"Proposed work utilizes three existing fourth-generation modules of the cylinder kit model which applied to improving oil consumption, blowby and general engine life in gasoline and diesel engines for over thirty years. When completed, the proposed Phase 1work will:,h Link the three independent modules:- Ring motion, gas flow, oil film thickness, and friction- Calculation of void areas between ring face and non-round cylinder- Piston motion including resultant contact forces between skirt, lands, cylinder wall, oil film formation between skirt/cylinder bore, and total friction loss,h Develop and integrate the following modules into the above program:- Ring conformability and twist created by ring design/operating forces- Oil transport/movement as influenced by cylinder bore surface character/values- Initial wear module ring/liner surfacesThe above integrated modules will permit:- Calculation of oil film between ring face and cylinder bore in three dimensions- Predicted values for blow-by, positive and reverse flows- Friction loss caused by piston ring/piston- Wear of ring face and cylinder boreconsidering piston, ring, bore geometry/finish and engine operating conditions. Substantial reduction in cost of commercial or military diesel engines"
