摘要:
An exhaust muffler 10 includes an expansion chamber 11 into which engine exhaust gas is introduced, and a sound deadening element 13 inside the expansion chamber 11. The sound deadening element 13 is configured from a knitted article formed by knitting continuous fibres of glass fibre. The exhaust muffler 10 further includes an inner pipe 17 spaced from an inner circumferential wall 26 of the expansion chamber 11 and configured so that the exhaust gas can be introduced therethrough. The sound deadening element 13 is disposed between an outer circumferential wall 23 of the inner pipe 17 and the inner circumferential wall 26 of the expansion chamber 11. This provides an exhaust muffler in which the anti-scattering property of a sound deadening element is high and where shaping of the sound deadening element is not required. The invention also extends to the sound deadening element itself.

The present invention aims at smoothly lifting up an exhaust gas purification device (2) in the case of assembling the exhaust gas purification device (2) in an engine (1). The exhaust gas purification device (2) of the present invention is provided with a plurality of filter bodies (43, 44) which purify exhaust gas discharged by the engine (1), and a purification casing (40) which has each of the filter bodies (43, 44) built-in and is constructed by a plurality of purification cases (47, 48, 51). The purification casing (40) is constructed by arranging each of the purification cases (47, 49, 51) in an exhaust gas moving direction and connecting the purification cases by thick plate flanges (59, 60, 73, 74). A suspension body (101) is integrally formed in the thick plate flange (73).
摘要:
A pollutant reducing exhaust manifold for an internal combustion engine incorporating a catalytic converter therein. The manifold has a plurality of header pipes connected to and receiving exhaust gases from respective ones of a plurality of exhaust ports of an internal combustion engine. The header pipes are connected to a single chamber with an outlet therefrom connected to an exhaust pipe as well as a catalytic converter structure having a catalyst disposed on a supporting substrate disposed in the chamber between the inlet(s) and the outlet so that all exhaust gases from the engine must pass through the catalytic converter structure. The catalytic converter operates at higher temperatures for increased efficiency and comes to operating temperature virtually immediately.
摘要:
An exhaust pipe structure includes a first exhaust pipe (21), a second exhaust pipe (44) and a coupling member (3). The coupling member (3) couples the first exhaust pipe (21) and the second exhaust pipe (44) via an opening (34) of the coupling member (3). The coupling member (3) has a groove (35) extending toward the opening (34) along an outer edge portion of a surface (facing the inside of the first exhaust pipe (21)) of a bottom plate portion (33) shaped to correspond to a region where the first and second exhaust pipes (21, 44) overlap each other.
摘要:
A component of an exhaust system may convey exhaust gas between one or more inlets and one or more outlets and may include at least one fluid path in thermal communication with the exhaust gas. The fluid path may be defined by an external surface of the component and a cover plate attached to the external surface. The fluid path may be connected to a coolant source.
摘要:
Exhaust muffler for internal combustion engines comprising at least two portions of external shell (1,2) reciprocally joined along perimeter edges (3) and internal separators (4) in one-piece with at least one of the portions of external shell to form chambers (5,6,7) and/or connecting pipes (8,9) fit to allow the passage of the exhaust gases from an entry section, or opening (10), to an exit section, or opening (11), for the exhaust gases.
