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
柴油機缸內的火焰輻射受諸多因素的影響，用理論分析法來確定它是相當困難的，由於柴油機缸內火焰輻射特性依賴于缸內的燃燒過程，而燃燒過程中的實際熱力狀態又可用示功圖來分析，因此藉助於火焰輻射與缸內熱力參數之間的這種間接關系，建立了一種計算柴油機缸內火焰輻射傳熱的新模型，利用該模型對一臺直噴柴油機缸內火焰輻射熱流量隨曲軸轉角的變化情況進行了計算，將計算結果與實測結果進行了比較，表明該模型能較好預測缸內火焰輻射傳熱量。 -
