Abstract
The invention discloses an exhaust connecting pipe assembly which comprises an exhaust connecting pipe body, and an air inlet and an air outlet that are positioned at the two ends of the exhaust connecting pipe body, wherein an exhaust bellows is arranged at a front section of the exhaust connecting pipe body. The exhaust bellows is a flexible pipe, and can isolate vibration transferred to an exhaust system by an engine, so that resonance caused by the vibration which is transferred to an automobile body and coincided with the inherent frequency of the automobile body can be avoided. When the exhaust bellows isolates the vibration of the engine or a power assembly, the vibration amplitude of the front section of the exhaust system is reduced, so that regenerated noise is avoided. With the adoption of the scheme, the stability and the reliability of the exhaust system are improved, the service life of the exhaust system is prolonged, and the riding comfort is improved. The invention also provides an automobile and the engine comprising the exhaust connecting pipe assembly.
