This requires manufacturers to prove their vehicles meet the PM limits even after many years of operation. A corresponding European In-Service Conformity legislation is already in preparation as well as regulations for off-road machinery, both in the US and in the EU. Soot and PM measurements are also important during development: Soot is an indicator of combustion system quality and the efficiency of a filter system (DPF). PM is limited by legislation and needs to be checked during development. Measurements on board a vehicle require compact, easy-to-install and robust devices which correlate to test cell equipment. MEASUREMENT PRINCIPLE The PM PEMS is a combination of two measurement principles and consists of two units: the photo-acoustic measuring unit for the continuous measurement of soot concentrations and a gravimetric filter module which conditions the exhaust gas and measures PM using the gravimetric filter method. At the end of the test, the loaded PM filter is weighed with a microbalance. By using the transient soot signal and the filter weight as inputs, a time resolved PM signal is calculated as required by the in-use legislation. The calculations are available in AVL CONCERTO PEMS. APPLICATION The AVL PM PEMS is fully integrated into the AVL M.O.V.E in-vehicle testing platform. AVL System Control is the central device that integrates the exhaust flow meter, the PM PEMS, the AVL GAS PEMS and additional signals required for mass emission calculations. The PM PEMS can also be easily integrated into existing portable systems. In this case, the device can be operated independently as it does not need any external input signals. Control, data storage and operation are performed via notebook. The data integration is done with AVL CONCERTO PEMS. BENEFITS AT A GLANCE • Ready for Euro VI HD in-service conformity (ISC) testing due to proportional sampling • US EPA approval for Heavy- Duty in-use testing (HDIUT) • Short installation time and easy to operate • High measurement accuracy • Easy integration into existing PEMS systems • Robustness proven in multiple evaluation projects and with customers • Based on proven AVL measurement technology Correlation of PM PEMS with CVS
