本文通过对液力传动式推土机所配柴油机进行的高原台架试验,分析研究了液力传动式推土机的高原动力特性,提出了一种解决高原地区工程机械动力性能下降的方法,并通过PD165YG推土机在4200m高海拔地区的实地试验,验证了改进后的设计方案。
Based on the plateau test of the diesel engine equipped with hydraulic transmission bulldozer, this paper analyzed the plateau dynamic characteristics of the hydraulic transmission bulldozer and proposed a method to reduce the dynamic performance of construction machinery in the plateau. The method of PD165YG bulldozer The field test at 4200m high altitude verified the improved design.
