Vibration analysis of a diesel engine using biodiesel and petrodiesel fuel blends

► We measure the vibration for different blends of biodiesel in a diesel engine. ► Engine vibrations were studied before and after the services. ► The main goal was to present fuels with the minimum vibrations. ► The total vibration values are reduced about 12% after the service of engine. ► It was demonstrated that B40 and B20 had the lowest vibration.
