Tendency Analysis of Lube Oil Degradation in Internal Combustion Engine

摘要

Through systematically monitoring some internal combustion engines, the author has given various tendency graphs of lube oil degradation and their mathematical model. Moreover, a theoretical analysis of this change tendency has also been penetrated with qualitative analysis of ferrography and partial terms of physical-chemistry. There is directive signficance on judging degree of lube oil degradaton and controlling the time of oil changes strictly.
