The first paper described two important points concerning the reduction of engine idling vibration by theoretical approach. The first one was the lower resonance point of a rolling mode and the second one was to prevent a coupled vibration between a lateral and a rolling mode. This second paper shows the optimum design of a 6 mounting points engine model by FEM and the design of experiment, which is so called Taguchi methods. As the most important characteristic is tile lateral acceleration in C. O. G., which is the barometer of coupled vibration with rolling mode, the frequency response analysis is conducted to get it from 0 to 30Hz. As far as the optimization of 18 parameters is concerned, the 216 cases simulations are conducted by the allocation of L36 type orthogonal array. Even though the effect can be obtained by calculation, the bad test results are sometimes occurred by the errors. So, the error factors are also allocated to find out the useful parameters when errors are existing. Finally, nine effective parameters are found out. Among them, the mounting position changes to upward are the most effective. And moreover, by the reflection of the effective parameters, the engine mounting points can be reduced from six to four.
