Investigative Analysis of Thumba Biodiesel Blends in a Single Cylinder Four Stroke IDI CI Engine at Varying Loads

The present study investigates the performance (BThE) and emission (UHC, NOx) of Thumba biodiesel at varying load percentages with respect to diesel. The experiment was conducted in an IDI CI engine at 34, 67, and 100% load conditions at constant 1500 rpm. Totally, three blends were used for the experiment. The first blend was 100% diesel (PD), the second blend was Thumba biodiesel 10% diesel 90% (Blend 1), and the third blend was Thumba biodiesel 20% and diesel 80% (Blend 2). The experimental result of both biodiesel blends was compared with diesel. From the experimental result, it was found that both the biodiesel blends showed comparable results of BThE, But UHC was lower for the blends whereas NOx was higher for both the blends compared to diesel. From the experimental work, it was also found that the Blend 1 (Biodiesel containing Thumba biodiesel 10% and Diesel 90%) had better results than Blend 2. Also, Blend 1 showed comparable results to diesel.
