The intake generated mean motion is generally augmented by the piston bowl configurations to result into desired level of fuel-air mixing in an engine combustion chamber. The swirl and squish are the two in-cylinder air motions identified in direct injection diesel engine combustion chambers. In this paper, an attempt is made to model swirl and squish interactions through a phenomenological approach considering the temporal variations of wall friction and moment of inertia of the fluids inside the piston bowl and the annular space. The model predictions are found to be in good agreement with the available experimental data.
