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 specific 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 flow 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™ contributes to efficient SCR system testing in all development stages of SCR system application and verification. MEASUREMENT PRINCIPLE Extremely small flow quantities and high levels of flow dynamics require a measurement position in the direct vicinity of the injector to minimize temperature’s influence on the results. Robustness 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 • Efficient urea dosing strategy development due to dynamic correlation • Optimized system solution for SCR-specific operational conditions • Immediate detection of dosing deviations or SCR system malfunction and exact identification of corresponding operational conditions • Fast testbed integration, flexible use and comfortable stand-alone functionality
