| Abstract | ||
| Alcohol is a very attractive alternative for fuel. It is a supplemental source to fossil-derived fuels, and has the potential to reduce emissions from motor vehicles. In the present work, the effect of blending alcohol with gasoline fuel on the performance and exhaust emission from SI engine has been investigated. Flame conditions (temperature and speed) have been modeled in addition to cylinder pressure and nitric oxides formation. Isooctane fuel and methyl alcohol have been used with blending ratios of 10%, 20%, and 30% by mass. The obtained results show that flame speed is increased and flame temperature is decreased with increasing blending ratio, since the heat content of alcohol is less than that of gasoline. And cylinder pressure is decreased with increasing blending ratio due to the decrement in flame temperature. And for the exhaust gases, it is shown that increasing blending ratio will decrease CO emissions, which represents an environmental benefit. | ||
