Abstract: The internal combustion engine comprises: operating members and operating by a predetermined pressure or more of oil pressure; a hydraulic oil path supplying hydraulic oil to the operating members through crank journals; a lubricating oil path supplying lubricating oil to crankpins through the crank journals; a hydraulic control valve linearly controlling an oil pressure supplied to the operating members due to change of that opening degree; and a control device. The control device controls the opening degree of the hydraulic control valve so that when operating the operating members, the predetermined pressure or more of oil pressure is supplied to the operating members, and controls the opening degree of the hydraulic control valve so that when not operating the operating members, less than the predetermined pressure of oil pressure is supplied to the operating members.

Abstract: A variable length connecting rod includes a connecting rod body, an eccentric member, a switching mechanism and a stopping mechanism. The eccentric member is provided at a small diameter end of the connecting rod body. The eccentric member rotates such that an effective length of the variable length connecting rod is varied. The switching mechanism includes a hydraulic piston connected to the eccentric member. The eccentric member reaches a first position when the switching mechanism is in a first state. The eccentric member reaches a second position when the switching mechanism is in a second state. The stopping mechanism includes a stopping member that abuts against or engages with the eccentric member or the hydraulic piston such that the eccentric member is maintained at an intermediate position between the first position and the second position.

Abstract: An internal combustion engine includes: a head cover covering a cylinder head; and a variable valve actuation mechanism. The variable valve actuation mechanism includes: a cam placed inside the head cover and rotating with a camshaft extending in a rotation axis direction; and an intermediate arm placed inside the head cover and sandwiched between the cam and a rocker arm. A pair of side through-holes, which are provided for a support rod supporting the intermediate arm to pass through, are formed in side portions of the head cover so as to face each other along the rotation axis direction.

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 variable length connecting rod comprises a connecting rod body, an eccentric member, a hydraulic cylinder, a hydraulic piston, a check valve, a switching mechanism and a hydraulic mechanism. The check valve permits a flow of hydraulic oil from a primary side of the check valve to a secondary side of the check valve and prohibits the flow from the secondary side to the primary side. The switching mechanism comprises a single switching pin. The connecting rod body is formed with first to fourth oil paths. The switching pin is switched between a first position making the first oil path communicate with the fourth oil path and making the second oil path communicate with the third oil path, and a second position making the first oil path communicate with the third oil path and making the second oil path communicate with the fourth oil path.
