/ 189 DEVICE FOR MEASURING THE EXHAUST MASS FLOW RATE OF INTERNAL COMBUSTION ENGINES AVL M.O.V.E EXHAUST FLOW METER (EFM) The AVL M.O.V.E EFM is a cost effective, accurate and ro��ust e��haust mass �� ow measuring device with a special focus on the In-Use/ Real ��riving Emissions ��R��E�� testing applications. The AVL EFM is fully integrated into the comprehensive AVL M.O.V.E in-vehicle measurement systems and can also ��e used as a ��standalone device�� e. g. on chassis dynos or engine test cells. Different interfaces allow for a �� e��i��le integration into automation and data ac��uisition systems. MEASUREMENT PRINCIPLE The AVL M.O.V.E EFM is ��ased on the proven and ro��ust ��differential pressure�� measurement principle. It consists of the EFM tu��e which is installed on the tail-pipe of the vehicle and the EFM control box which includes the electronics and the pressure transducers. The EFM tu��e and the EFM control ��o�� is separated for the most �� e��i��le installation. The EFM ��o�� is temperature conditioned to achieve high accuracy at changing ambient conditions. The usage of high-speed pressure transducers ensure accurate measurements at dynamic �� ow conditions in the e��haust duct. The EFM Control Bo�� is water and dust protected ��IP Protection Class 65�� for the most relia��le operation under harsh am��ient conditions. APPLICATION Due to its robust design, high measurement accuracy and �� e��i��ility in installation and operation, the AVL M.O.V. E EFM is a perfect solution for the In-Use/ R��E testing application or use on engine test cell or chassis dyno. It can be �� e��i��ly used either in com��ination with AVL M.O.V.E or as a standalone device. BENEFITS AT A GLANCE �� Wide range of supported applications�� From small passenger car up to heavy- duty truck engine, operation either in combination with AVL M.O.V.E or standalone e. g. on test cell AVL M.O.V.E EFM Control Box with EFM Tube and Extensions Benchmark result for a 4-cylinder diesel engine • High measurement accuracy even at changing ambient and highly dynamic conditions in the exhaust �� Fulfi lls all relevant legal requirements �� Fle��i��ility in installation to allow for the most easy and safe mounting �� ��uick and easy integration into AVL M.O.V.E and other automation and data ac��uisition systems
