Abstract: This paper focuses on the performance and emission analysis of variable CI engine having biodiesel as alternate working fluid produced from a novel process. Biodiesel prepared from two types of vegetable oils (soybean B15, B20, and Karanja B10) in a novel transesterification process, which involves the single-step production of fatty acid methyl ester (FAME) has been used. This method of fuel production is less time consuming and cost-effective. Brake power, brake mean effective pressure, brake thermal efficiency, and specific fuel consumption are measured under variable load conditions which show almost similar performance trends of various mechanical parameters for the biodiesel as of common diesel fuel. Emission analysis has also been carried out, which shows that there have been decreasing trends of CO and increasing trends in CO₂ and NOX percentage in case of increasing load. A new correlation for thermal efficiency concerning influencing parameters has been developed as well.
