This re��uires 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, ��oth in the US and in the EU. Soot and PM measurements are also important during development: Soot is an indicator of combustion system ��uality and the effi ciency of a fi lter system ����PF��. PM is limited ��y legislation and needs to ��e checked during development. Measurements on ��oard a vehicle re��uire compact, easy-to-install and robust devices which correlate to test cell equipment. MEASUREMENT PRINCIPLE The PM PEMS is a com��ination of two measurement principles and consists of two units�� the photo-acoustic measuring unit for the continuous measurement of soot concentrations and a gravimetric fi lter module which conditions the e��haust gas and measures PM using the gravimetric fi lter method. At the end of the test, the loaded PM fi lter is weighed with a micro��alance. By using the transient soot signal and the fi lter weight as inputs, a time resolved PM signal is calculated as re��uired ��y 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 e��haust �� ow meter, the PM PEMS, the AVL ��AS PEMS and additional signals re��uired 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.
