Experimental Study on the Emission Characteristics of a Diesel Engine Using Corn Oil as Fuel

Abstract

The consumption of energy in the form of fossil fuels has been increasing day by day. There is a need to increase energy supplies to meet basic needs and the way that promotes sustainable development. Bio-diesel is an attractive alternative fuel for diesel engines in terms of environmental benefits. In India the production of corn is increasing ever year, the corn oil is extracted from the germ of corn (maize). This paper investigates the emission characteristics of single cylinder diesel engine using biodiesel blends and compares that with diesel fuel. In this experiment, an attempt has been made to investigate four types of fuels are considered 100% Diesel, 90% Diesel+10% Corn oil Methyl Ester, 80% Diesel+20% Corn oil Methyl Ester, 70% Diesel+30% Corn oil Methyl Ester  and 60% Diesel+40% Corn oil Methyl Ester. The diesel engine is run on these blends at different load conditions. The various emission parameters like NOx, Carbon dioxide and Unburned Hydrocarbon are tested with above blends and different load conditions. The experimental results show that the emission parameters for IC engine fuelled with biodiesel blends are less compared to diesel fuel at all the load conditions. 

Keywords
