MEASUREMENT PRINCIPLE The FuelExact™ exists in two versions: one based on the PLU measuring principle and one based on the Coriolis measuring principle. For further information, please refer to page 108. APPLICATION AVL FuelExact™ covers applications from single-cylinder up to 2,500 kW engines in the field of engine research and development. Due to the high data rate of 20Hz and the fast step response, the system is ideally suited for transient calibration methods that are increasingly applied in the field of engine development. The FlexFuel version expands the application range towards development tasks in the field of bio fuels. New and improved features consistently safeguard your investment. BENEFITS AT A GLANCE • High flexibility for adaptation to different injection systems as well as a wide range of engine powers up to 2,500 kW • High efficiency on the testbed by unique repeatability and reproducibility of measurement values at minimum measurement time • Easy service due to a large number of diagnostics functions as well as easily accessible hardware components • Minimized commissioning effort via standardized inter faces and diagnosis functions • System calibration according to ISO, UN ECE R49 & US EPA 40 C.F.R. Part 1065 via AVL Fuel Reference • Measurements are not influenced by fuel pressure pulsations generated by the engine fuel injection system FUEL CONSUMPTION MEASUREMENT 1 Inlet 2 Gear meter 3 Piston sensor 4 Piston 5 Bypass 6 Outlet 7 Servo motor 8 Encoder 9 Controller 10 Signal output
