A Simplified Piston Secondary Motion Model Considering the Dynamic and Static Deformation of Piston Skirt and Cylinder Bore in Internal Combustion Engines 2008-01-1612
A dry piston secondary dynamics model has been developed. This model includes the detailed piston and cylinder bore hot shape geometries, and piston deformations due to combustion pressure, axial inertia and interaction with the cylinder bore, but neglects the effects of the hydrodynamic lubrication at the piston - cylinder bore interface in order to achieve faster calculation times. The piston - cylinder bore friction is calculated using a user supplied friction coefficient. This model provides a very useful, fast tool for power cylinder system analysis, provided its limitations are understood.
