Impact of Diethyl Ether and Methanol Additives on Combustion Performance and Emission Analysis of Mahua Oil Biodiesel Blends

Abstract

<div class="section abstract"><div class="htmlview paragraph">There are numerous efforts being made to find an alternate fuel to the ones that are being used in modern technologies. The need for an alternative has arisen as a result of the rising price of petroleum products and the escalating demand for energy. In an experimental study, the effects of adding methanol and diethyl ether to mahua biodiesel on the output and emissions of a direct-injection diesel engine were examined [<span class="xref">1</span>]. The objective of this study is to evaluate the performance of a mahua seed oil-based biofuel in a single-cylinder diesel engine. The performance and emissions of the CI engine using Mahua biodiesel are examined in this experimental investigation. The fuels made were virgin diesel (100 percent volume), B5 (95 percent volume, 2.5 percent Mahua oil, 1.25 percent diethyl ether, and 1.25 percent methanol), B10 (90 percent volume, 5% Mahua oil, 3% diethyl ether, and 2% methanol), and B15 (85 percent volume, 10% Mahua oil, 3% diethyl ether, and 2% methanol). Although their characteristics may differ, biodiesel’s common goals are to improve performance, lower emissions, and lower fuel costs. When operating at full load, the B15 Blend’s brake thermal efficiency is almost as high as that of the diesel, and the SFC is 20% lower than it would be with plain diesel. However, B15 blend emissions of HC, NOx, and CO2 are lowered by up to 30%, 10%, and 15%, respectively, but CO emission increased by 22% over clean diesel.</div></div>
