Definitions
- the invention relates to an internal combustion engine having a plurality of combustion chambers in the form of cylinders, in which an air / fuel mixture can be converted in a combustion reaction and which are bounded by a common cylinder head, wherein each combustion chamber is associated with an outlet channel formed in the cylinder head and a plurality of outlet channels in the region of an outlet scraper into a common confluence area.
- DE 101 41 534 A1 discloses a cylinder head for a multi-cylinder internal combustion engine in which a plurality of outlet channels extend from outlet openings of the combustion chambers.
- the exhaust ducts unite in a confluence area which is substantially completely integrated into the cylinder head in such a way that it is carried out in one piece with the cylinder head and is delimited by cooling water ducts in the area of an upper side and in the area of an underside.
- a mounting surface is provided for a catalyst, which is thus installed screwed directly to the cylinder head.
- Such a configuration achieves a particularly extensive heat exchange between the cooling water in the cooling water channels and the exhaust gas in the confluence area, but it results in a complicated and complicated cylinder head design, which is also cost-intensive feasible.
- the object of the invention is in contrast to provide a particularly simple means an exhaust manifold, the heat transfer behavior is favorable.
- the internal combustion engine has a plurality of combustion chambers in the form of cylinders in which an air / fuel mixture can be exothermically converted and which are delimited by a common cylinder head, wherein each combustion chamber is assigned an exhaust duct formed in the cylinder head and a plurality of exhaust ducts in the region of an exhaust manifold into a common confluence area.
- the inventive internal combustion engine includes a common confluence region for exhaust gases, which is bounded on a first side by at least one wall of the cylinder head and on a second side by a separate, externally attached to the cylinder head shell element, the shell element for guiding the exhaust gas flow at least partially funnel-shaped and / or warmthenformig curved executed.
- a plurality of outlet channels are provided on the first side of the common confluence region, which are embodied as components of the cylinder head in one piece, in particular by casting methods, and join into the common confluence region.
- a trough-shaped recess is provided on the outside of the cylinder head, which is preferably bounded or defined by a plurality of single-walled walls of the cylinder head.
- the trough-shaped depression is sealed off by means of the shell element to the outside, so that between the depression on the part of the cylinder head and the shell element results in a volume of space in which a plurality of exhaust gas streams can be combined and deflected. This volume of space is thus formed partly within the cylinder head and partly outside the cylinder head.
- a mounting flange for the sealed fastening of the shell element to the cylinder head and an outlet opening with a pipe flange for mounting exnes exhaust pipe or an exhaust gas purification unit are provided on the shell element on the one hand, mounting flange and pipe flange having different dimensions.
- the substantially annular mounting flange defines a planar or curved separating plane between the cylinder head and the shell element, wherein the parting plane passes through the geometric area or the volume of space and subdivides it geometrically.
- the pipe flange is designed to be smaller than the mounting flange, at least with regard to a geometric dimension, in particular with regard to a maximum transverse extent and / or its diameter and / or the flow-through cross section.
- Figure 1 a section schematically represented by a cylinder head of an inventive internal combustion engine with an exhaust manifold and
- Figure 2 a perspective view of the cylinder head.
- Figure 1 shows a horizontal section through a cylinder head of an inventive internal combustion engine, which has six cylinders in two separate, V-shaped arranged cylinder banks, in which an air / fuel mixture can be relegated under pressure and heat release.
- the combustion can be carried out using the diesel process, the gasoline process or a similar combustion process.
- three cylinders have three combustion chambers which are delimited by a common cylinder head 1, which is preferably produced in a single-piece casting process.
- Each combustion chamber is assigned to two outlet channels 2 formed in the cylinder head 1, which can be closed in a manner known per se by way of exhaust valves (not shown).
- the outlet channels 2 are preferably curved in the direction of the downstream exhaust pipe and are positioned closely adjacent to a cylinder head fitting and / or closely adjacent to lubricating oil return bores.
- the described plurality of six outlet channels 2 of a cylinder bank is assigned a common confluence region 3a in the region of an outlet manifold 3, in which the exhaust gas streams guided through the outlet channels 2 are combined.
- the common confluence region 3 a is bounded on a first side A by a wall 1 a of the cylinder head 1.
- the wall Ia of the cylinder head is designed substantially tannenform or pot-shaped and surrounded annularly by a mounting surface Ib.
- Within the wall 1a passages are formed to the outlet channels 2, which are arranged starting from a along the annular mounting surface Ib to be defined, non-annular separation surface T reset.
- the confluence region 3a is provided by a separate, externally attached to the cylinder head.
- limited shell element 4 is limited as part of the Auslasskrummers 3 the confluence region 3a to the outside.
- the shell element 4 is preferably made of a temperature-resistant metal sheet, in particular made of a steel sheet, or as a metal casting and executed at least partially funnel-shaped and / or trough-shaped curved. Its simple shape allows a particularly simple and inexpensive production of the shell element.
- the shell element has a circumferential annular groove which engages in the area of the trough-shaped mounting surface in the cylinder head.
- the shell element is designed double-walled.
- the shell element is made comparatively narrow, whereby the seal between the cylinder head and the shell element is improved.
- the shell element 4 has, in particular detachable fastening by means of screws on a mounting flange 4 a, which is designed adjacent to the mounting surface Ib. Between the mounting surface Ib and mounting flange 4a thus one or more preferably annular sealing elements are used, which come to lie in the parting plane T.
- a pipe flange 4b is provided on the shell element 4, the through-flow cross-section of which differs from that of the mounting flange 4a with respect to essential geometric dimensions.
- the pipe flange has a substantially circular passage cross-section, so that immediately adjacent a cylindrical pipe element can be mounted.
- the tubular element may be part of an exhaust pipe and / or a Exhaust gas purification unit (catalyst, filter or the like).
- the trough-shaped depression is sealingly closed towards the outside by means of the shell element 4, so that a volume of space results between the depression on the part of the cylinder head 1 and the shell element 4, in which several exhaust gas streams can be combined, diverted and forwarded to a downstream exhaust system.
- This volume of space is thus partly formed inside the cylinder head (side A) and partly outside the cylinder head (side B), resulting in a particularly simple and cost-realizable construction of two approximately vertically divided halves.
- constructive measures e.g. Dimensioning of the shape and depth of the shell element and the corresponding recess on the part of the cylinder head 1 set a desired heat transfer behavior.
- a heat input into the cooling water is reduced compared to a fully integrated into the cylinder head execution of Abgaskrummers, resulting in a faster heating downstream exhaust purification units.
