Abstract
Cylinder head assembly for an internal combustion engine, comprising: a cylinder head having a flame deck at least partially provided for covering a main combustion chamber and a cavity for receiving a pre-chamber component, a pre-chamber component arranged inside the cavity facing the flame deck, wherein the pre-chamber component comprises a pre-chamber, wherein the pre-chamber component comprises a first sealing surface which is in contact with and preloaded against a corresponding second sealing surface of the cylinder head sealing the cavity of the cylinder head.
Claims20
A system, comprising:
- a cylinder head assembly of an internal combustion engine, wherein the cylinder head assembly comprises:
- a cylinder head having a flame deck at least partially provided for covering a main combustion chamber and a cavity for receiving a pre-chamber component;
- and
- a pre-chamber component arranged inside the cavity facing the flame deck, wherein the pre-chamber component comprises a pre-chamber, the pre-chamber component comprises a first sealing surface which is in contact with and preloaded against a corresponding second sealing surface of the cylinder head sealing the cavity of the cylinder head.
A system, comprising:
- a pre-chamber component of an internal combustion engine, wherein the pre-chamber component comprises:
- a first pre-chamber portion having a pre-chamber;
- and
- a second pre-chamber portion having one or more openings coupled to respective transfer passages in fluid communication with the pre-chamber, wherein the one or more openings are disposed on a tip portion, the second pre-chamber portion comprises a second material having a lower thermal conductivity than a first material of the first pre-chamber portion.
A method, comprising:
- forming a pre-chamber component of an internal combustion engine with first and second pre-chamber portions, wherein the first pre-chamber portion comprises a pre-chamber, the second pre-chamber portion comprises one or more openings coupled to respective transfer passages in fluid communication with the pre-chamber, the one or more openings are disposed on a tip portion, and the second pre-chamber portion comprises a second material having a lower thermal conductivity than a first material of the first pre-chamber portion.
