Embodiment Construction

[0035] Figure 1a The cylinder head 2 is shown with a spark plug sleeve 4 inserted into the cylinder head 2. The cavity 7 is formed by the spark plug sleeve 4 in this embodiment.

[0036] Figure 1b with 1c The spark plug sleeve 4 is shown in two views.

[0037] Figure 1a A longitudinal cross-sectional view of a cavity 7 is shown, which accommodates a spark plug 6 (not shown) and a pre-chamber valve 5.

[0038] On the one hand, the cavity 7 includes a concentric shaft around the axis of symmetry S1, which shaft includes a plurality of column sections and is used to accommodate the spark plug 6.

[0039] The cavity 7 furthermore has a hole with a symmetry axis S2 for receiving the pre-chamber valve 5.

[0040] The passage 8 leads from the pre-chamber valve 5 to the pre-chamber 3. The pre-chamber 3 includes on the one hand its own cavity, a so-called cavity, in which the ignition of the mixture takes place. Of course, the pre-chamber 3 is also a physical component. In this embodiment...

Abstract

The invention relates to a cylinder head (2) having a cavity (7) for accommodating a prechamber valve (5), wherein a The recess and the wall (10) of the cavity (7) surrounding the pre-chamber valve (5) form an annular channel (13), which is used to feed the pre-chamber valve (5) At least one gas supply channel (12) for supplying gas is connected, wherein the annular channel (13) is connected with the lower cavity (21) of the pre-combustion chamber valve (5) through at least one gas channel (20) arranged obliquely .

Description

Technical field [0001] The invention relates to a cylinder head with the features of the preamble of claim 1. Background technique [0002] The (gas) internal combustion engine is equipped with a pre-chamber for ignition amplification from a certain hole (about 150 mm). The ignition source extending into the pre-combustion chamber ignites the mixture that is relatively rich in grease in the cleaned pre-combustion chamber. As a result, the ignition tongue enters the main combustion chamber from the pre-combustion chamber and ignites the existing mixture. mixture. [0003] There are different designs for the fuel supply of the pre-chamber. In the unwashed pre-chamber, the mixture is compressed from the main combustion chamber into the pre-chamber during the compression stroke. [0004] In the cleaned prechamber, there is also the possibility of additionally supplying fuel to the prechamber. This separate fuel supply is achieved via the pre-chamber valve. The pre-chamber valve can ...
