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。
