APPLICATION The CVS i60 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 upcoming 1066. The CVS i60 supports all modern drive technologies like hybrid and gas engines as well as alternative fuels including hydrogen. The CVS i60 is available for flow rates from one to 30 m³ (LD), eight to 60 m³ (MD) or from 15 to 160 m³ (HD). BENEFITS AT A GLANCE • Best accuracy and reproducibility for ultra-low emission sampling in compliance with the latest legislation • Most compact design, reduced test cell floor space • Simultaneous analyzing, purging, evacuating and filling of the bags (max. 20) • Particulate measurement of GDI and diesel vehicles via one dilution tunnel • Automated CFO checks and LFE calibration via iGEM CVS • Minimized total cost of ownership through frequency-controlled blower and alternative operation without heat exchanger / 147 It is easy and intuitive to perform all functions in the standard opperation of the CVS i60. 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. 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 JASIC legislations 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. VTi273 dilution tunnel for single tunnel arrangement with angulated inlet tube for switching between diesel and gasoline applications.
