| 摘 要： | 在一台中速柴油机上进行了轻柴油和低质混合油的动力性能试验,通过对缸内压力曲线的分析,对比研究了轻柴油和低质混合油的缸内燃烧情况;比较了两种喷油嘴参数对应的柴油机动力性能;研究了燃油温度对低质混合油动力性能的影响。结果表明,采用原机喷油嘴,与燃用轻柴油相比,燃用低质混合油时,在中低负荷条件下,燃烧压升率变大,最高燃烧压力升高;高负荷条件下,缸内最高燃烧压力有所降低;采用喷孔数及喷孔直径均增加的新喷油嘴后,在各个工况下燃用低质混合油时的最高燃烧压力比燃用轻柴油时的高;随燃油温度升高,缸内燃烧压力升高,但燃油温度升高到一定限值后,动力性能下降。

| Abstract: | Dynamic performance tests were carried out on a medium speed diesel engine,using light diesel fuel and heavy fuel oil.Cylinder pressure was measured to evaluate the combustion characteristics.The engine's dynamic performance corresponding to the parameters of two different injection nozzle were compared.The influence of fuel temperature on the dynamic performance of heavy fuel oil was studied.Results show that : if the nozzle is kept unchanged,using of heavy fuel oil causes higher pressure increasing rate a... |
