test results and second proposal by Japan NO2 Measurement Method test results and second proposal by Japan 9 December 2011
NO -> NO2 reaction ratio NO2 reaction ratio is less than 2% when NO concentration in bags is less than 4 ppm (=equivalent Euro 5 or 6 level) 3 Test results (measured by CLD) ● 2.5 *: average concentration @ CVS 12m3/min 2 Theoretical line of NO->NO2 reaction ratio D-Euro6* NO -> NO2 reaction ratio in Bag after 15 min. (%) G-Euro5,6* 1.5 1 D-Euro5* 0.5 1 2 3 4 5 6 Bag-NO Concentration (ppm) Remind:WLTP-DTP-AP-04-21 japanese proposal NO2 (9/10 DEC. 2010)
NONO2 reaction ratio is less than 3% in 30 minutes, almost same results as in 15 minutes
【Results】 NO2 reaction ratio was found to be very small, less than 3%, in sampling bags at the NOx level which comply with EURO6 【Japan Proposal】 Japan requests to adopt NO2 Measurement Method using bags as well as NO integration method
