| Abstract: | Based on the WLTC test results of seven China-6 compliant light-duty vehicles, the global warming potential (GWP), ozone formation potential (OFP), and non-methane organic gases (NMOG) with gasoline, E10, and MTBE10 were calculated and discussed. The GWP of crew-averaged N2O and CH4 emissions were respectively 0.6 and 0.07g CO2e/km. The GWP of non-CO2 greenhouse gases with E10 and MTBE10 fuelling was higher than those of gasoline. Bio-E10 is capable of removing 5%~15% of life-cycle GWP from gasoline vehicles. E10 and MTBE10 both tended to increase benzene hydrocarbon (BHC) emissions and therefore OFP. The NMOG from the test vehicles was roughly 30mg/km. The employment of oxygenated fuels, such as E10 and MTBE10, didn’t result in an obvious increase in NMOG. |
