摘要
本文介绍了直喷式2135型柴油机和涡流室式S195型柴油机在各种工况下燃用柴油、柴油掺水和添加燃油催化剂时的燃烧循环波动率,并对此进行了实测。试验中选用了最高爆发压力p_(max)、平均指示压力p_i 及最高燃烧温度T_(max)三个参数表征循环波动率。计算了这些参数的标准差,应用了它们的偏差概率分布直方图。文中详细分析了各参数的影响程度和变化规律,提供了变化的具体数值,从而得出一些明确的结论。
This paper introduces the cycle-to-cycle variation study under variousoperating conditions on direct injection type diesel engine 2135 and swirlcombustion chamber type engine S195 using pure diesel fuel.water emulsionand additives.The cycle-to-cycle variation is expressed by three parameters p_(max)、p_i and T_(max) in these experiments.And the standard deviations of theseparameters are evaluated,the histogram of probability distribution of theirdeviation is applied.In this paper,the degree of influences and the law ofvariations of every parameter are analyzed in detail,some specific data ofvariations are offered;thereby explicit conclusions are obtained.
