In this study, the effect of injection pressure, vessel pressure, and vessel temperature on the spray cone angle and the flame angle was investigated by using constant volume combustion vessel in order to develop calculation model of spray combustion for marine diesel engines. As a result, an experimental formula was obtained as a function of injection pressure and vessel temperature related with the spray cone angle. The other formula was obtained as a function of vessel pressure and vessel temperature related with the flame angle. From the comparison between the simulation and the experimental result of the flame position, it was found that a blue flame front can be estimated by the calculation of simple flame propagation.
