·柴油機的另一種主要有害排放是氮氧化物。選擇性催化還原器（SCR）是通過在排氣中添加還原劑，在催化劑的作用下，將氮氧化物轉化為氮氣和水。

·可根據應用情況，選擇空氣助力或無空氣助力系統(tǒng)；
·空氣助力系統(tǒng)中的噴嘴設計簡單，應用可靠，耐高溫，不易結晶堵塞，通過自主設計的混合腔實現充分混合和霧化；
·無空氣助力系統(tǒng)無需壓縮空氣，系統(tǒng)結構簡單，更適用于中小型柴油車輛；
·自主設計生產的控制器，具備車載自檢功能（OBD）和發(fā)動機通訊；
·系統(tǒng)國產化率超過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%.
