Noise and Vibration Analysis of Diesel Engine fueled using Diesel and Neem Biodiesel with Inclusion of MoO3 Nano Particles

Abstract

Abstract: Biodegradable, renewable, and environmentally friendly oxygenated fuels will replace fossil fuels. A single-cylinder, four-stroke, variable compression ratio, compression ignition engine was tested for performance, combustion, emission, and vibration. Biodiesel from inedible neem, which contains 30–45% wt oil, may replace traditional liquid fuels. This work esterified and transesterified methanol and triglycerides at a 7:1 molar ratio to extract biodiesel at 96% volume. This research uses diesel and neem methyl ester (NME) at 50, 75, and 100 ppm. Engine testing at 1500 rpm and 15:1 compression ratio are performed under various loading circumstances. The vibration levels were reduced for 75 ppm inclusion of MoO3 in biodiesel blends when compared with diesel fuels. As the load increased vibrations observed were at maximum.
