    摘要：在同一台直喷式增压柴油发动机上分别进行了0#柴油和葵花籽油的性能和排放试验。通过实验结果分析,发现葵花籽油的滞燃期比0#柴油长,有效燃油消耗率高于0#柴油,但是在高速高负荷工况下除了NOx排放略高于0#柴油,其HC、CO排放及烟度值明显优于0#柴油。

    Abstract: The combustion performance and emissions of petroleum diesel and sunflower oil were compared in this study.The tests were performed at steady state conditions in a four-cylider turbocharged DI diesel engine.The experimental results showed that that sunflower oil provided a longer ignition delay period than petroleum diesel along with the increase specific fuel consumption,but under the high speed and high load work condition,the sunflower oil show a better CO,HC and smoke intensity emissions performance except for a slightly increased NOx.
