摘要： An electromagnetic valve unit in an internal combustion engine is controlled by determining a difference between the output of a displacement sensor when a valve head is in an open position and the output of the displacement sensor when the valve head is in a closed position in each period of an opening and closing action of the valve head. The difference corresponds to a full displacement of the valve head between the open position and the closed position. The electromagnetic valve unit is also controlled by establishing, using the difference, a threshold for the output of the displacement sensor which corresponds to a predetermined displaced position of the valve head which is determined based on a proportion of the full displacement, and controlling energization of the valve-opening electromagnet and/or the valve-closing electromagnet depending on whether the output of the displacement sensor has reached the threshold or not upon the opening and closing action of the valve head immediately after the threshold is established.
摘要翻译：内燃机中的电磁阀单元通过在阀头处于打开位置时确定位移传感器的输出与位移传感器的输出之间的差值来控制，当阀头在每个周期中处于关闭位置时阀头的打开和关闭动作。该差异对应于阀头在打开位置和关闭位置之间的完全位移。电磁阀单元也通过使用该差异来建立位移传感器的输出的阈值来控制，所述阈值对应于基于全位移的比例确定的阀头的预定位移位置，并且控制通电开阀电磁体和/或闭阀电磁体取决于位移传感器的输出是否在阈值建立之后阀头的打开和关闭动作达到阈值。

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： A variable stroke characteristic engine 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 a hydraulic actuator (AC) that drives the control shaft (65) to thus make the stroke travel of the piston (11) variable, in which the hydraulic actuator (AC) is formed from a housing (HU), a cover member covering an aperture of the housing (HU), a vane case provided integrally within the housing (HU), and a vane shaft (66) housed within the vane case, and the vane shaft (66) is formed integrally with the control shaft (65). The number of components of the actuator (AC) can be decreased, and its ease of assembly can be improved.
