Detection of Ammonia Slip Using NOx Sensor Signal Processing

The current production NOx sensor is cross-sensitive to NH3. Therefore, it provides noisy feedback to the control algorithm. Presented are some signal processing observations which can help to provide insight to the true nature of the exhaust downstream the catalyst. However, there is some inherent noise to these methods. As future emission regulation become more stringent, the accuracy of the ...

NH3 Filling Level Control for SCR Catalysts on the Basis ...

2017-01-19· Based on a physical model of SCR, IAV has developed a software to compute the quantity of AdBlue dosed in SCR systems. The low-dimensional SCR model is computed on the control unit and can be continuously checked against the information measured by the downstream NO x sensor using an extended Kalman filter. This results in a closed-loop control of the NH 3 filling level in the SCR …

SCR Technology to Meet Future Diesel Emission Regulations ...

introduced in combination with the use of AdBlue (a % urea solution in water meeting the DIN 70070 standard), as reagent. This reagent is needed to reduce the oxides of nitrogen (NOx) into nitrogen (N 2), a natural component of the air we breath. The SCR technology will be phased-in gradually as from 2005 until 2006. This move by the heavy-duty commercial vehicle industry has been taken to ...
