Study on Vibroacoustic Analysis of Marine Engine Supplied with Mixture of Fuels

August 26, 2021 Chemical and Material Science 0

Various viable possibilities such as biodiesel, hydrogen, alcohols, compressed natural gas (CNG), and liquefied petroleum gas (LPG) are being researched by top crude oil businesses (LPG). The main goal of this study is to compare the vibrations of a Doosan MDT196TI engine fueled by two distinct fuel mixtures: liquefied natural gas with diesel pilot and diesel solo. The combustion temperature, density, and cetane number of LNG and diesel oil differ; the combustion process of various fuels progresses differently, which has an impact on the generated vibroacoustic vibrations (vibrations have a direct impact on the degree of machine degradation). The diagnostic system used in research is based on pizoelectric accelerometers and DSP operations (windowing, Fast Fourier Transform). The conclusions were utilised to interpret the findings, revealing how the tested fuels affect vibrations.
