Abstract
Renewable and environmentally friendly biodiesel is a fuel that can provide comparative engine performance. The diesel engine performance, noise, and vibration parameters were studied. Vibration and noise production due to the combustion of fuel in engines have a direct effect on engine performance. Therefore, in this paper, the study of three different vibration parameters — mainly displacement, velocity, and acceleration — was carried out with both diesel and biodiesel blends. A Kirloskar-made single-cylinder, 4-stroke, water-cooled, 3.5 KW at 1500 rpm diesel engine with a water-cooled eddy current dynamometer was used. The output vibration parameters were measured using a vibrometer, engine noise by a noise meter, and other measuring instruments. The testing of the engine was carried out at different loads as per the orthogonal array obtained by Minitab from the input parameters. The orthogonal array selection was based on three parameters and four levels for each parameter. The experimental output conditions with optimal input parameters — blend B15, applied load 7 kg, compression ratio 18 — are vibration parameters such as Displacement 0.458 mm, Velocity 23.68 mm/s, and Acceleration 345.5 m/s². The regression plot for acceleration obtained by Taguchi is compared with the ANN regression plot. There is a similarity in these plots; hence results are validated by ANN.
