Fuel economy, CO2 emissions and RDE legislation are forcing OEMs to make engines more efficient. Thereby, they have to deal with rising costs and shorter development times. RDE in particular is responsible for a considerable increase in the time and effort required for calibration and measurement. This is driving the use of simulation in the engine development process and thus increasing the demand for high quality measurement data. This requires the highest availability of test equipment at affordable costs.
The AVL FuelExact ensures best-in-class data quality due to highest possible accuracy in temperature control and the application-oriented design of the measuring system.
AVL FuelExact can be used with different injection systems and is not influenced by pressure surges within them. Highly efficient, it is designed with the user in mind. It has a large number of diagnostic functions and easily accessible components that make servicing fast and simple.
Standard interfaces and diagnostic functions allow for easy set up and operation. Additionally, calibration to ISO, UNECE R49 and US EPA Part 1065 via AVL Fuel Reference ensures it is globally compliant.
A fuel circulation rate of up to 840 l/h (or 2400 l/h with an external heat exchanger) results in high performance and robust results.

Best-in-Class Data Quality
Best-in-class data quality thanks to extremely high temperature control accuracy and application-oriented design of the measuring system.
Cost Saving
Protection of investment due to the higher engine feed pressure of 10 bar and higher measurement range of 500 kg/h. The device can also handle high engine return flow rates.
Easy Use And Flexibility
Fast and easy setup on the test bed by means of optimized design and flexible adaption to different state-of-the-art fuel injection systems.
Modular Setup
The modular setup makes it possible to adapt to different fuel injection systems at any time through the utilization of suitable pressure control modules.
Investment Protection
The FlexFuel version of AVL FuelExact Mass Flow is suitable for commercial gasoline and diesel fuels as well as for alcohol admixtures of 100% methanol or ethanol and up to 100% biodiesel.
User-Friendly Interface
The user-friendly, standardized, AVL interface technology RSI (Remote Service Interface) is used to significantly reduce training and installation expense. Simple integration via Ethernet into the testbed automation system, test bed network or a laptop is possible via the utilization of WEB technology.
