A Numerical Analysis of the Interaction between the Piston Oil-Film and the Elastic Structure in an Internal Combustion Engine

Abstract:

The piston secondary motion significantly influences the tribologicalcharacteristics in an internal combustion engine, such as the piston slapphenomenon and the frictional power loss.An analytical treatment was conducted to investigate piston motion and a computer program was written to predict optimum designs for high mechanical efficiency. This paper focuses on an analysis of the piston dynamic response. By coupling FDM for thehydrodynamic pressure field with the FEM for the piston deformation, wenumerically approximate the lubricantstructure interaction in an internalcombustion engine.
