Combustion pressure boost in the cylinder of modern diesel engines increases the loads acting on the piston pin bearings and lubrication of the piston pin bearings becomes a serious problem. Using a piston pin with an eccentric center of gravity solves this problem. This article deals with the phenomenon of parametric resonant oscillations of the piston pin during the reciprocating motion of the piston. The purpose of the study is to use a phenomenon that increases the amplitude of the oscillations and, consequently, the sliding speed in the relative rotational movement of the piston pin.

偏心重心的活塞销的振动

现代柴油发动机的气缸中的燃烧增压增加了作用在活塞销轴承上的负荷，并且活塞销轴承的润​​滑成为一个严重的问题。使用偏心重心的活塞销可以解决此问题。本文讨论了在活塞往复运动期间活塞销的参数共振现象。该研究的目的是使用一种现象，该现象会增加振荡的幅度，从而增加活塞销相对旋转运动中的滑动速度。
