Cylinder head for an internal combustion engine with an exhaust aftertreatment arrangement and an internal combustion engine with such a cylinder head
A cylinder head for an internal combustion engine with an exhaust aftertreatment arrangement includes a cylinder head base body, a valve cover connected to the cylinder head base body, and a carrier element for supporting the exhaust aftertreatment arrangement. The carrier element is supported against the cylinder head base body via a stud. The stud extends through the valve cover.
1 . A cylinder head for an internal combustion engine with an exhaust aftertreatment arrangement, comprising:
a cylinder head base body;
a valve cover connected to the cylinder head base body; and
a carrier element for supporting the exhaust aftertreatment arrangement,
wherein the carrier element is supported against the cylinder head base body via a stud,
wherein the stud extends through the valve cover.
2 . The cylinder head according to claim 1 , wherein the carrier element is connected to the stud on a first side of the valve cover and the stud is connected to the cylinder head base body on a second side of the valve cover opposite of the first side.
3 . The cylinder head according to claim 1 , wherein the valve cover has a through-hole through which the stud extends.
4 . The cylinder head according to claim 1 , wherein a sleeve is inserted into the valve cover, through which the stud extends.
5 . The cylinder head according to claim 4 , wherein the carrier element is connected to the stud on a first side of the valve cover and the stud is connected to the cylinder head base body on a second side of the valve cover opposite of the first side,
wherein a free end of the sleeve projects out of the valve cover on the first side of the valve cover.
6 . The cylinder head according to claim 4 , wherein the valve cover is made of a first material, and the sleeve is made of a second material, wherein the second material has a higher young's modulus than the first material.
7 . The cylinder head according to claim 1 , wherein the stud has a first threaded portion which is screwed into an internal thread in the cylinder head base body, and a first spacing portion which adjoins the first threaded portion and extends through the valve cover, and an abutment portion adjoining the first spacing portion.
8 . The cylinder head according to claim 7 , wherein the stud, the valve cover and the cylinder head base body are braced together, the abutment portion being supported on the valve cover.
9 . The cylinder head according to claim 7 , wherein a sleeve is inserted into the valve cover, through which the stud extends,
wherein the stud, the sleeve and the cylinder head base body are braced together, the abutment portion being supported on a free end of the sleeve.
10 . The cylinder head according to claim 7 , wherein the stud comprises a connecting portion which adjoins the abutment portion and to which the carrier element is connected.
11 . The cylinder head according to claim 10 , wherein the connecting portion comprises a second spacing portion which adjoins the abutment portion and extends through a through-hole of the carrier element, and a second threaded portion which adjoins the second spacing portion and is thus engaged with a nut, and the stud, the carrier element and the nut are braced together, the nut being supported on the carrier element and the carrier element being supported on the abutment portion of the stud.
12 . The cylinder head according to claim 1 , wherein the stud is a plurality of studs and the carrier element is supported on the cylinder head base body via the plurality of studs, the plurality of studs each extending through the valve cover.
13 . The cylinder head according to claim 12 , wherein the valve cover describes a central longitudinal plane which is arranged parallel to a longitudinal axis of the plurality of studs, and a first partial number of the plurality of studs is arranged on a first side of the central longitudinal plane and a second partial number of the plurality of studs is arranged on a second side of the central longitudinal plane.
14 . The cylinder head according to claim 13 , wherein studs of the first partial number of the plurality of studs and studs of the second partial number of the plurality of studs are arranged alternately in a longitudinal direction of the valve cover.
15 . An internal combustion engine including the cylinder head according to claim 1 .
