    • An improved connecting rod assembly for a reciprocating internal combustion engine provides essentially simple harmonic linear motion of a piston, thereby eliminating forces and moments caused by non-simple harmonic linear motion of a piston. The connecting rod assembly of the present invention maintains a uniform distance between a crank pin and a piston. Essentially simple harmonic piston motion also increases engine efficiency by reducing the amount of negative work which results from detonation before top dead center. The connecting rod assembly may include a first member rotatably connected to a crankshaft and having two connection points each spaced a distance A/2 from the crankshaft connection, and second and third members having a length C, arranged in a crossing relationship, and connecting respective ones of the connection points of the first member to respective ones of two connection points on a piston, the piston connection points being spaced apart by a distance B. In one embodiment, the ratios A:B:C are 2:4:5.
    • 用于往复式内燃机的改进的连杆组件提供活塞的基本上简单的谐波直线运动,从而消除由活塞的非简单谐波直线运动引起的力和力矩。 本发明的连杆组件保持曲柄销和活塞之间的均匀距离。 基本上简单的谐波活塞运动也可以通过减少在上止点之前引爆的负作用量来提高发动机效率。 连杆组件可以包括可旋转地连接到曲轴的第一构件,并且具有两个与曲轴连接件间隔开A / 2的连接点,以及具有以交叉关系布置的长度C的第二和第三构件, 第一构件的连接点与活塞上的两个连接点中的相应连接点的一个连接点,活塞连接点间隔开距离B.在一个实施例中,比率A:B:C为2:4:5。
