Summary:

A new model that includes the effects of spatial non-uniformity for the heat release analysis of internal combustion engine data has been formulated. The model has a form similar to the simple single zone thermodynamic models if two effective values of the ratio of specific heats T are defined. These values, denoted by γV and γH in the model, are weighted spatial average values of Y, and are dependent on the structure of the flame. These values have been evaluated using a three-dimensional numerical simulation of diesel combustion. Then the model is applied to the heat release analysis of diesel combustion data from a Rapid Compression Machine. The results show that the calculated cumulative net heat release is significantly higher (17% in this case) than that calculated using a single zone model
