A REVIEW ON THERMAL ANALYSIS ON FOUR STROKE C.I ENGINE USING BIODIESEL (COTTON SEED AND MAHUA)

Abstract

Diesel engines are widely used in light, medium and heavy duty vehicles and power generation in heavy machinery, because of higher thermal efficiency and the ability for lean operation. Further, the lean burn capability helps to lower the carbon monoxide (CO) and Hydro carbon (HC) emissions compared to those of a spark ignition (SI) engine. However the emission of oxides of nitrogen (NOx) and particulate matter are higher in a diesel engine. Bio-fuels, due to their agricultural origin, are able to reduce net carbon dioxide (CO2) and CO emissions. Bio-fuels are having environmental benefits as they are made from renewable sources. Bio-diesel is biodegradable and it can be used in most diesel engines with minimum alterations in the engine manifold. In this paper Cotton seed and Mahua oil is used as raw material to produce a biodiesel. This paper reviews the Production of biodiesel from Cotton seed and Mahua oil, various properties, performance and emission of Cotton seed and Mahua biodiesel in compression ignition (CI) engine. Non edible and edible biodiesel blended with diesel were tested for their use as substitute fuels for diesel engines. This oil is blended in varying proportion like 10%, 20%, 30% etc. with diesel fuel and by varying the Compression ratio, Injection pressure, Speed, Load or by using Additives we can check the performance and emission characteristics of biodieseldiesel blends and can find out the most preferable combination of the blend for CI engine. Based on various studies, this paper generally found that Cotton seed and Mahua biodiesel can be used in CI engines as alternative fuel.
