选择性催化还原器（SCR）
·柴油机的另一种主要有害排放是氮氧化物。选择性催化还原器（SCR）是通过在排气中添加还原剂，在催化剂的作用下，将氮氧化物转化为氮气和水。
·可根据应用情况，选择空气助力或无空气助力系统；
·空气助力系统中的喷嘴设计简单，应用可靠，耐高温，不易结晶堵塞，通过自主设计的混合腔实现充分混合和雾化；
·无空气助力系统无需压缩空气，系统结构简单，更适用于中小型柴油车辆；
·自主设计生产的控制器，具备车载自检功能（OBD）和发动机通讯；
·系统国产化率超过90%。
·NOx is one of the major pollutants of diesel exhaust. Selective Catalyst Reduction (SCR) is a system that converts NOx to N2 and H2O by adding reducing agent into exhaust assisted by catalyst.
·Can supply both air-assisted and airless system;
·Air-assisted system adopts nozzle that is simple structured, reliable, high temperature resistant, and urea crystallization resistant. Achieving fine mixing and atomization through self-designed mixing chamber;
·Airless system doesn’t need compressed air, the system is simpler, more suitable for medium and small vehicle applications;
·Self-designed controller has OBD and engine communication capabilities;
·Localization rate of the system >90%.
