Abstract:
A mounting structure of a three-cylinder engine is mounted in a car body transversely but is installed on engine and transmission mounts built on opposing sides in the width direction of the vehicle so that its weight can be supported, wherein a roll mount controls roll moment. The center of mass of the engine and the transmission is the center of rotation where a longitudinal pitch axis, a lateral roll axis and a vertical yaw axis all cross each other, but the roll mount is combined with the engine or the transmission so that the combination point lies on the yaw axis. The mounting structure can improve the NVH performance by suppressing the pitch moment and inducing the yaw moment and by more efficiently insulating the vibration caused by the yaw moment while maintaining the common platform.
