Abstract (en)

[origin: EP1288459A2] The exhaust manifold has a pipe elbow with exhaust pipes opening into it. The exhaust pipes (5a) are aligned within the pipe manifold (8), with their triangular ends shaped like a quarter circle segment, and four forming a circle. The free ends of the pipes are connected via a defined edge contact surface (11), while in the remaining areas, the pipes are at a gap (21) to each other. Each edge has a width of approx. 5mm, and the gap has a width of approx. 2mm.
