Abstract
An engine is provided. In one embodiment, the engine includes a precombustion chamber having a body, a secondary combustion chamber disposed at least partially in the body, and a plurality of passages configured to place the precombustion chamber in fluid communication with a main combustion chamber.
Claims25
A system, comprising:
- an engine, comprising:
- a cylinder;
- a head having an inner wall with a first dome-shaped portion recessed into the head;
- a piston disposed in the cylinder, wherein a first combustion chamber is disposed between the head and the piston, wherein the piston is configured to reciprocate along a central axis of the cylinder;
- and
- a second combustion chamber centered relative to the central axis of the cylinder, wherein the second combustion chamber comprises a body having an interior volume centered relative to the central axis, an outlet passage fluidly coupling the interior volume with the first combustion chamber, and an ignition device configured to ignite a fuel to generate a flame,
- wherein the outlet passage comprises a first outlet passage that directly intersects with a curved portion of the second combustion chamber, wherein the first outlet passage is angled greater than or equal to 155 degrees relative to the curved portion of the second combustion chamber,
- wherein the first outlet passage is nonparallel with the central axis,
- wherein the body has a second dome-shaped portion protruding from the first dome-shaped portion of the head into the first combustion chamber,
- wherein the first dome-shaped portion has a first curvature that is symmetrical about the central axis, and the second dome-shaped portion has a second curvature that is symmetrical about the central axis.

A system, comprising:
- a second combustion chamber configured to couple to a first combustion chamber having a piston disposed in a cylinder and configured to reciprocate along a central axis of the cylinder, wherein the second combustion chamber comprises:
- a body having an interior wall surrounding an interior volume centered relative to the central axis and an end surface configured to face the first combustion chamber, wherein the end surface comprises a dome-shaped portion having a curved surface that is symmetrical about the central axis;
- an outlet passage configured to fluidly couple the interior volume with the first combustion chamber, wherein the outlet passage comprises a first outlet passage that extends away from the interior wall of the interior volume in a first direction acutely angled towards the central axis, the first outlet passage directly intersects with a curved portion of the interior wall of the interior volume, the first outlet passage is nonparallel with the central axis, the first outlet passage is angled greater than or equal to 155 degrees relative to the curved portion of the interior wall of the interior volume, the outlet passage comprises a plurality of second outlet passages coupled to and diverging away from the first outlet passage toward the end surface of the body, each second outlet passage of the plurality of second outlet passages are is acutely angled away from the central axis;
- and
- an ignition device configured to ignite a fuel to generate a flame.
2 more elements
A system, comprising:
- a second combustion chamber configured to couple to a first combustion chamber having a piston disposed in a cylinder and configured to reciprocate along a central axis of the cylinder, wherein the second combustion chamber comprises:
- a body having an interior wall that curves around at least a substantial portion of an interior volume that is centered relative to the central axis;
- a fuel inlet passage fluidly coupled to the interior volume, wherein the fuel inlet passage directly intersects with a first curved portion of the interior wall of the interior volume, the fuel inlet passage is nonparallel with the central axis, and the fuel inlet passage is angled greater than or equal to 155 degrees relative to the first curved portion of the interior wall of the interior volume;
- an outlet passage fluidly coupled to the interior volume separate from the fuel inlet passage, wherein the outlet passage directly intersects with a second curved portion of the interior wall of the interior volume, the outlet passage is nonparallel with the central axis, the outlet passage is angled greater than or equal to 155 degrees relative to the second curved portion of the interior wall of the interior volume, and the outlet passage is configured to fluidly couple the interior volume with the first combustion chamber;
- and
- an ignition device configured to ignite a fuel to generate a flame, wherein the ignition device is centered relative to the central axis.
