| 7 | Engine noise reduction apparatus | US379733 | 1995-01-27 | US5661272A | 1997-08-26 | Francesco E. Iannetti |
| The present invention is a noise reduction apparatus for use in the exhaust system of an internal combustion engine which absorbs acoustical energy from the pressurized exhaust gases while minimizing restrictions on the exhaust gases as they flow therethrough. The relatively unrestricted exhaust gas flow provided by the present invention significantly reduces the build up of back pressure and the associated drop in power and performance of the engine. At the same time, by absorbing acoustical energy from the exhaust gases, the noise level of the exhaust system is reduced. The present noise reduction apparatus includes a housing operatively adapted for being disposed in the exhaust system of an internal combustion engine, and a plurality of generally concentric and radially spaced tubular sections disposed inside of the housing. Each tubular section is adapted with a porous wall which allows exhaust gases to flow therethrough. A plurality of sound absorbing layers are also disposed inside the housing. Each layer is operatively adapted to allow exhaust gases to flow therethrough while absorbing acoustical energy from exhaust gases coming in contact with the layer. Each layer is also operatively associated with one tubular section to allow exhaust gases to flow through the housing, from one end to the other, without having to flow through one of the sound absorbing layers. | ||||||

| Muffler-filter apparatus for reducing both sound and particulates from exhaust gases from an engine. The apparatus includes resonating chambers, flow distribution means and a cellular ceramic core filter module. Filter regeneration mechanism includes a heating element for heating the carbon on the inlet end of the ceramic core to combustion temperature. Particulate ignition resulting in regeneration occurs when combustion air is provided. In alternate embodiments, combustion air first flows through a preheater system. A processor unit with particular logic controls the apparatus. The particular method of regeneration depends on the application in which the muffler-filter is used. | ||||||

| A muffler of the expansion type comprises an inlet pipe and an outlet pipe connected with each other through a main body. Minimization of pressure pulsation is achieved by a variety of means including appropriately-located apertures in those portions of the walls of said pipes within said main body, an apertured partition within said main body so located that exhaust gas passes through said partition, and appropriate tapering of said pipes. A foamed, heat-resistant material may be positioned over said apertures in said walls of said pipes. Pipe constructions suitable for mass production and pipe-to-main body constructions free of the danger of separation during prolonged use are shown. | ||||||

| 14 | Apparatuses and methods for sound absorption using hollow beads loosely contained in an enclosure | US412516 | 1995-03-27 | US5777947A | 1998-07-07 | Krishan Kumar Ahuja |
| A sound absorption device in accordance with this invention includes an enclosure loosely containing hollow beads. Preferably, the hollow beads have openings, and differ with respect to the volume of the hollow space defined by the walls of the beads, the wall thicknesses of the beads, the size of the openings of the beads and/or the number of openings on the beads. Through Helmholtz resonance, vorticity and tortuous path scattering, the beads damp sound waves over a broad range of frequencies. Preferably, the beads are formed from a material able to withstand relatively high temperatures, such as ceramic or nickel. The beads can thus be used to damp sound in applications which generate significant heat in addition to sound, such as aircraft engines, rocket motors or other loud, heat-generating sources, for example. Also, by forming the beads from a material with a relatively low thermal conductivity, the beads can also be used for thermal insulation in addition to sound absorption. | ||||||
| 15 | Insulated damped exhaust manifold | US155688 | 1993-11-22 | US5419127A | 1995-05-30 | Dan T. Moore, III |
| An exhaust manifold for conducting the heated exhaust gas from an internal combustion engine. The exhaust manifold has a thin noncast metal inner layer, a thicker sheet metal outer layer, and a layer of insulating material, preferably ceramic beads, between the inner and outer layers. The method of making the exhaust manifold is also disclosed. The exhaust manifold is damped, insulated, and permits quicker light off of the catalytic converter. | ||||||
| 16 | Engine exhaust muffler | US813533 | 1991-12-26 | US5220137A | 1993-06-15 | Kenneth R. Howerton; Derrell Smith |
| A muffler for muffling engine operating sounds and including a cylindrical shell closed at opposite ends by double-walled closure caps. The space within the shell is partitioned into three axially contiguous chambers. A gas charging pipe projects through one end of the shell and axially within the shell, and has two pairs of facing discharge elbows for discharging gas from the charging pipe at locations in the first of the chambers. A first pair of gas transfer pipes extends from the first chamber into the central chamber to points of opposed gas discharge. A second pair of gas transfer pipes extends from the central chamber into the third or discharge chamber, and from this location, the gas passes out of the muffler via a discharge pipe. | ||||||
