Embodiment Construction

[0027] figure 1 and figure 2 A corresponding illustration of a cylinder head 10 of a turbocharged internal combustion engine 1 (not completely shown) according to an embodiment of the invention is shown. The internal combustion engine 1 is designed as a large diesel engine, such as is used, for example, in marine applications and power station applications (eg power station applications).

[0028] The internal combustion engine 1 is equipped with an exhaust gas recirculation system (not shown) as described here in its basic function, for example in DE 4231 218 C1 or in DE 10 2005 017 905 A1.

[0029] The cylinder head 10 is made of an inexpensive but corrosive casting material, preferably EN-GJS-400-15 (GGG-40).

[0030] The cylinder head 10 of the internal combustion engine 1 has a plurality of medium channels (identified only one medium channel 11 ) each having a medium contact surface provided for conducting the medium.

[0031] According to the invention, the medium co...

Abstract

The invention relates to a cylinder head (10) and to an internal combustion engine (1) equipped therewith, wherein the cylinder head has a plurality of media passages, each of which has a media contact surface for conducting a medium. The cylinder head is designed in such a way that the cylinder head has an increased service life compared to the prior art. This is achieved, inter alia, in that the media contact surface (11a) of at least one media passage (11) for conducting a corrosive medium of the plurality of media passages is made of corrosion-resistant material.

Description

technical field [0001] The invention relates to a cylinder head according to the preamble of claim 1 and to an internal combustion engine equipped with such a cylinder head. Background technique [0002] A cylinder head of the type mentioned at the outset is known, for example, from DE 689 27 359 T2. Due to the media flowing through the cylinder head, such cylinder heads are subject to constant wear, which adversely affects the service life of the cylinder head. Contents of the invention [0003] The object of the invention is to provide a cylinder head according to the preamble of claim 1 which has an increased service life. A further object of the invention is to provide an internal combustion engine equipped with such a cylinder head. [0004] The above objects are achieved with a cylinder head according to claim 1 or with an internal combustion engine according to claim 9 . Developments of the cylinder head according to the invention are defined in the dependent cla...
