選擇性催化還原器(SCR)
·柴油機(jī)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(zhuǎn)化為氮?dú)夂退?/font>
·可根據(jù)應(yīng)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(shè)計(jì)簡單,應(yīng)用可靠,耐高溫,不易結(jié)晶堵塞,通過自主設(shè)計(jì)的混合腔實(shí)現(xiàn)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(jié)構(gòu)簡單,更適用于中小型柴油車輛;
·自主設(shè)計(jì)生產(chǎn)的控制器,具備車載自檢功能(OBD)和發(fā)動(dòng)機(jī)通訊;
·系統(tǒng)國產(chǎn)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%.
