Friction Losses between Piston Ring-Liner Assembly of Internal Combustion Engine: A Review
      Bedajangam S. K., Prof. N. P. Jadhav
Abstract: In IC engine piston ring friction losses account for approximately 20% of total mechanical losses as reported in the literature. A reduction in piston ring friction would therefore result in higher efficiency, lower fuel consumption and reduced emissions. To reduce these losses, various parametric approaches are made particularly at design stage and experimental level. The goal of this study was develop piston ring designs to improve engine efficiency, without adversely affecting oil consumption, blow by, wear and cost. Thus it provides characterization of a pressure balance in terms of effective area and distortion coefficient of the piston and cylinder. The models are for specific piston ring-liner system with different capacity. The variable parameters are piston velocity, engine speed, oil viscosity, gas pressure, crank angle film thickness and coefficient of friction. Non variable parameter are system constant, bore diameter, ring tension, ring width, compression ratio, reciprocating mass, piston ring area and piston ring profile. The major assumptions for developing models are either hydrodynamic lubrication theory or mixed lubrication theory of Reynolds equation.
