    Abstract: The present invention relates to a manifold for receiving exhausts from a multi-cylindrical internal combustion engine. The internal combustion engine has such a firing order that the riser in the manifold receives exhausts from two cylinders during an overlapping stage, simultaneously via an inlet opening arranged upstream and from an inlet opening arranged downstream in the riser. The riser comprises a substantially constant cross sectional area, except in one area, which is located in a position in connection with the inlet opening arranged downstream of the two inlet openings, receiving exhausts simultaneously. Said area has a geometry facilitating receipt and flow of exhausts in the predetermined direction in the riser, on occasions when the two inlet openings receive exhausts simultaneously.

    Abstract translation: 本发明涉及一种用于接收来自多圆筒内燃机（1）的排气的歧管。 内燃机（1）具有这样的点火顺序，使得歧管（4a，4b）中的提升器（4a，4b）在重叠阶段期间接收来自两个汽缸（c2，c4，c7，c8）的排气，同时经由 入口开口（3a2,3b3）布置在上游并且布置在设置在立管（4a，4b）下游的入口开口（3a4,3b4）中。 除了位于与布置在两个入口开口（3a，3b）的下游（3a4,3b4）处的入口开口相关联的位置中的一个区域（A，B）之外，立管（4a，4b）包括基本恒定的横截面区域 3a2,3a4,3b3,3b4），同时接收排气。 在两个入口开口（3a2,3a4,3b3,3b4）同时接收排气的情况下，所述区域（A，B）具有便于在提升器（4a，4b）中沿预定方向接收和流动排气的几何形状。

    Abstract: Herein an exhaust manifold (2) is disclosed. A first inlet passage (8) connects to a main passage (12) at a junction. An intersecting wall portion (20) between the first inlet passage (8) and the main passage (12) forms an upstream end portion of the junction. A first portion (22) of the first inlet passage (8) has a first inlet passage cross sectional area (24). The first inlet passage cross sectional area (24) is smaller than a second inlet passage cross sectional area (28) of a second portion (26) of the first inlet passage (8) upstream of the first portion (22) of the first inlet passage (8). The main passage (12) comprises a first main passage portion (30) at the intersecting wall portion (20). The first main passage portion (30) having a first main passage cross sectional area (32). The first main passage cross sectional area (32) is smaller than a second main passage cross sectional area (48) of a second main passage portion (40) upstream of the junction (18).

    Abstract: A method and a device for injection of a reducing agent into an exhaust pipe (2) at a combustion engine, wherein the reducing agent is sprayed in the form of a spray through at least one nozzle (4) toward several evaporation plates (5), arranged in the exhaust pipe section, and which are oriented substantially along a main flow direction (R) for the exhaust pipe section, and each of which has an upstream end section (5'), a downstream end section (5''), a first side (9) and a second side (10). The reducing agent is sprayed toward the evaporation plates' (5) respective first sides (9), constituting the evaporation side between said upstream end section (5') and said downstream end section (5''), which are kept free of spraying. The invention also relates to an exhaust system and a vehicle.

    Abstract: 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 (3a
    1 -3c
    1 ), 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 (3b
    1 -3d
    1 ) 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 (3b
    1 -3d
    1 ). 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.
