G0701-3-4 Simultaneous and Approximate Analyses of Engine Bearings : Consideration of Balance

Abstract

In this paper, it is clarified by using simultaneous bearing analysis that effects of balance weight on performance such as journal orbits of piston pin boss bearings and small end bearings & big end bearings of connecting rod are small as compared with result of main bearings. The four new approximate analyses considering balance weight are proposed for main bearings and influences of balance weight on main bearings are shown in good agreements of results by simultaneous analysis. Engine bearing analyses considering balance weight are established.
