    • A multi link type piston-crank mechanism comprises an upper link that has one end pivotally connected to a piston of the engine through a piston pin, a lower link that is pivotally connected to the other end of the upper link through an upper pin and rotatably disposed on a crank pin of a crankshaft of the engine; and a control link that has a base end part swingably held by a body of the engine and a leading end pivotally connected to the lower link through a control pin. An axis of the piston pin is offset relative to an axis of the piston in thrust and counter thrust directions. When the piston comes to BDC, a part of the piston takes a position below a lower edge of a corresponding cylinder of the engine and the upper pin is offset relative to the axis of the piston pin in the same direction as a pin offset direction in which the axis of the piston pin is offset in the thrust and counter thrust directions relative to the axis of the piston.
    • 多连杆式活塞曲柄机构包括上连杆,其一端通过活塞销枢转地连接到发动机的活塞,下连杆通过上销以可转动的方式连接到上连杆的另一端 设置在发动机的曲轴的曲柄销上; 以及控制连杆,其具有由发动机的主体可摆动地保持的基端部和通过控制销可枢转地连接到下连杆的前端。 活塞销的轴线在推力和反推力方向上相对于活塞的轴线偏移。 当活塞到达BDC时,活塞的一部分位于发动机的相应气缸的下边缘的下方,并且上销相对于活塞销的轴线在与销偏移方向相同的方向上偏移 活塞销的轴线相对于活塞的轴线在推力和反向推力方向上偏移。

    • 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.
    • 用于发动机活塞曲柄机构的下连杆包括通过螺栓连接以形成曲柄销轴承部分的第一和第二半部件。 第一半构件包括第一销凸台部分,用于将下连杆与作为与活塞连接的上连杆之一的第一连杆和具有可摆动地安装在发动机上的一端的控制连杆连接。 第二半构件包括第二销凸台部分,用于将下连杆与作为上连杆和控制连杆中的另一个的第二连杆连接,以及内螺纹部分,一螺栓被拧入其中。 第二半部件还包括负载传递部分,该部分的刚度大于内螺纹部分。

    • 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.
