- Abstract
Use of biodiesel in compression ignition engine is widely recognized due to its reduced exhaust emissions, enhanced carbon dioxide cycle, less toxicity and improved safety. Biodiesel derived from vegetable and biological sources encompasses a substantial quantity of saturated FFA, which leads to increased kinematic viscosity. The present work aims at comparing the feasibility of using the methyl esters of cottonseed and alga (Stoechospermum marginatum) oil separately in a compression ignition engine. The bio-oils were transesterified through base catalysed transesterification using methanol and potassium hydroxide as catalyst. Addition of n-butanol up to 10% improves the physico-chemical properties of fuel, thereby promoting enhanced combustion. The test fuels were formulated on analysing their stability through Taguchi’s approach in design of the experiments. The L9 orthogonal array show cast a stable blend as mineral diesel 80%, biodiesel 20% and n-butanol oxygenate 10% for 21 days without precipitation. The performance and emission analysis of the test fuel blends showed higher brake thermal efficiency with lower brake specific energy consumption for algal biodiesel blends. The oxygenated blends of algal biodiesel emitted lesser carbon monoxide, hydrocarbons and smoke in comparison with cottonseed biodiesel.
