Attributable to its comprehensive advantages of good vibration isolation performance and low cost, air engine mount is gradually being applied in vehicle powertrain vibration reduction. In the present paper, a full vehicle nonlinear model considering air engine mount was established to describe the characteristics of engine shake better. A Jacobian-free Newton-Krylov (JFNK) method for solving nonlinear equations was proposed to simulate the model more efficiently. The result demonstrated that air engine mount has great influence on engine shake characteristics under the front wheel excitation. Then the influence of air engine mount parameters on engine shake characteristics was discussed. Finally, the engine shake characteristics considering air engine mount and hydraulic engine mount were compared and the result showed the former resonance frequency was higher.
