Summary:

The subject of this paper is the discussion of a non-dimensional combustion model that relies on the concept of mixing controlled combustion (MCC Heat Release Rate) avoiding the detailed description of the individual mixture formation and fuel oxidation processes.For diffusion combustion in today's direct injection diesel engines it can be shown that the rate of heat release (ROHR) is controlled mainly by two items, id est the instantaneous fuel mass present in the cylinder charge and the local density of turbulent kinetic energy.Both items can be derived from the injection process, the instantaneous fuel mass being the difference of fuel injected minus fuel burnt and the turbulent kinetic energy being produced mainly by the momentum of the fuel sprays. Following this strategy, the injection process is now understood as the most important controlling factor for the heat release rate
