Field Test Trucks Fulfilling EPA'07 Emission Levels On-Road by Utilizing the Combined DPF and Urea-SCR System 2006-01-0421
Two campaigns measuring on-road emissions of 23 VN-trucks on a randomly chosen driving cycle, consisting of 10 miles two-lane and 8 miles four-lane road were performed. The first, during October 2004, showed tailpipe NOx emissions on fleet average of 1.06 g/bhp-hr including the time the exhaust gas temperature was below 200°C. The second, during June 2005, showed tailpipe NOx emissions on fleet average of 1.13 g/bhp-hr including the time the exhaust gas temperature was below 200°C. Complementary measurements in a SET-cycle (13 point OICA-cycle) on a chassis dynamometer showed a tailpipe emission of 0.008 g PM per bhp-hr. Moreover, cost analysis show that the diesel fuel consumption remains unchanged whether the truck running on ULSD is equipped with a Combined Exhaust gas AfterTreatment System (CEATS) installed or not.
