EXPERIMENTAL INVESTIGATION ON A DI DIESEL ENGINE FUELLED WITH BIO OIL (MAHUA OIL CAKE) AND DIESEL

Abstract

Partial or complete replacement of petroleum based fuels for diesel engines has been seriously studied in
various parts of the world. Research on alternative renewable fuels has become very important worldwide due to
concerns about the effects of fossil fuel usage on global warming. They can be made from renewable raw material and
can offer reduction of fossil fuel consumption. Modern diesel engines require a clean burning, stable fuel that performs
well under a variety of operating conditions. Bio oil has become more attractive recently because of its environmental
benefits and the fact that it is made from renewable resources. Bio oil from bio waste based fuels is obtained from limited
reserves. These finite reserves are highly concentrated in certain regions of the world. In the present study, t he bio oil is
obtained from mahua oil cake (MOC). The engine is made to run on diesel and bio oil by various blend ratios of
MOCD5%, MOCD10%, MOCD15% and MOCD20% in a single cylinder, four stroke, water cooled and diesel engine at
1500 rpm. The measured performance parameters are brake thermal efficiency, specific fuel consumption and engine
exhaust emission of CO, HC, NOx and smoke density. NOx emission is lower for MOCD blend
