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 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 lower link for an engine piston crank mechanism includes first and second half members joined by bolts to form a crankpin bearing portion. The first half member includes a first pin boss portion to connect the lower link with a first link which is one of an upper link connected with a piston and a control link having one end mounted swingably on the engine. The second half member includes a second pin boss portion to connect the lower link with a second link which is the other of the upper link and the control link, and an internally threaded portion into which one bolt is screwed. The second half member further includes a load transfer portion which is made greater in rigidity than the internally threaded portion.

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.
