Compliance with the challengingly low limits of future exhaust emission legislation requires maximum NOx conversion ratios while avoiding ammonia slip. Successful urea dosing strategy development for a specifi c engine/SCR system/catalyst combination includes accurate dosing calibration over the entire engine map and comprehensive emission cycle testing. Enabling AVL measurement technology allows fast setup, easy handling, robustness and durability in addition to accurate and reliable measurement data. APPLICATION AVL PLUrea™ provides stationary urea �� ow metering as well as highly dynamic consumption measurement during transient test cycles. The system solution is used on engine or chassis dynamo testbeds as well as in vehicle testing. With accurate online measurement, AVL PLUrea™ contri��utes to effi - cient SCR system testing in all development stages of SCR system application and verifi cation. MEASUREMENT PRINCIPLE E��tremely small �� ow ��uantities and high levels of �� ow dynamics re��uire a measurement position in the direct vicinity of the injector to minimize temperature��s in�� uence on the results. Ro��ustness to pressure pulsations resulting from the injection is, of course, an important precondition in this position. With their dual measurement principle PLU sensors are ideally suited to these measurement conditions. BENEFITS AT A GLANCE �� Effi cient urea dosing strategy development due to dynamic correlation • Optimized system solution for SCR-specifi c operational conditions • Immediate detection of dosing deviations or SCR system malfunction and exact identifi cation of corresponding operational conditions • Fast testbed integration, �� e��i��le use and comforta��le stand-alone functionality
