  4. It is very difficult to analyze flame radiation in the cylinder of a diesel engine by theoretical method since flame radiation is a function of many parameters, such as the combustion process, the geometrical description of the chamber, the soot formation and oxidation processes, the soot radiant temperature and soot absorption coefficient. the radiant property of the flame in a cylinder is dependent on the combustion process. but the thermodynamic state of real engine cycles can be analyzed from the pressure - volume diagrams in the cylinder. thus a new thermodynamic computational model is set up for the flame radiation in the cylinder of a diesel engine based on the indirect relationship between the flame radiation and the pressure - volume diagram of the combustion process in this paper. the flame radiant heat flux in the cylinder of a di diesel engine is calculated with the variation of crank angle by this model. compared with measured values, the result of the computational values shows the model is available to represent the effects of flame radiation
