Energy Saving and Pollutant Emission Reduction by Adding Hydrogen in a Gasoline-fueled Engine

Pollution reduction related to combustion engines is considered be an important issue around the world. Hydrogen as additive energy has been utilized for alternative fuel since it need not require any modification. Particularly, a sustainable option diminishing petroleum dependence and air pollutant emissions. In this study, we investigated tailpipe emission with hydrogen addition different driving behavior such cold-start, idle, urban (UDC) extra-urban (EUDC) under New European Driving Cycle (NEDC). The results showed that could attribute most emissions in comparison high speed mode. enhanced process average rates were observed 21.6% 65.8% hydrocarbon (HC), 2.37% 85.4% carbon monoxide (CO), 7.53% 59.3% nitrogen oxides (NOx) when run at UDC EUDC, respectively. wide flammability of ensures homogeneous fuel-air mixture complete reduces HC, CO NOx It noteworthy starting less amount greatly decrease HC followed by NOx. Compared conventional gasoline (G0), consumption was reduced 1.3% small applied fuel.
