The implementation of such a limit in the European in-service conformity legislation is planned within the coming years. Soot and PM measurements are also important during development: Soot is an indicator of the combustion system quality and the efficiency of a filter system (DPF). PM is limited by legislation and needs to be checked already during development. Measurements on board a vehicle require compact, easyto 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 as well as additional signals which are 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. Correlation of PM PEMS with CVS
