Abstract
Methods and systems are provided for a cylinder head. In one example, a system comprises cylinder head having a bore arranged therein. The bore comprises a coupling element therein configured to selectively receive an ignition plug.
Claims18
A system, comprising:
- a cylinder head coupled to a combustion chamber, the cylinder head comprising a bore, wherein the bore comprises an upper portion configured to selectively receive an ignition plug and a lower portion into which an electrode of the ignition plug extends, and the system being an engine system,
- wherein the lower portion of the bore is a prechamber of the cylinder head that is outside of the combustion chamber and separated from the combustion chamber via a base, wherein the base is positioned completely above the combustion chamber,
- wherein the base is positioned between the cylinder head and the combustion chamber, wherein the upper portion and the lower portion are completely external to a top wall of the combustion chamber,
- wherein a piston is positioned within the combustion chamber,
- wherein the base is above the combustion chamber and directly on top of the combustion chamber,
- wherein the base comprises a plurality of apertures configured to fluidly couple the lower portion of the bore to the combustion chamber, and
- wherein the base is externally accessible and forms part of an external surface of the engine system.
4 more elements
An engine system, comprising:
- a combustion chamber shaped via a cylinder block and a cylinder head, wherein a piston is configured to oscillate within the combustion chamber along an axis;
- and
- a bore arranged in the cylinder head fluidly coupled to the combustion chamber via a plurality of apertures arranged in a base of the cylinder head,
- wherein the base spatially separates a prechamber that is in a lower portion of the bore from the combustion chamber,
- wherein the bore further comprises a threaded portion that is in an upper portion of the bore and configured to receive an ignition plug,
- wherein an electrode of the ignition plug is positioned within the prechamber,
- wherein the prechamber and the electrode of the ignition plug are positioned outside of the combustion chamber,
- wherein the base is outside of the combustion chamber, the base positioned between the cylinder head and the combustion chamber,
- wherein the base is above the combustion chamber and directly on top of a top wall of the combustion chamber, and
- wherein the upper portion and the lower portion are completely external to a top wall of the combustion chamber, and
- wherein the base is externally accessible and forms part of an external surface of the engine system.

- wherein the base spatially separates a prechamber of the bore from the combustion chamber,
- wherein the bore further comprises a threaded portion that is in an upper portion of the bore configured to receive an ignition plug,
- wherein the threaded portion allows a negative electrode of the ignition plug to extend into the prechamber that is in a lower portion of the bore,
- wherein the negative electrode of the ignition plug and the prechamber are positioned outside of the combustion chamber and separated from the combustion chamber, and
- wherein the base is outside and completely above the combustion chamber, the base positioned between the cylinder head and the combustion chamber,
- wherein the base is positioned above the combustion chamber and directly on top of the combustion chamber,
- wherein the upper portion and the lower portion are completely external to a top wall of the combustion chamber, and
- wherein the base is externally accessible and forms part of an external surface of the engine system.
