COUNT ON IT The APCplus – AVL Particle Counter measures the transient particle num��er concentration of solid particles in com��ustion engine e��haust. The new core sensor AVL CPC of enhanced functionality further improves the APCplus performance ��y ��oth optimizing service and cali��ration costs. It complies with the legal re- ��uirements of UN-ECE R83 and R49 and is the ideal tool for specifi c R���� applications to ��e ahead of the RDE challenge. / 176 SIMULATION SOLUTIONS TEST SYSTEM SOLUTIONS TESTING EQUIPMENT Dynamometers and Actuators Vehicle Testbeds Test Cell Mechanics and Control Rooms Media Conditioning Consumption Measurement Injection Testing Combustion Measurement Emission Analysis and Measurement In Vehicle Measurement SIMULATION TOOLS TESTING TOOLS CUSTOMER SERVICES BENEFITS AT A GLANCE The ��rand-new com��ination of APCplus with ��uilt-in AVL CPC allows�� �� Highest application �� e��i��ility due to a three times higher sensor concentration range and best in class dilution accuracy and stability • Maximum test utilization even under harshest testbed conditions due to a 60 �� higher temperature operating range of the AVL CPC �� Uni��ue com��ination of APCplus and AVL Smart Sampler for highest data quality combined with minimum test effort �� Reduction of service and cali��ration costs ��y up to 20 �� and throughput times ��y up to 25 �� �� AVL ActiveLink™ for a more effi cient and �� e��i��le use of AVL measurement instruments, especially in com��ination with AVL PUMA ��he fi gure shows the results from an NEDC test on two different vehicles. The number of particles for vehicle A has signifi cant peaks in comparison to vehicle B. Despite concentrations being very low, the differences in emissions can be measured with the AVL Particle Counter. APCplus – now AVL CPC inside MEASUREMENT PRINCIPLE The exhaust sampling is carried out, conducted either directly at a CVS tunnel or a partial �� ow dilution system ��PF��S��, or, for R���� applications, directly at the tailpipe of an engine testbed with a heated sample line. Legislation ��UN-ECE R83 and R49�� re��uires a comple�� conditioning system for removing the volatile fraction of engine exhaust. It consists of: �� a hot primary dilution ��PN��1��, �� an evaporation tu��e ��ET�� and �� a cold secondary dilution ��PN��2��. AVL has developed a patented chopper diluter to ensure a very high, size-independent dilution that also allows to use the system to sample from raw exhaust gas during R&D. The particle number concentration is measured ��y a particle counter ��CPC�� with a cut-off characteristic specially adapted for automotive applications. The e��tended measurement and operating temperature range of the AVL CPC guarantees a maximum of test results even under toughest conditions on the engine testbed. APPLICATION �� Certifi cation according to UN-ECE R83 and UN-ECE R49 procedure • Applications in research and development • Applicable on engine and chassis dynos �� Sampling from CVS systems, partial �� ow dilution tunnels or directly from raw exhaust • Suitable for diesel and gasoline engines Open 2™ testbed automation systems 600 800 1000 Time s Engine A Engine B 1200 500 700 900 1100 Opacity Tailpipe Online Particle Number Online Vehicle Speed 100 200 300 400
