A Review on CNSL Biodiesel as an Alternative Fuel for Diesel Engine

Raghavendra Prasada S. A

Abstract: The world is confronted with serious problems like depleting reserves of petroleum and environmental issues have led to the search for more environmental friendly and renewable fuels. Biodiesel obtained from various renewable sources has been recognized as one of the alternative fuel due to its biodegradability, high cetane number, no sulphur emissions and low volatility. In this paper Cashew nut oil is used as raw material to produce a biodiesel. This paper reviews the preparation of biodiesel from Cashew nut shell oil (CNSL), properties of oil and Biodiesel, performance and emission of cashew nut oil as biodiesel in Compression Ignition engine. Cashew nut oil is one of the most efficient and high productivity Non-edible oil crops. The cashew nut oil blended in varying proportion like 10 %, 20 %, 30 % etc. with diesel fuel in the CI engine. By varying the Compression ratio, Injection pressure, Speed, Load or by using Additives we can check the performance and emission characteristics of biodiesel-diesel blends and finds the most preferable combination of the blend for diesel engine. Based on various studies, this paper generally found that CNSL biodiesel is considered as offering many advantages, including sustainability, decrease of HC, CO, NOx gas emissions and many harmful pollutants.
