Gas valve for an internal combustion engine

A system, comprising:

• a pre-chamber gas valve, comprising:
• a valve housing having a valve seat and at least one gas channel;
• and
• a valve body having at least one recess, wherein the valve body is configured to move along a longitudinal axis in the valve housing to open and close against the valve seat, wherein the valve body is configured to move an axial distance between a seated position of the valve body against the valve seat and a lifted position of the valve body lifted away from the valve seat, wherein the at least one recess is configured to provide a fluid connection between the at least one gas channel and a pre-chamber after the valve body moves away from the seated position, wherein the at least one recess is configured to block the fluid connection between the at least one gas channel and the pre-chamber in the lifted position of the valve body.

A method, comprising:

• operating a pre-chamber gas valve of a pre-chamber assembly of an internal combustion engine, comprising:
• moving a valve body along a longitudinal axis in a valve housing to open and close against the valve seat, wherein the valve body is configured to move an axial distance between a seated position of the valve body against the valve seat and a lifted position of the valve body lifted away from the valve seat;
• opening a fluid connection between at least one recess in the valve body, at least one gas channel in the valve housing, and a pre-chamber after the valve body moves away from the seated position;
• and
• blocking the fluid connection between the at least one recess in the valve body, the at least one gas channel in the valve housing, and the pre-chamber in the lifted position of the valve body.
