Assessment of Ethanol as Fuel Additive to Diesel-Biodiesel Blends on Combustion and Performance Characteristics in CI Engine

Abstract

Biodiesel is one of the most promising and technically viable partial replacements to the petroleum diesel. Many research works were carried out on diesel -biodiesel blends focusing on the performance and emission aspects of the CI engine. Diesel biodiesel blends encounter with operational problems like higher viscosity, higher surface tension and less intensity atomization of the burning mixing. These set back in the diesel-biodiesel can be overcome by the addition of the ethanol to the diesel -biodiesel mixture. An attempt has been made to use higher concentration of ethanol by using Karanja biodiesel as medium of mixing with diesel. In this paper discussion has been made on the effect on the performance and combustion aspects of CI engine operating on the Diesel-biodiesel-ethanol blends
