Power Part Parameters Affecting Lube Oil Consumption and Blowby in Small Bore, High Speed Diesels 690752

Ten series of fractional factorial tests for oil consumption on nine small bore, high speed diesel engines have revealed favorable factors for top, intermediate, and oil rings, pistons, and liners that may be used in the initial design of a diesel engine. Blowby is much less affected by these factors, and so the factors may be chosen for oil control with but little penalty to blowby control. An enormous amount of additional work is necessary to refine further the parameters tested and to investigate new parameters.
