چکیده	The vibration of self-propelled machinery must be controlled as a drawback of them. The goal of the present research was to assess the vibration of four-stroke single-cylinder diesel engine of an agricultural tiller under the effect of magnetized biodiesel-diesel fuel blends. Biodiesel was consumed as a renewable fuel which is recycled from agricultural and food industry wastes or as the main product of oilseeds. Fuel magnetizing was applied as a new method to enhance the combustion process. A factorial experiment based on completely randomized design by conducting 12 treatments at three replications was doen on the engine. Two main factors were tested including biodiesel fuel (B0, B5, B10, and B20) and magnetic field (M0, M5300, and M7000). Engine vibration was measured at Z direction using VB 8203 accelerometer. The statistical analysis indicated that the main factors and their interactions had significant effects on vibration of the engine at 1% probability level. The root mean square of vibration was decreased by applying the magnetic fields. The data analysis in the frequency domain approved that the highest amount of vibration was observed in the tests without using magnetic field and the lowest root mean square was obtained for all blends with 5300 G magnetism intensity.
