    • A piston and piston ring assembly has a compression ring and a compression ring groove configured to allow proper mating between the two following thermal expansion. The groove is provided with a substantially horizontal lower face. The ring has a bottom surface that is contoured to provide a cross-sectional angle that substantially matches the anticipated deflection of the lower face caused by thermal expansion. Thus, when the piston expands due to temperature changes associated with operating the internal combustion engine, the lower face deflects away from the combustion chamber. The deflection is absorbed by the pre-contoured bottom surface of the ring. Thus, localized high points between the piston ring and the piston ring groove are reduced and the friction originating at such locations is also reduced. Accordingly, the ring and the groove experience reduced friction and reduced wear while the sealing function of the compression ring is enhanced.
    • 活塞和活塞环组件具有压缩环和压缩环槽,所述压缩环和压缩环槽被配置成允许在两个随后的热膨胀之间适当配合。 槽设置有大致水平的下表面。 环具有底部表面,该底部表面具有轮廓,以提供基本上匹配由热膨胀引起的下表面的预期挠曲的横截面角度。 因此,当活塞由于与操作内燃机的温度变化而膨胀时,下表面偏离燃烧室。 偏转由环的预轮廓底表面吸收。 因此,活塞环和活塞环槽之间的局部高点减小,并且在这些位置产生的摩擦力也降低。 因此,当压缩环的密封功能增强时,环和凹槽经历减小的摩擦并减少磨损。
