ABSTRACT:
A number of embodiments of internal combustion engine exhaust systems each of which is effective to provide good silencing for exhaust gases through the use of an elastic diaphragm that dampens pulsations. In some embodiments, this elastic diaphragm forms a portion of a Helmholz resonator and in some the diaphragm is cooled by submerging in a cooling jacket of the engine or its exhaust system or by means of cooling air fins. Also, various arrangements are incorporated for adjusting or tuning the rigidity of the diaphragm. Furthermore, in some embodiment the diaphragm is suspended in such a way as to act as a vibration damping member between mechanical components of the exhaust system.
