    • An automotive engine is generally provided with an exhaust gas pipe assembly extending generally rearwardly from the engine for discharging exhaust gases. The exhaust gas pipe assembly includes a plurality of exhaust gas pipes, at least one chamber formed intermediately of the exhaust gas pipe assembly, a first support member disposed in the proximity of the engine, and at least one second support member disposed in the proximity of the chamber. The first support member can effectively absorb relative displacement between the exhaust gas pipe assembly and the vehicle body in a direction transversely of the vehicle body whereas the second support member can effectively absorb relative displacement between the exhaust gas pipe assembly and the vehicle body in a direction longitudinally of the vehicle body. The exhaust gas pipe assembly further includes a dynamic damper disposed in the proximity of the second support member for reducing vibration of the exhaust gas pipe assembly in directions generally perpendicular to the direction longitudinally of the vehicle body.
    • 汽车发动机通常设置有从发动机大体向后延伸以排放废气的排气管组件。 排气管组件包括多个排气管,至少一个室,其形成在排气管组件的中间,设置在发动机附近的第一支撑构件和设置在发动机附近的至少一个第二支撑构件 房间。 第一支撑构件可以有效地吸收排气管组件与车体在车身横向方向上的相对位移,而第二支撑构件能有效地吸收排气管组件与车身之间的相对位移 车身纵向。 排气管组件还包括设置在第二支撑构件附近的动力阻尼器,用于在大致垂直于车身纵向方向的方向上减小排气管组件的振动。
