摘要： A multi-link engine has a piston that moves inside a cylinder. A piston pin connects the piston to an upper link, which is connected to a lower link. A crank pin of a crankshaft supports the lower link thereon. The lower link is pivotally connected to one end of a control link, which is connected at another end to the engine block body by a control shaft. The control shaft is lower than a crank journal of the crankshaft, and disposed on a first side of a plane that is parallel to a cylinder center axis and that contains a center rotational axis of the crank journal. The cylinder center axis is located on a second (i.e., opposite the first side) plane. The control link has a center axis that is parallel to the cylinder center axis when the piston is near top and bottom dead centers.

摘要： A bonding method includes bonding a pair of members together made of conductive material and having bonding surfaces which are not positioned on the same plane. In the bonding method, the bonding surfaces of the members to be bonded are positioned to face each other, an electric current is supplied from one of the members to be bonded to the other for carrying out resistance heating while the pair of members to be bonded are slid relative to each other. In this way, the bonding surfaces are bonded to each other. Split or partition surfaces that form a hollow passage and extending along the axis of the hollow passage are set as the bonding surfaces which are not on the same plane.

摘要： A multi link type piston-crank mechanism comprises an upper link that has one end pivotally connected to a piston of the engine through a piston pin, a lower link that is pivotally connected to the other end of the upper link through an upper pin and rotatably disposed on a crank pin of a crankshaft of the engine; and a control link that has a base end part swingably held by a body of the engine and a leading end pivotally connected to the lower link through a control pin. An axis of the piston pin is offset relative to an axis of the piston in thrust and counter thrust directions. When the piston comes to BDC, a part of the piston takes a position below a lower edge of a corresponding cylinder of the engine and the upper pin is offset relative to the axis of the piston pin in the same direction as a pin offset direction in which the axis of the piston pin is offset in the thrust and counter thrust directions relative to the axis of the piston.

摘要： A piston-crank mechanism links crankpins of a crankshaft with piston pins of pistons by using a plurality of links. The piston-crank mechanism allows an upward inertia force produced near a top dead center of each piston to be smaller than a downward inertia force produced near a bottom dead center of the piston in order to reduce secondary vibration occurring during operation. In a four-cycle inline four-cylinder internal combustion engine, a total force of inertia forces exerted from adjacent cylinders to each of second and fourth crankshaft bearings becomes a downward force, which reinforces a downward force produced in response to combustion pressure. These second and fourth crankshaft bearings have a rigidity higher than the remaining crankshaft bearings.

摘要： In a lash adjuster of a valve gear which employs a serration-shaped thread mechanism, the formation of a tribochemical reactive film is suppressed by using as the materials for its adjuster screw and nut member (or the materials for their thread surfaces) materials that, even if FM oil is used, the friction coefficient will not extremely decrease. The nut member is provided on the underside of an end plate of a lifter body. The adjuster screw is threadedly engaged in a threaded hole of the nut member. The adjuster screw is biased by a return spring. The female threads of the threaded hole and the male threads of the adjuster screw are serration shaped. One or both of the nut member and the adjuster screw, or the pressured thread surfaces of one or both of them, are formed of a material that will not react with oil additives of FM oil to suppress the formation of tribochemical reactive film, thereby stabilizing the operation of the lash adjuster.

摘要： In a crankshaft of an internal combustion engine wherein a crankthrow is shortened by the use of a multi-link mechanism, the crankthrow from the axis of a main journal to the axis of a crankpin is set shorter than one-half of a piston stroke, and an oil passage is formed to supply lubricating oil to a bearing portion of the crankpin. The pin-side opening of the oil passage, which is open at the outer peripheral surface of the crankpin, is formed in ranges other than angular ranges of 0°, 90°, 180°, and 270° with respect to a reference line extending from the axis of the main journal toward the axis of the crankpin in a decentering direction of the crankpin, thereby alleviating a stress concentration caused by a torsional torque in the vicinity of the pin-side opening of the oil passage.
