| Abstract: | A theoretical calculating method has been developed for calculating diesel droplet evaporation and combustion process. The two Stages of the evaporation, non-steady evaporation and steady evaporation have been taken into account. An algebraic equation has been proposed for solving the instantaneous variation of droplet diameter during the evaporation. An example calculation has been carried out for a direct-injection diesel engine. The calculated instantaneous heat-releasing rate and cylinder pressure accord well with the experimental results. |
