    • An extendible exhaust system is disclosed for preventing exhaust gas seepage into the passenger compartment of a vehicle utilizing a pipe extender that slides along the tailpipe. The pipe extender has a retracted position and an extended position. The pipe extender moves from the retracted position to the extended position when the vehicle travels forward at a predetermined speed. When in the extended position, exhaust flows through the additional length of the pipe extender before exiting the exhaust system. Movement of the pipe extender from the retracted to the extended position may be by airflow traveling past the moving vehicle pushing on a flange acting as a sail against a tension spring. An electromagnet or motor drive system with a movement sensor may also be used to move the pipe extender from the retracted to the extended position.
    • 公开了一种可扩展排气系统,用于利用沿着尾管滑动的扩管器来防止排气渗入车辆的乘客舱。 扩管器具有缩回位置和延伸位置。 当车辆以预定速度向前行进时,扩管器从缩回位置移动到延伸位置。 当处于延伸位置时,废气在离开排气系统之前流过扩管器的附加长度。 扩管器从缩回位置到延伸位置的移动可以是通过移动的车辆的空气流动而推动抵靠拉伸弹簧作为帆的凸缘。 具有移动传感器的电磁体或电机驱动系统也可用于将扩管器从缩回位置移动到延伸位置。
