Internal combustion engine (ICE) vibrations not only affect vehicle noise, but also affect vehicle ride comfort. In order to analyze the performance of two types of hydraulic engine mounting system (HEMs) on a passenger car, a full vehicle dynamic model with 11 degrees of freedom is established under the combination of two excitation sources such as the ICE and road surface excitations. The characteristics of HEMs with an inertia channel and a decoupler membrane (HEM 1) were investigated and analyzed for its ride performance compared to HEMs with multi-inertia channel and a decoupler membrane (HEM 2) according to the international standard ISO 2631–1. The achieved results have shown that the values of the objective functions with Type 2 decrease compared to Type 1 under different survey condition. In addition, the research results are the theoretical basis for controlling for multi-inertia channel MRF (magnetorheo-logical fluid) mount.
