Abstract (en)
[origin: WO2013058700A1] The present invention relates to a manifold for receiving exhaust gases from a multi-cylinder combustion engine (1). The manifold comprises a common line (4), a first branch line (3a-c) adapted to receiving exhaust gases from a first cylinder (2a-c) and to leading them into the common line (4) via a first outlet aperture (3a1-3c1), and at least one second branch line (3b-d) adapted to receiving exhaust gases from a second cylinder (2b-d) and to leading them into the common line (4) via a second outlet aperture (3b1-3d1) situated downstream of the first outlet aperture with respect to the intended direction of flow of the exhaust gases in the common line (4). The manifold is provided with a guide element (7) which protrudes into the common line (4), thereby reducing the cross-section for the flow of exhaust gases close to the second outlet aperture (3b1-3d1). The guide element (7) has running through it at least one hole (7c), the size of which is such that part of the exhaust gases in the common line (4) which reach the guide surface (7a) passes through said hole (7c). The invention relates also to a combustion engine provided with such a manifold.
