欧盟要求陆地机械(包括工程机械和户外动力设备)使用的柴油机和汽油机,于2019年开始分阶段执行STAGE V排放标准。欧盟排放标准的更新点,在于加入了针对多种非公路车辆对颗粒物数量(PN)的限制。为帮助原始设备制造商满足新标准,John Deere动力系统已经发布了其满足StageV排放标准的系列发动机。利用全新催化剂技术、排放控制校准和下一代后处理解决方案,John Deere PowerT ech系列发动机较以
The EU requires that diesel engines and gasoline engines used on land machinery (including construction machinery and outdoor power equipment) begin implementing STAGE V emission standards in phases by 2019. A more recent update to the EU’s emissions standards is the addition of restrictions on the number of particulate matter (PN) for many off-highway vehicles. To help original equipment manufacturers meet new standards, John Deere Powertrain has released a series of engines that meet StageV emission standards. With new catalyst technology, emission-control calibration, and next-generation aftertreatment solutions, the John Deere PowerTech family of engines
