配气相位对天然气发动机燃烧和排放的影响（Investigation of Effect of Cam Phase on Combustion and Exhaust Characteristics of CNG Engine）
天然气发动机 配气相位 燃烧 排放
2009/9/2
对改装为火花点火式天然气发动机的柴油机配气机构的配气相位进行了优化设计，并在发动机台架上进行了对比试验，研究了配气相位对发动机燃烧及排放的影响。试验结果表明：随着气门重叠角的减小，HC和NOx排放量有所降低，但高转速时过小的气门重叠角，不利于HC排放量的降低；气门重叠角的减小使得缸内可燃气体浓度降低，在抑制NOx生成的同时，也损失了部分功率，因而在降低有害排放的同时，还要兼顾动力性；随着转速的升高...

配流阀容积效率对三缸内燃水泵工作性能的影响（Effect of Distributing Valve’s Volumetric Efficiency on Working Performance of Three Cylinders Internal Combustion Water Pump）
内燃泵 配流阀 容积效率
2009/5/22
综合考虑液体可压缩性与液体连续流条件的影响，建立了三缸内燃泵(ICP)配流阀的动力学模型，研究了配流阀的容积效率特性。样机工作频率与配流阀的固有频率成整数倍关系时，容积效率大幅度降低。样机标定转速与容积效率最低时的转速较为接近，不利于系统正常稳定工作。容积效率的变化对ICP的燃油消耗率、输出流量、有效热效率、有效功率等性能指标影响较大，但对输出压力基本没有影响。
