It is easy and intuitive to perform all functions in the standard operation of the CVS i60 SII. Remote operation concept and interactive self diagnosis functions to sensor and valve level allow for increased productivity as well as reduced and simplified maintenance and service work. APPLICATION The CVS i60 SII is used for the certification of all kinds of combustion engines and fully complies with the latest emission legislation for passenger cars and commercial vehicles, such as Euro 5/6 or EPA 40 CFR part 1065 and 1066. The CVS i60 SII supports all modern drive technologies like hybrid and gas engines as well as alternative fuels including hydrogen. The CVS i60 SII is available for flow rates up to 20m³ or 30m³ (LD), up to 60m³ (MD) or up to 90m³ or 160m³ (HD). BENEFITS AT A GLANCE • Simultaneous bag valve functionality, separated sampling lines or backflushable bag venturis for most accurate HEV/PHEV emission testing • Easy serviceability by front access for venturi calibration and pullout / 169 drawer for maintenance of pumps, MFCs, etc. • Particulate mass and particle number measurement of GDI and diesel vehicles via one dilution tunnel • Semi- or fully-automated LFE for venturi calibration • Automated CFO checks via iGEM CVS • Minimized total cost of ownership and less power consumption through frequency-controlled blower and alternative operation without heat exchanger EXHAUST GAS DILUTION SYSTEM AVL CVS i60 SII The CVS i60 SII is the most compact full flow dilution system on the market. With a total flow rate of up to 30 m³, all system components fit into one 19”-cabinet. The sophisticated gas flow system guarantees fast response times and the best reproducibility for gas analysis. The extended valve manifold with increased numbers of phases (max. five) and simultaneous analyzing, purging, evacuating and filling optimizes the running of test cycles, e.g. with regard to HEV/ PHEV applications. The modular design – with up to four main flow venturis, three bag sample venturis or, alternatively, with mass flow controllers – supports all possible applications on chassis dyno and engine testbeds. The patented angulated inlet tube allows particulate measurement in accordance with ECE, EPA and Japanese exhaust emission regulations with one dilution tunnel. MEASUREMENT PRINCIPLE The exhaust gas is diluted with filtered ambient air close to the tailpipe outlet and then homogeneously mixed in the dilution tunnel for particulate measurement. During each phase of a test cycle, the exhaust gas bags are filled proportionally to the main flow rate of the CVS. The integrated mass emissions are calculated using the background gas concentrations in the bag and the accumulated flow rate of the diluted exhaust.
