336D2 XE是在336D2的基础上应用了液压混合动力技术的版本,由于吨位与336E H或336F XE属于同一级别,因此采用的混合动力系统各部件应该是相同的,所达到的节油效果也是相近的。日前,卡特彼勒在中国推出了336D2 XE挖掘机,至此,卡特彼勒为中国用户同时提供了336D、336D2、336D2 GC和336D2 XE四种同级别产品。而在美国,卡特彼勒则新发布了336F XE。那么新的“XE”到底是什么呢?要想弄明白“XE”的来龙去脉,得从卡特彼勒的“H”说起。众所周知,2012年10月,卡特彼勒在美国发布了首款液压混合动力的挖掘机336E H,经过一段时间的用户试用后,
336D2 XE is based on the 336D2 hydraulic hybrid technology version, the tonnage and 336E H or 336F XE belong to the same level, so the components used in hybrid systems should be the same, the fuel economy achieved similar results of. Recently, Caterpillar launched the 336D2 XE excavator in China. At this point, Caterpillar has delivered 336D, 336D2, 336D2 GC and 336D2 XE for its Chinese users at the same time. In the United States, Caterpillar released the new 336F XE. So what is the new “XE” in the end? To understand the ins and outs of “XE”, let’s start with Caterpillar’s “H”. As we all know, in October 2012, Caterpillar released in the United States the first hydraulic hybrid excavator 336E H, after a period of user trial,
