Abstract :
More stringent emission norms and the need to conserve fossil fuel depletion have forced the researchers to
focus their attention towards the usage of alternative fuels. Also the utmost priority lies in protecting the environment
from transportation emissions. To overcome these problems, gaseous alternative fuels which had proven effective
are being sought after. Among the renewable energy sources, gaseous alternate fuels offer a promising opportunity
for sustainable development in the energy and transportation sectors. The following work discusses the different
gaseous alternative fuels available for SI engines. The use of Hydrogen, Biogas, CNG, LPG, and Syngas in SI
engines is being reviewed. This paper contains information regarding the application of syngas in SI engines and
comparison of Syngas with the other gaseous fuels.
