摘要： 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.

摘要： A sound damping apparatus has a resilient wall that defines a first volume and rigid walls defining a second or third volume. A gas entry communicates with the volume defined by the resilient wall. The resilient wall and the rigid walls are in contact such that gas pressure separates the walls and the wall to intermittently define a gas exit between volumes within the wall.

摘要： A sound damping apparatus has a resilient wall that defines a first volume and rigid wall defining a second or third volume. One rigid wall may be a part of the device muffled. A gas entry communicates with the volume defined by the resilient wall. The resilient wall and the rigid walls are in contact such that gas pressure separates the walls and the wall to intermittently define gas passages between volumes. Fluid within the wall surrounding the resilient wall dampens resilient wall vibration.

摘要： An electronically controlled active exhaust-noise attenuation muffler, comprises a loudspeaker serving as a secondary sound source arranged upstream of a tailpipe and communicating with an interior of an exhaust pipe, for attenuating a noise level of exhaust noise produced by the exhaust system by emitting a secondary sound, which is in opposite phase to the exhaust noise, into the exhaust pipe. The tailpipe is formed in a flared-out fashion so that a cross-sectional area of the tailpipe gradually increases towards a downstream end thereof, to reduce pressure loss in exhaust gas flow in the exhaust pipe by radiating the exhaust gas through the flared-out tailpipe. The tailpipe section is a high-frequency exhaust noise attenuation structure to attenuate a high-frequency noise component propagated with a moving stream of the exhaust gases.

摘要： A silencing system for exhaust gases from internal combustion engines, comprising an intermediate silencing device for connection to the exhaust manifold of an internal combustion engine, and a final silencing device series connected to the intermediate silencing device, in which the final silencing device comprises, within an envelope, a number of spaced annular members, intersected by radial partition walls, forming series of chambers of different size, which occupy the peripheral portion of the envelope and open towards the axial portion of this latter, leaving this axial portion substantially free for passage of the flow of exhaust gases, and an idle fan is provided for acting onto the passage for the exhaust gases and onto a passage for additional air, which passages join downstream the fan into an exhaust nosepiece. Some annular members are made of a catalytically active material in order to exert a purifying action on the exhaust gases.
