Analysis the Performance, Emission and Combustion of DI Diesel Engine Powered By Algae Methyl Ester

Abstract

This paper reports on the algae methyl ester is blended with diesel fuel in different
percentage and the effects of their performance, combustion and emission characteristics of the
DI diesel engine. In this study, the tested fuels were obtained through transesterification process.
The properties of algae methyl ester (AME) analysed by ASTM standard methods. Experimental
results showed that the cetane number and flash points of the algae methyl ester blended diesel
have increased with higher concentration of AME. Based on the experimental results, HC and
smoke emissions noticeably increase, while NOx emissions significantly decrease with
increasing the dosing level of AME. From the results, B25 having nearer values in terms of
combustion and emission to diesel fuel. At the full load, the magnitude of HC, smoke and NOx
emissions for the neat diesel was 114 ppm, 72 HSU and 1120 ppm, whereas it was 116 ppm, 79
HSU and 1070 ppm for the B25 blend of AME fuel, respectively.
