Coming soon - Final product timing depends on legislative situation / 163 AVL M.O.V.E PN PEMS iS AVL PN PEMS iS with the GAS PEMS on top PORTABLE MEASUREMENT SYSTEM FOR PARTICLE NUMBER EMISSIONS APPLICATION The modular design enables a high flexibility for different applications: • Standalone PN PEMS configuration with single sample probe • Complete setup (Gas + PN PEMS) with combined sample probe BENEFITS AT A GLANCE • Compact, lightweight and robust solution optimized for RDE Innovative exhaust sample treatment to reduce particle losses and to improve the correlation with existing PN instruments • Modular concept: The PN PEMS iS can be operated both as a standalone device or integrated into the iS platform in combination with the Gas PEMS iS module The AVL M.O.V.E PN PEMS iS is a compact and robust continuous particle number #/cm³ measurement device for on-road application. This low weight and low power PN PEMS solution is especially designed to meet the Real Driving Emissions (RDE) requirements for LD vehicles. The modular concept enables the smart integration into the M.O.V.E iS platform and completes the AVL RDE solution for passenger cars. The PN PEMS iS incorporates AVL’s broad expertise in particle number measurement methodology. MEASUREMENT PRINCIPLE The sample probe is located at the tailpipe of the vehicle and has been optimized to keep particle losses as low as possible and achieve maximum reproducibility. The exhaust treatment unit includes a temperature controlled and diluted exhaust sampling unit and a volatile particle remover (VPR) to minimize particle losses and enables an optimum correlation to existing particle number (PN) instruments on the testbed compliant to UN-ECE R83. To fulfil the legislative requirements despite challenging limitations regarding size and weight, a highly efficient Catalytic Stripper was introduced for the first time to remove the volatile fraction of the engine exhaust. The compact and weight-optimized sensor is based on the Diffusion Charging (DC) principle and correlates size dependent with particle number #/ccm. This progressive sensor technology provides a continuous offset correction of the electrometer signal and enables the highest possible stability of the measured value.
