摘要： An engine having a cylinder, a piston slideably received in the cylinder, a crankshaft connected to the piston, and a multi-link piston crank mechanism. The multi-link piston crank mechanism controls movement of the piston such that an acceleration of the piston at top dead center is less than an acceleration of the piston at bottom dead center. A determining device determines an operating condition of the engine. A combustion mode control device controls the engine to operate at an air-fuel ratio leaner than a stoichiometric air-fuel ratio when the determining device determines that the operating condition of the engine is in a predetermined operating region.

摘要： A variable compression ratio mechanism for a reciprocating engine includes upper and lower links linking a piston pin to a crankpin, an eccentric cam equipped control shaft and a control link cooperating with each other to vary the attitude of the upper and lower links. A control-shaft actuator is provided to vary a compression ratio. The actuator includes a reciprocating block slider linked at a front end to the control shaft, and a rotary member being in meshed-engagement with the rear end of the slider by a meshing pair of screw-threaded portions. A hydraulic modulator has a hydraulic pressure chamber facing the rear end face of the slider, so that working-fluid pressure in the pressure chamber forces the slider in the same axial direction as the direction of action of reciprocating load acting on the slider owing to combustion load.

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： A variable compression ratio mechanism that changes the compression ratio according to the rotation angle of a control shaft, wherein a stopper is provided at the highest compression ratio side for regulating the rotation of the control shaft. Then, the output detected by a compression ratio sensor for detecting the rotation angle of the control shaft when the stopper is in an abutted state is read. An adjustment value is learned in order to revise the sensor output based on the detected output.

摘要： A variable compression ratio mechanism for a reciprocating internal combustion engine includes upper and lower links mechanically linking a piston pin of a piston to a crankpin, and a control link mechanically linking the lower link to an eccentric cam of a control shaft. Also provided is a control-shaft actuator capable of continuously reducing a compression ratio by driving the control shaft in a first rotational direction and of continuously increasing the compression ratio by driving the control shaft in a second rotational direction opposite to the first rotational direction, so that the compression ratio is controlled to a low value in accordance with an increase in engine speed and/or engine load. A distance from the center of the control shaft to a centerline of the control link, measured with the piston near top dead center, is dimensioned so that the distance continuously decreases as the compression ratio decreases.
