Experimental Investigation on Injection Parameters by varying Compression Ratio Using Fish Oil Biodiesel in Diesel Engine
Punith Kumar , Harish H
Biodiesel synthesized from various vegetable and animal fat oils has proven as a potential resource and shown neutral effect on environmental pollution. The feedstock fish oil has been explored for the synthesis of Biodiesel through Transesterification from sodium hydroxide catalyst. Investigations carried out with bio-diesel operation in a single cylinder diesel engine. The performance and emission characteristics of fish oil bio-diesel compared with ordinary diesel in a diesel engine under varying load and results for various combinations of diesel and Fish oil bio-diesel with blends B-20, and B-30, parameters like total fuel consumption, brake specific fuel consumption, brake thermal efficiency are calculated and tabulated. Based on the results obtained graphs are plotted to compare Performance parameters. Speed conditions of engine operations are fish oil bio-diesel shows higher fuel consumption rate, kinematic viscosity, brake fuel consumption. Most of the major exhaust pollutants such as CO, CO2 and HC are reduced with the use of bio-diesel and the blend as compared to neat diesel. The exhaust gas temperature increases by increasing the blends as compared to neat diesel. Among the blends, B30 shows the better performance and emission characteristics. Results obtained at compression ratio 17.5 and injection pressure 200bar showed better performance characteristics when compared with others. In terms of fuel properties and exhaust emission characteristics, ?sh oil bio-diesel can be regarded as an alternative to diesel fuel.
