  • Abstract The emission tests in a dynamometer were conducted under the steady-state cycle condition with different vehicle speeds (Idling, 40 km/hr, 70 km/hr and 100 km/hr) and two driving cycles (FTP75 and NEDC) in a gasoline engine using different inflow rate of hydrogen for understanding the reduction of pollutants and fuel consumption.
    Experimental results showed that the emission factors of traditional pollutants (THC, CO and NOx) decreased with the increasing of hydrogen flow rate (2 lpm-8 lpm) at the idling cycle test. For the low-speed urban driving (40 km/hr), results showed the reductions of pollutants were comparatively better at the 4 lpm of H2, and the best reduction percentages were 66.8%, 92.6%; but NOx emission increased. For the high-speed suburban (70 km/hr) and highway (100 km/hr) driving tests, the emission factors of THC and CO reduced while H2 increased.
    For the driving cycle tests (FTP75 and NEDC), the average emission factors of THC and CO reduced with the increasing of H2 (0.6 lpm and 1.2 lpm), and emission factor of NOx reduced at the 0.6 lpm of H2.
    The consumption of gasoline reduced by 42.2% at idling test when H2 was added. However, the reduction of fuel consumption was insignificant under the speed of 70 km/hr and 100 km/hr. Results of driving cycle tests under FTP75 and NEDC procedures also indicated that reduction of fuel consumption was insignificant with the addition of H2.
