摘　　要：随着化石能源日渐枯竭和内燃机排气污染环境的问题不断加剧,内燃机代用燃料的高效利用成为了汽车行业的新研究热点之一。我们在不改变柴油机结构参数的基础上,研究了桐油在柴油机中的排放特性。实验结果表明,桐油占小比例的桐油—柴油混合燃料、桐油占大比例的正丁醇-乙醇-桐油混合燃料以及纯桐油燃料都能够有效地降低柴油机的烟度和NOx排放物。As the problems of fossil fuels depletion and the environmental problem caused by the internal combustion engine exhaust are getting worse and worse, how to make most use of alternative fuels in a intermal combustion engine has become one of the new hot topics in the automotive industry. In this paper, the diesel engine burns tung oil on the condition that its structure parameters are not changed, emission characteristics of the diesel engine are explored. The experimental results show that tung oil-diesel blended fuel with small proportion tung oil, butanol-ethanol- tung oil blended fuel with large proportion tung oil and pure tung oil fuel can reduce smoke and NOx emissions of diesel engine efficiently.
