  • Internal combustion engine
    Patent number: 11970965
    Abstract: An internal combustion engine having a prechamber with first and second sub-chambers. The first sub-chamber has a prechamber gas valve and an igniter. The second sub-chamber has a plurality of first orifices to couple with a main combustion chamber. The second sub-chamber is coupled to the first sub-chamber via a direct connection or an indirection connection. The direct connection includes at least one second orifice, such as a plurality of second orifices. The indirect connection includes a third sub-chamber, wherein the third sub-chamber is coupled to the first sub-chamber by at least one third orifice (e.g., a plurality of third orifices), and the third sub-chamber is coupled to the second sub-chamber by at least one second orifice (e.g., a plurality of second orifices).
