我国相关部门正计划实施“中国非道路第四阶段排放标准”。据悉,颗粒和气氧化物(NOx)的限值已经定好,但实施的日期和若干技术细节还有待最终定案。该排放标准等效于美国4级过渡期和欧盟IIIB阶段排放标准。这些标准将对农用和工程机械行业,包括挖掘机、装载机、叉车和农用拖拉机等设备的生产商带来深远影响。对国四标准的实施Perkins早已经成功研制多个技术解
Relevant departments of our country are planning to implement “China’s non-road emission standards for the fourth stage.” It is reported that the particle and gas oxides (NOx) limits have been set, but the date of implementation and a number of technical details have yet to be finalized. The emission standard is equivalent to the United States 4 transitional period and the EU IIIB stage emission standards. These standards will have far-reaching implications for the agricultural and construction machinery industries, including manufacturers of excavators, loaders, forklifts and agricultural tractors.
