Abstract The e~~icient use and speci~ic ~ue1 consumption of I.C.E’S represent one o~ the most important problems ~acing the operator and the mechanical engineer •. These depend basicly on the optimum per~ormance of the engine, which may be considered satis~actory i~ [2,17J The exhau.s;t smoke is ~’ot excessive. There are no breakdowns caused by the failure o~ components in service •. Durability. i.e. maximum practical running time between two successive overhauls-and parts replacements-is as long as possible. The WEAR RATE is su~~iciently low. - Adhesive-, corrosive-. and Abrasive wear are the most commenly types o~ wear met with in I.C.E’S. The abrasive wear i~ the most decisive ~actor in determining the li~e of l.e.E’S [11J, and is directly connected to the problems of engine filt- ration. There~oret the identical engines have dif~erent life- time depending on whether these engines are used in the desert, in agriculture area, in the city or in high ways [5,16J. There is only one way to diminish the abrasive wear caused by the contaminants and wear particles; it is the FILTRATION which serves ~or reducing the quantities o~ contaminants getting into the system from the environment and for removing particles from the lubricating oil [3J.
