Investigation of cottonseed oil biodiesel with ethanol as an additive on fuel properties, engine performance, combustion and emission characteristics of a diesel engine

ABSTRACT
In last few years in automobile sector there is a emerging need of an alternative fuel because of depletion of the stock of fossil fuels in all over the world. Biodiesel in this regard contested a strong alternative to the conventional fuels. Biodiesel contains 9 to 10% higher oxygen and higher cetane number which allows its good combustion in the combustion chambers of the engine. But poor hot flow and cold flow properties of biodiesel restricts their applications in the field of automotives. So the blends of biodiesel in percentage with diesel and ethanol as an properties enhancer additives are used in the biodiesel/diesel blend. Reduced viscosity, higher calorific value, improved flash and fire point and enhanced cold flow properties of the blends with ethanol as an additive, enhanced the combustion and reduced harmful emissions from the engine. Experimental work presented in this paper is by considering cottonseed biodiesel as raw feedstock blended with diesel and 5% ethanol. Properties were investigated experimentally as per IS 1448 standards. Trials were conducted on the single cylinder diesel. Results show that there are significant improvements in the properties of the blend, performance, combustion and reduced harmful emission from the engine. Experimental investigation reported that ethanol as an additives in the blends of cottonseed biodiesel with diesel reduces kinematic viscosity by 7% , cold flow properties by 9% to 10% . But on the other hand but density of the blend is increased by 3% and higher heating value is decreased by 9%.
