Comparison of Methyl, Ethyl and Butyl Algae Oil in Di Engine

Abstract

The world’s energy situation, whether in developing industrialized countries, while it has meanwhile become common knowledge that today’s main resources such as coal, crude oil, natural gas and even nuclear energy will became scary with next generation, the renewable sources such as hydro, wind, solar and bioenergy are gaining more and more importance. SI engines using natural gas can run at higher compression ratios, thus producing higher thermal efficiency but also increased unburned hydrocarbon (HC) and carbon monoxide (co). Algae oil Derived from algae is considered as good alternative to petroleum fuels. The main aim of the project to test the emission of 4-stroke engine using algae oil  without any fuel mixture for the combustion process. In this project, we used algae oil from algae plant and with various blends like methyl, ethyl, butyl. The ethyl, methyl, butyl is mixed with algae oil through transesterification, blending, pyrolysis, dilution processes. The comparison of performance, thermal efficiency, NOx emission, CO emission, hydrocarbon emission, cylinder pressure etc are calculated in testing engine; however further refinement and optimization of engine, fuel injection, compression ratio, etc in system is needed.
