A Comparative Study and Tribological Analysis of IC Engine Using Alternative Fuel

Abstract

The ever-growing demand for fossil fuel and its scarcity at the same time made researchers dig more on the development of alternative fuels. Alternative fuels can be ethanol, methanol, naphtha, oils derived from vegetables or from animal fats, etc. In this review paper, a comparative study is attempted to see the effect of alternative fuel derived from Karanja on performance, emissions and tribological study including ferrography test, wear analysis, lubricating oil analysis, atomic absorption spectroscopy, surface roughness, etc on CI engine by different authors with respect to standard diesel. The biofuels can be directly injected into the IC engine without any engine modification. Improvement in BTE and BSFC/BSEC with the use of Karanja with less emissions except for NOx. Improvement in the properties of the alternative fuel is done by the use of additives. The tribological analysis is done in the long run of engines. Less wear is observed with Karanja biodiesel but increased in the case of 20% blend. A table is formed showing comparative study on performance, emissions and wear analysis of CI engine run with alternative fuel derived from Karanja compared to standard diesel.
