As a recently introduced method, entrance fuel magnetization, which is obtained from an external magnetic field, is a process through which exhaust gas emissions and fuel supply of internal combustion engines decrease. One of the preconditions of using the magnetized fuel in internal combustion engines is studying about the effects of fuel change on vibration behavior of the engines. Vibration of internal combustion engines can cause failure in engine components and agricultural machinery and vehicle’s drivers upset. In this research, diesel fuel in magnetic fields with different intensities of 1000, 2000, 3000 and 4000 Gauss was studied and Vibration signals of six-cylinder diesel engine (tractor MF-399) at five levels of engine speed and in the longitudinal, vertical and lateral directions were measured and recorded. The results show that the Root Mean Square (RMS) amounts of vibration acceleration were the most in the lateral direction and the least in the longitudinal direction (75.78 m/s2 and 44.59 m/s2 respectively). This research also shows that the RMS amounts of vibration acceleration decrease by increasing the magnetic field intensity and the lowest value of RMS belongs to a magnetic field intensity of 4000 Gauss.
