选择性催化还原（SCR）是将氮氧化物（NOx）转化为双原子氮和水以及少量二氧化碳的化学过程。通过添加汽车级尿素（称为柴油机尾气处理液（DEF）或商业品牌如AdBlue和Bluetech），将柴油引擎的有害NOx排放转化为无害的氮和水的一个过程。

SCR模块控制泵从储罐中抽出DEF，并用适当的计量阀将其注入柴油机废气中。为了优化燃油效率，在催化还原过程之后使用气体传感器，然后将气体传感器的信息输送到柴油引擎ECU，后者将该信息与引擎状态相结合，向SCR单元提供有关待释放的正确DEF液体量的准确信息。

我们为常用的无刷直流（BLDC）电机提供一系列三相栅极驱动器和功率MOSFET，以及SPC5 32位微控制器和带有调压器和CAN与LIN接口IC的专用电源管理IC，从而简化高效解决方案的设计过程。
