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： Joining surfaces (2a, 2b) of a pair of conductive joining members (1a, 1b) to be joined to each other are caused to face each other, and while one of the joining members (1a, 1b) is slid relative to the other of the joining members (1a, 1b), a current is passed from one of the joining members (1a, 1b) to the other of the joining members (1a, 1b) so as to cause resistance heating. Abrasion, plastic flow, and material diffusion therefore occur in high surface-pressure sections of the joining surfaces (2a, 2b), and the joining surfaces (2a, 2b) are joined together while current concentration locations are varied from moment to moment.

摘要： In a reciprocating piston engine employing a variable compression ratio mechanism linked to a reciprocating piston for variably adjusting a geometrical compression ratio by varying at least a piston top dead center position, so that the top dead center position obtained at a low geometrical compression ratio is set to be lower than that at a high geometrical compression ratio, responsively to a controlled variable, a controller is configured to set a target compression ratio to a high value at low engine load operation, and to a relatively low value at high engine load operation. A substantially entire area of a crown of the piston, defining a part of a wall surface of a combustion chamber, is formed of a non-metallic material having a higher heat-insulating and heat-reserving property as compared to a base structural material of each of the combustion chamber and 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： A piston crank mechanism has an upper link coupled to a piston by a piston pin, a lower link having a crankpin journal, wherein the crankpin journal is coupled to a crankpin of a crankshaft and is coupled to the upper link by an upper pin, and a control link is coupled to an eccentric cam of a control shaft that is supported by an engine block and coupled to a control pin boss by a control pin. The crankpin journal of the lower link is arranged and dimensioned relative to the upper pin such that a projection area defined by projecting the width of the upper pin along a direction line passing through a center of the piston pin and a center of the upper pin does not obscure an area defined by the crankpin during operation of the crankshaft as viewed in an axial direction of the crankpin.

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.
