Performance and Emission Analysis of a Compression Ignition Engine Using Different Biofuel Blends

Abstract

Existing internal combustion engine (I. C. Engines) systems produces hazardous pollutants like CO, CO2, NOx, SO2, Soot etc with gasoline and diesel as a fuel. it causes problems like global warming.  It is also dangerous to lives of human beings and other living organisms on earth. Hence researchers are trying to study the performance of I. C. Engines with different blends of biodiesels like B05 (5% biodiesel with 95% pure diesel), B10 (10% Biodiesel with 90% pure diesel), B15(15% biodiesel with 85% Diesel) And B20(20% biodiesel with 80% pure diesel), in order to improve the performance of I. C. Engines in terms of different pollutants like CO, CO2, NOx, SO2, Soot etc. In the current work the performance of a four-stroke diesel engine is studied with different blends of biodiesels like B05, B10, B15 and B20. Performance results shows that most of the biodiesel, give higher brake thermal efficiency and lower brake-specific fuel consumption. Emission results showed that in most cases, NOx is increased, and HC&CO emissions are decreased. It is found that B20 blend is better amongst other blends in terms of emission characteristics.
