| Abstract: | For the urging stage Ⅳ emission requirement and the costly SCR abroad,a low cost gauging device for urea SCR system was designed.The actuators of the device were provided by domestic manufactures.The controller used the Freescale 9S12 single chip processor and its driving program was developed with Codewarror matched compiling tool.The flow calibration of solenoid valve with the device laid a foundation for the upper control strategy determination. |
