摘要： Systems and apparatus for muffling sounds produced by an internal combustion engine, and optionally catalytically degrading pollutants within waste exhaust gases. The systems and apparatus utilize a bed of particles within a muffling chamber. The gases are introduced using a diffusion tube with holes therethrough. The muffling particles preferably include silica or alumina, which can also catalytically degrade pollutants. Typically, the muffling/reaction chamber is maintained at a temperature in a range from about 50° C. to about 500° C., which is much lower than temperatures within conventional muffling systems for diesel engines. The muffling systems operate as substantially lower back pressure compared to conventional muffling systems. The systems and apparatus can be adapted to be used in combination with diesel engines or other internal combustion engines and industrial burners.

摘要： To provide a muffler structure capable of lowering muffler cost. A muffler structure is provided in which a sound absorbing material is laid on the inside surface of an outer tube. The sound absorbing material is retained by an inner tube made of a metal that is punched with a plurality of holes. The inner tube is divided into a plurality of expansion chambers. Exhaust gas from an engine is led into the fiat expansion chamber by an inlet pipe. The exhaust gas is discharged out after being supplied to the second and third expansion chambers in succession through the connecting pipes. In the muffler structure, the inner tube is made of an approximately flat metal that is punched with a plurality of holes by bending the metal into circular form until its opposite edges are butted to each other, and is fitted in the outer tube, with the butt portions not jointed, so that the butt portions will come behind the connecting pipe when viewed from the inlet pipe side.

摘要： A catalytic converter for cleaning exhaust gas, particularly from a small engine, includes a converter housing and at least one honeycomb body disposed therein and containing layers of sheet metal having catalytically active material. The converter is disposed on a dividing wall of a muffler housing for a small engine. The dividing wall has at least one opening. The housing has an upper housing component and a lower housing component. The converter housing is shaped in such a way that exhaust gas can flow successively through the honeycomb body and the opening and the converter housing is spaced apart from the muffler housing. Such a converter can be manufactured cost-effectively, can easily be integrated into existing structures and does not lead to unacceptable temperatures of the outer wall of the muffler housing during operation.

摘要： Systems and apparatus for degrading and cleaning combustion products of carbon-containing fuels such as fossil fuels. The systems and apparatus utilize catalytically reactive particles that are at least partially suspended by moving gases within a reaction chamber and maintained at a temperature sufficient to cause the suspended media particles, typically silica sand, silica gel, or alumina, to become catalytically reactive in the presence of moisture. Typically, the reaction chamber is maintained at a temperature in a range from about 30° C. to about 500° C. Moisture may be provided by the waste exhaust, although additional moisture may be introduced into the reaction chamber in order to maintain reactivity of the catalytically reactive particles. The systems and apparatus can be adapted to be used in combination with diesel engines or other internal combustion engines and industrial burners. The exhaust gases containing the incomplete combustion products can be further pressurized as needed. Such systems also reduce nitrogen oxides (NOx), SO2 and CO2 found in exhaust gases.

摘要： A process is provided for filling a muffler shell with fibrous material. It comprises the step of providing a muffler shell comprising one or more muffler shell outer parts which define an internal cavity and an internal structure adapted to extend at least part way through the shell internal cavity and having one or more openings adapted to communicate with the shell internal cavity. The process further comprises the step of providing a bag filled with fibrous material. The bag has a first side with one or more first perforations defining a first side total open area and a second side with either no perforations or one or more second perforations defining a second side total open area. The first open area is greater than the second open area. The process also comprises the steps of positioning the fibrous material-filled bag adjacent the internal structure such that the first side is nearest to the internal structure, and drawing a partial vacuum through the internal structure, the partial vacuum drawing the fibrous-filled bag inwardly towards the internal structure.
