THE ANALYSIS AND IMPROVEMENT OF DIESEL ENGINE PERFORMANCE USING KARANJA BIODIESEL

Abstract

A renewable fuel that may be used in lieu of diesel is biodiesel, which is one of the best ways to reduce carbon dioxide emissions. This research focuses on the refinement of biodiesel from Pangomia Pinnata oil, often known as karanja oil. Investigated and contrasted with petroleum diesel are the physical and chemical characteristics of Karanja Biodiesel and its blends. Furthermore, the performance attributes of diesel engines that run on Karanja biodiesel were assessed by the use of blends of the fuel (KB5, KB10, KB15, KB20, KB25) that included, respectively, 5%, 10%, 15%, 20%, and 25% of Karanja biodiesel. The power, fuel consumption, and thermal efficiency of the brakes were assessed at various engine speeds while the load remained constant. Additionally, we used Response surface techniques to determine the optimal engine operating parameters in common scenarios.  A CCD framework consisting of three components, five levels, and two blocks was used in the RSM model. Using the Minitab®16.2.1 statistical program's response surface optimizer, each aim was optimised. The ideal values for S (1900 rpm), B (13%), and T (33 N.m.) were found to improve engine performance while minimising fuel usage.
