【摘要】 本文运用计算机对等压卸载出油阀的参数进行了分析,优选出一组较佳参数的等压卸载出油阀,并装入16240Z柴油机燃油喷射系统进行了实验。结果表明,等压卸载燃油喷射系统不仅在高工况时具有良好的卸载性能,而且在部分工况(尤其在低工况)下也有较高的残余压力。更多还原

【Abstract】 The parameters of a constant pressure unloading delivery valve are analysed by a digital computer.An optimized constant pressure unloading delivery valve for high-supercharged medium-high speed diesel engines has been designed and tested on the injection system of the 16240Z Diesel Engine.The results of the experiments show that in high operating conditions the constant pressure unloading delivery valve not only satisfies the unloading performances but also has the higher excessive pressure in low operating conditions.更多还原
