Utilizing Diesel and Biodiesel Blends from Pongamia pinnata (L) Pierre Seeds for CI Engine Exergy Analysis

Abstract

Exergy is the greatest theoretically useful work that can be achieved while a system interacts with an equilibrium state. Energy analysis is used to understand and enhance the actual efficiencies of the entire system because it is not sufficient to just specify the greatest efficiencies of any given system. The energy analysis was able to detect the energy losses but was unable to pinpoint the location or irreversible losses. The energy analysis makes it easy to identify these losses. In this study, a single-cylinder, naturally aspirated, direct-injection, compression-ignition engine running on diesel, biodiesel, or a combination of diesel and biodiesel underwent energy and exergy evaluations. The goal of this investigation will be to determine whether there is a significant change in engine efficiency when employing different samples of diesel and biodiesel blending from the pongamia pinnata (L) Pierre. Using the data from the experiment, the engine's efficiency, cooling water, exhaust gas exergy losses, and fuel exergy are all reached under steady state conditions. As a result, the tested biodiesel and petrodiesel fuel showed comparable energy performance.
