The vibration sources of a fourcylinder engine are analyzed using MATLAB and ADAMS codes. Firstly，the main vibration excitation sources of this engine, the second order reciprocating inertia force and the overturning moment, are gained through theoretical analysis. The characteristics of the excitation sources are investigated in both time domain and frequency domain using MATLAB code. Afterwards, the finite element model of the engine is built and the dynamic simulation is performed using ADAMS code. Then, in the postprocessing, using the measured signals in the properly selected positions，types of the main vibration excitation sources and their characteristics in both time domain and frequency domain are gained. The results from the two codes are found to be in good accordance with each other. Thus, the validity of the two methods is verified. The results gained in this paper provide some necessary data for vibration control of engines.
