Definitions
- the invention relates to a double-flow exhaust system for an internal combustion engine according to the preamble of claim 1.
- each exhaust line consists of several assemblies, such as exhaust manifold, catalytic converter and rear silencer, which are assembled via corresponding exhaust pipe lines and flange connections.
- the object of the invention is to design the assemblies of the exhaust system in such a way that on the one hand the space available in the area of the exhaust pipe is increased and on the other hand the assembly of the entire exhaust system is facilitated.
- the two exhaust lines each have a separate rear silencer, both of which are connected in terms of fluid technology via at least one mountable connecting pipe, means that the installation space obtained between the two end faces can be used for the placement or configuration of the exhaust pipe.
- the two exhaust lines in the area of the rear silencer, it is possible to assemble the individual exhaust lines as a pre-assembled unit in order to then complete them on the vehicle to form the overall exhaust system.
- the U-shaped exhaust system in the area of the rear silencer it is also possible to transport the pre-assembled unit without any problems. Due to the features and measures listed in the subclaims, further advantageous refinements and developments of the exhaust system are possible.
- a first connection of the two rear silencers takes place via a T-pipe section, which is connected with its two first pipe ends to the two rear silencers, while the third pipe end serves as an exhaust gas outlet.
- a T-pipe section which is connected with its two first pipe ends to the two rear silencers, while the third pipe end serves as an exhaust gas outlet.
- an end pipe with an end pipe cover is mounted on the third pipe end of the T-piece.
- a second connecting pipe between the two rear silencers advantageously contributes to noise damping, particularly of the low-frequency components in the lower speed range.
- noise damping particularly of the low-frequency components in the lower speed range.
- a torque increase in the lower speed range is achieved.
- the course and the position in the speed band of the torque increase and the noise damping can be significantly influenced by the specific coordination of the pipe length and the pipe cross-section.
- the mountable second connecting pipe consists of two pipe sockets connected to the respective rear silencer housing, onto which a sliding sleeve is pushed and their axial positioning or securing e.g. can be reached by a clamp.
- Fig. 2 is a front perspective view of the exhaust system
- Fig. 3 is a rear perspective view of the exhaust system.
- the two-flow exhaust system for a 6-cylinder engine each has an exhaust manifold 2 and 4, each of which is attached with its flange section 6 or 8 to the cylinder head of an engine unit, not shown.
- the three individual pipes of the exhaust manifold 2 and 4 open into an exhaust gas collection pipe 10 or 12, to which a housing 14 or 16 of a starting catalytic converter is connected.
- An exhaust pipe 18 or 20 is connected to the two starting catalytic converters 14, 16 via a releasable flange connection 19, each leading to a housing 22 or 24 in which a main catalytic converter is accommodated.
- the two main catalytic converters 22, 24 are each received in a rear silencer housing 26 or 28 or partially integrated therein.
- Both rear silencer housings 26 and 28 are connected to one another via a first connecting pipe 30, hereinafter referred to as the lower connecting pipe.
- the lower connecting pipe 30 is designed as a T-pipe piece, on the free connecting piece of which an exhaust pipe cover 32 is fastened, while the two connecting pieces are plugged onto a pipe connecting piece of the respective rear silencer housing 26, 28 and are secured by two fastening clamps 34.
- a second connecting pipe 36 hereinafter referred to as the upper connecting pipe 36, runs above the lower connecting pipe 30 and consists of two pipe sockets 36 a and 36 b led out of the respective rear silencer housings 26 and 28. The two ends of the pipe sockets 36a, 36b are spaced apart from one another in an aligned manner on the end faces.
- the gap a which forms is covered by a sliding sleeve 36c (only shown in FIG. 1), which is secured axially with the aid of clamping clips, not shown.
- a second gas-tight connection between the two muffler housings 26 and 28 is thus produced through the connecting pipe 36.
- a fastening device 38 is provided for suspending or fastening the entire exhaust system, which has a carrier plate 40 that can be fastened to a transmission.
- a lower tubular strut 42 is fastened to the carrier plate 40, on the left and right support legs 42a and 42b one of the housing of the Starting catalyst 14 or 16 encompassing fastening clamp 44 or 46 is provided.
- the lower tubular strut 42 is supported by two tension struts 48 and 50 which are elastically mounted on the carrier plate 40.
