The latest requirements of global emissions regulations are complied with by the new iGeneration Series II product line. AVL is able to offer products with the highest quality available on the market. Testbed solutions with permanent automation and data analysis integrated in the best possible manner provide the basis for the highest possible productivity. AVL particulate measurement technology comprises a wide range of applications. AVL offers test devices for measuring the lowest soot concentrations, for gravimetric measurements and for particle number counting as well as portable devices for in-vehicle testing during R&D and in-use compliance testing. Special conditioning units allow for measurements at high temperatures and pressures in front of filter systems (DPF). These special conditioning units also enable test cycles during high altitude simulations. TASK The dramatically decreasing emission limits and the increased use of alternative fuels pose significant challenges for engine and vehicle developers. Due to more complex engine and exhaust gas aftertreatment strategies and new requirements, such as the limitation of the particle number and the concentration of NH3, the complexity of testbeds and the requirements for automation systems are dramatically increasing. Along with the currently limited emission components, more and more substances need to be measured. These include, for example, nitrogen compounds such as NO, NO2, NH3, N2O, HNCO and aldehydes such as formaldehyde and acetaldehyde. Further requirements result from the “In-Use” and “Real Driving Emissions” legislation, which requires checking vehicles in real operation with portable emission measurement systems. The requirements for sampling are increasing as well, for example due to higher emission pressures on filter systems and because of the need to avoid chemical reactions and deposits during gas sampling in emission measurements of SCR systems. The requirements placed on operators and for the automation systems are increasing because of the rising number of measurement parameters and device subsystems needed. At the same time, the demand for an increase in productivity has to be met. AVL has optimized its emission measurement technology for these challenges and offers futureproof system solutions combined with an integrated testbed automation system.
