    摘要： A variable stroke characteristic engine is provided in which a piston (11) and a crankshaft (30) are linked to a control shaft (65) via a variable stroke link mechanism (LV), and the variable stroke link mechanism (LV) is operated by an actuator (AC) that drives the control shaft (65) to thus make the stroke travel of the piston (11) variable, wherein a housing (HU) of the hydraulic actuator (AC) for operating the variable stroke link mechanism (LV) is provided in a bearing member (54) of a lower block (41) supporting the crankshaft (30), and the housing (HU) is thus made small, thereby suppressing any increase in the dimensions of the engine. Furthermore, a hydraulic switching valve unit (92) for controlling operation of the hydraulic actuator (AC) is directly mounted on the housing (HU), thereby enhancing the responsiveness of the hydraulic actuator (AC).

    摘要： In a variable stroke engine comprising a plurality of links (60, 61) connecting a piston (11) with a crankshaft (30), a control member (65) disposed on an engine main body so as to be moveable in two directions over a prescribed range relative to the engine main body, a control link (63) connecting one of the plurality of links with the control member and an actuator (AC) for displacing the control member, the actuator comprises a ratchet mechanism that utilizes a force transmitted from the piston to the control member as an actuating force for the control member. By providing a spring member (73, SP, 121) that applies a biasing force to the control member, an appropriate actuating force can be applied to the control member in either direction.

    摘要： In a variable stroke-characteristic engine for a vehicle, a control shaft and a control link are disposed on a front side of a vehicle body with respect to a crankshaft. An actuator for driving the control shaft is disposed on an outer surface of an engine block on the front side of the vehicle body. Thus, the actuator projects as much as possible from a position of the engine block toward the front side of the vehicle body so that traveling wind from ahead of the vehicle is effectively applied to the actuator to enhance the cooling effect. Hence, any temperature increase of the actuator is suppressed. Moreover, the actuator is disposed as far as possible from an exhaust manifold that is heated to a high temperature by the heat of an exhaust gas.

    摘要： Secondary vibration generated accompanying reciprocation of a piston (21) of a multi-link variable compression ratio engine (E) can be eliminated effectively, even when the direction of the secondary vibration is inclined relative to a cylinder axis (L1), by inclining the direction (shown by arrow) of an excitation force generated by a secondary balancer system (43) so that it coincides with the direction of the secondary vibration. The secondary balancer system (43) is formed by supporting balancer weights (44a, 45a) on a pair of balancer shafts (44, 45) rotating in directions opposite to each other, and by displacing the phases of these balancer weights (44a, 45a) the direction of the excitation force generated can be inclined so as to coincide with the direction of secondary vibration of the engine (E).
