活塞润滑 meaning in English

piston lubrication

Abstract : in this paper , an analytical study of the dynamics of the piston in a reciprocating internal combustion engine is conducted . the equations of reynolds and moving of piston are derived . a useful method of solution is obtained . the method is applied to s1100 diesel engine . the results of this study indicate that piston oil film is found to be sensitive to the piston - cylinder bore clearance , the location of the wrist pin and lubricant viscosity
文摘:对往复式内燃机活塞的动力特性进行了分析研究,导出了活塞润滑的雷诺方程和活塞运动方程,给出了可供实用的求解方法,并采用这种计算方法对s1100柴油机进行了设计计算与试验研究.研究结果表明,活塞润滑油膜历程与活塞& &缸套的间隙、活塞销的位置、润滑油的粘度等因素密切相关
