Development of a Model for Piston Slap Noise Prediction in Reciprocating Internal Combustion Engines 973056

A model for piston slap force level prediction is being developed. The development project is scheduled to be carried out in three distinct steps, which are discussed here. Step one and part of two have already shown important features of the role of the oil film on the impact behavior. The Reynolds theory has been applied and a preliminary prediction model proposed. The piston-cylinder, wall-engine block structure is treated as 7 degree freedom system.
