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： An actuator is connected to one of components forming a power transmitting device capable of transmitting a power provided by a valve operating cam provided on a cam shaft, so that the actuator can drive an engine valve in a lift amount which is obtained by addition of a lift amount of the engine valve based on a cam profile of the valve operating cam and a lift amount of the engine valve based on the operation of the actuator. Thus, a portion of the lift amount of the engine valve is borne by the valve operating cam, whereby a valve-opening power borne by the actuator can be reduced, as compared with a system designed so that the engine valve is driven by only the actuator only. The amount of electric power consumed by the actuator can be smaller.
摘要翻译： 致动器连接到形成能够传递由设置在凸轮轴上的阀操作凸轮提供的动力的动力传递装置中的一个部件，使得致动器能够以提升量驱动发动机气门，该提升量通过添加 基于致动器的操作，基于气门操作凸轮的凸轮轮廓和发动机气门的升程量的发动机气门的提升量。 因此，发动机气门的提升量的一部分由阀操作凸轮承担，由此与被设计为使发动机气门仅被驱动的发动机气门驱动的系统相比，由致动器承受的开阀功率可以减小 执行器。 致动器消耗的电力量可以更小。
