经济的发展使环境面临日益严峻的污染问题,人们对环境保护的重视程度也越来高。当前,非道路移动机械国三排放标准已在全国实施,而国四排放标准的建议实施日期为2019年,因此,提早研发应用、增强技术储备、加深技术了解、摸底配套资源,以及不断提升排放标准成为工程机械行业面临的重要课题。在BICES 2017展会上,众多参展企业展示了其满足国四标准的发动机产品与技术。其中,Perkins所展示的各类先进技术
Economic development makes the environment face increasingly serious pollution problems, and people attach more importance to environmental protection. At present, the national emission standards for non-road mobile machinery have already been implemented throughout the country. The implementation date of the fourth emission standard is 2019. Therefore, early application of R & D, enhancement of technical reserves, deepening of technological understanding, matching of supporting resources and continuous improvement of emission Standard construction machinery industry is facing an important issue. At BICES 2017, many exhibitors demonstrated their engine products and technologies that meet the requirements of the National IV standard. Among them, Perkins demonstrated various advanced technologies
