More than 45 years of concentrated know-how in the field of fuel consumption measurement technology, technological diversity and clever modular product concepts, in combination with a global presence and sophisticated service and system competence, make AVL the clear leader in the field of consumption measurement technology the world over. BENEFITS AT A GLANCE • Shorter time to achieve development objectives due to reliable AVL fuel consumption measurement systems, ensuring high levels of engine testbed availablity and significantly reduced test effort thanks to shorter measurement times and high levels of measurement accuracy, one example being the reduction of the measurement effort during automatic engine calibration • Protection of investments through modular design, subsequent expandability and adaptation to new injection systems and applications • Supporting bio fuel such as bio diesel and bio ethanol • Increased productivity of the engine test facility due to lower product lifecycle costs: simple and projectable maintenance and service as well as quick availability of spare parts via AVL eSpares™ TASK Stricter laws and regulations with regard to CO2 and fuel consumption reductions increase the pressure to develop engines even faster, coupled with rapidly increasing measurement expenditures. Engineers developing diesel and gasoline engines are increasingly forced to implement measurements in automatic operation with ever shorter measurement times or in transient modes. In addition to accelerated test procedures, new combustion and injection technologies require instrumentation devices delivering precise measurements even for efficient engines with low consumption levels during cyclic tests under partial load. And this is all the more true if fuel is a target variable in automated optimization and calibration procedures. The call for higher testbed efficiency does not only mean an easy installation and quick commissioning procedure for the measurement system; it also means a reliable fuel supply for the engine with preselected parameters, such as fuel temperature and pressure. Precision fuel temperature control is required to achieve high- measurement accuracy in the overall system on the engine testbed, even in case of low fuel consumption values. The layout of the fuel consumption measurement system, for example having fuel lines which adapt to different mixture preparation systems, has a decisive influence on the quality of the measurement results. Engines for alternative fuels also require the compatibility with bio diesel or alcohol admixtures of up to 100%. / 126
