AB During past two decades, combustion of the Homogeneous Charge Compression Ignition (HCCI) type has shown itself as a well-known and applicable method for several types of internal combustion engines, whether stationary or mobile. This work is intended to develop a mathematical model in order to analyze radiation heat transfer in HCCI engines. In the current study, in order to consider in-cylinder charge heterogeneity, multizone modeling is adopted. Then, suitable equations of emissivity and absorption coefficients of the in-cylinder gaseous species are used, and applied to the equations of radiation heat transfer between the zones, and eventually are converted to the FORTRAN code. The in-house code is applied to a detailed code of HCCI combustion and its results are obtained from three different cases of engine operating conditions. For validating the numerical results, experimentally measured pressure data is used showing very good agreement. Moreover, results obtained by using the model which took into account radiation are compared with results of no-radiation model.
