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™ contriutes to effi - cient SCR system testing in all development stages of SCR system application and verifi cation. MEASUREMENT PRINCIPLE Etremely small ow uantities and high levels of ow dynamics reuire a measurement position in the direct vicinity of the injector to minimize temperatures in uence on the results. Roustness 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, eile use and comfortale stand-alone functionality
