to switch operating characteristics of valves for each cylinder of first and second cylinder groups is provided. The changeover mechanism includes link shafts as a rigid member which is displaced when being engaged with a helical guide rail as a result of the actuation of an electromagnetic solenoid. The changeover mechanism includes a delay mechanism, which delays the displacement of the second link shaft in a cylinder in which the valves are lifting when the electromagnetic solenoid is actuated, at some point in the link shafts between the first cylinder group and the second cylinder group.
