Definitions
- the invention relates to an exhaust manifold of an exhaust system for a Internal combustion engine according to the preamble of patent claim 1.
- An exhaust manifold with exhaust pipes is known from EP 0 806 598 A1 merged area are interconnected and otherwise angled diverge and do not lie side by side in the same direction. Furthermore, is out US 6,122,911 an exhaust manifold is known in which the merged Exhaust pipes are merged into a segment of a circle and each pipe Form quarter circle segments and the walls of these quarter circle segments only on the corner side lie next to each other and otherwise have a gap.
- the object of the invention is to provide an improved exhaust manifold for an exhaust system to create an internal combustion engine in which noises, in particular rattling noises be avoided.
- the main advantages achieved with the invention are that by Separation of the exhaust pipes as far as possible, especially when they are close lying next to each other and arranged in the same direction, a noise reduction is achievable.
- the exhaust pipes are arranged in the pipe bend in the same direction and form a circular cross section at the ends, the exhaust pipes at the free end on the one hand via a defined peripheral contact surface with each other are connected and on the other hand the rectified exhaust pipes in the further course stand apart from each other with a gap.
- the invention provides in particular that the free ends of the exhaust pipes each opening into the elbow are triangular as quarter-circle segments and each pipe end a relative has a narrow edge, which is compared to the remaining area of the exhaust pipes is projecting outside and there is a gap between the exhaust pipes. This will achieved that the exhaust pipes only at the pipe edge over a relatively narrow area - defined even at different temperatures - lying next to each other and otherwise the pipes are slightly separated from each other via the gap.
- the contiguous Pipe edges are either flat or have beads that interlock to grab.
- the exhaust pipes are exposed or only across a gap arranged and in such a way that the motor side on the mounting flange held exhaust pipes in the exhaust manifold housing with the continuing exhaust pipes are each connected via a sliding seat and that the exhaust pipes from The mounting flange is exposed over the edge until it is received in the elbow are arranged.
- the sliding seat between the exhaust pipes in the housing of the Exhaust manifold causes thermal expansion on the one hand and other possible degradation due to friction between the pipes Vibrations of the exhaust pipes.
- An exhaust manifold 1 of an exhaust system for an internal combustion engine comprises essentially an exhaust manifold housing 2 with an engine-side mounting flange 3 and arranged in the housing 2 exhaust pipes 4 to 7 for one half Eight-cylinder engine. On the housing 2, a pipe bend 8 is connected, the further exhaust pipes 4a to 7a is connected.
- the exhaust pipes 4 to 7 and 4a to 7a run from the mounting flange 3 on the engine to to the inlet opening 10 in the elbow 8, in which it means with its free ends of a raised flat edge 11 are held in an inner tube 12.
- the edge 11 of narrow width a and is above the remaining pipe cross section of the exhaust pipes 4a to 7a so that the subsequent rectified areas of the exhaust pipes to each other have a gap 21 and are arranged at a gap distance b from one another.
- the free ends of the exhaust pipes 4a to 7a are closed at the ends Quarter circle segments 20 formed and together form a cross section Circular opening. These quarter circle segments 20 each have the edge 11.
- Inner tube 12 is arranged, the flange 22 with the outer tube 13th is merged. Between the outer tube 13 and the inner tube 12 is in the area of the edge 11, a spacer ring or a so-called knitted wire ring 14 is provided.
- the engine-side exhaust pipes 4 to 7 are connected to the flange 3, as shown in FIG. 2 shows and are via a sliding seat connection 15 with the subsequent, connected further exhaust pipes 4a to 7a. With this connection, the Exhaust pipes 4a to 7a plugged into the corresponding exhaust pipes 4 to 7, as shown in FIG. 6 shows closer.
- the exhaust pipes 4 to 7 and 4a to 7a are in the mounting flange 3 to Connection in the elbow 8 spaced over the edge 11 in the inner tube 12 arranged to each other or they are in the housing 2 to the wall at a distance laid.
