摘要：
The purpose of this study is to analyze the effects of combustion on diesel spray included angle, nozzle hole number, and compression ratio. In order to investigate effects of each factor, the other factors except the comparison factor were kept constant under the same conditions. The results of the study were that as nozzle hole number increased, CO and Soot emissions and indicated specific fuel consumption were increased. In addition, the increase of included spray angle caused the spray could not evenly spread out to combustion chamber, CO and Soot emissions became increased. Finally, indicated specific fuel consumption was decreased that is because of compression ratio was increased.
