Embodiment Construction

[0032] The invention is explained below with reference to the example of a partial region of a cylinder head. Figure 1 to Figure 4 A starting model of a partial region of the cylinder head, ie the region above the combustion chamber of the cylinder, is shown schematically in a perspective view. figure 2 A first variant of a partial region of a cylinder head designed according to the invention is shown schematically in a perspective view. image 3 A second variant of a partial region of the cylinder head according to the invention is shown schematically in a perspective view. Figure 4 A third variant of a partial region of the cylinder head according to the invention is shown schematically in a perspective view.

[0033] figure 1 The illustrated subregion of the cylinder head 1 is designed for an internal combustion engine, for example a gasoline-operated internal combustion engine. The cylinder head 1 comprises a combustion chamber side wall 2 , in particular in the regi...

Abstract

The invention relates to combustion chamber cooling for an internal combustion engine. A combustion chamber component (20, 30, 40) configured to have double walls and used for an internal combustion engine (50) is described, wherein the combustion chamber component comprises a combustion chamber side wall (2) with a combustion chamber side surface (5) and an inner surface (6) and an outer wall (3)with an inner surface (7) and an outer surface (8). In this case, at least one flow channel (9, 21) is arranged between the combustion chamber side wall (2) and the outer wall (3). The combustion chamber side wall (2) has a thickness (4) of less than 6 mm.

Description

technical field [0001] The invention relates to components for combustion chambers of internal combustion engines, in particular for cylinder heads. The invention also relates to an internal combustion engine, a vehicle, and a method for manufacturing components for combustion chambers, in particular for cylinder heads. Background technique [0002] Ideal and efficient combustion in internal combustion engines is only possible in a limited manner in the case of high-load and full-load operation, knocking which often occurs due to undesired pre-ignition. This relates in particular to gasoline-operated engines. Typically, using a knock sensor, the knock that occurs in the engine is detected and the ignition timing is shifted to less efficient crank angles. As a result, there is then less knocking or no knocking at all, but increased fuel consumption. Therefore, an engine with less knock cannot be operated in an efficient manner or at a higher power level. [0003] To preve...
