产品亮点:新型节油发动机、简化维护、改良操作台本届BICES展会,全球工程机械龙头企业Caterpillar(卡特彼勒)的展台独具一格,展出的多款产品吸引了大量的参观者,其中,2013年9月10日正式发布的Cat 320D系列2型挖掘机尤为引人注目。该液压挖掘机是基于Cat320D的稳健表现开发出来的,采用了C7.1型发动机,并使用电动调速器来控制其机械驱动低压燃油喷射系统。在燃油质量略差的地区,这种新系统能够确保机器的最佳性能和可靠运转。在不同的工作模式下,新型发动机的油耗与之前机型相比降低约3%~5%。在
Product Highlights: New Fuel-Efficient Engine, Simplified Maintenance, Improved Operator Station At this year’s BICES exhibition, the world’s leading construction machinery company, Caterpillar, has a unique booth featuring a variety of products on display, attracting a large number of visitors, Among them, the Cat 320D Series 2 Excavator, which was officially released on September 10, 2013, is particularly noticeable. Developed based on the robust performance of the Cat320D, this hydraulic excavator uses a C7.1 engine and uses an electric governor to control its mechanically actuated low pressure fuel injection system. With slightly less fuel quality, this new system ensures the best performance and reliable operation of the machine. In different operating modes, the fuel consumption of the new engine is reduced by about 3% to 5% compared with the previous models. in
