Abstract
Air is cooled to conditions where the oxygen component of the air is liquid and the nitrogen component of the air is gaseous using fuel for an engine as a heat sink. The oxygen is separated from the nitrogen, and the oxygen is supplied to the engine for combustion.
Claims21
A method, comprising:
- cooling air to conditions where the oxygen component of the air is liquid and the nitrogen component of the air is gaseous using the fuel for a single fuel engine as a heat sink;
- separating the oxygen from the nitrogen;
- supplying the oxygen to the engine for combustion by feeding the oxygen directly into a prechamber igniter of the engine;
- and
- supplying the entire charge of the fuel to the engine for combustion by feeding the fuel directly into the prechamber igniter of the engine.

2-3. (canceled)
A system, comprising:
- a heat exchanger configured to receive air and the fuel for a single fuel engine and cool the air, using the fuel as a heat sink, to conditions where the nitrogen component of the air is gaseous and the oxygen component of the air is liquid;
- an exhaust coupled to the heat exchanger to exhaust the nitrogen component;
- a supply coupled to the heat exchanger to supply the oxygen to a combustion chamber of the engine, where the supply supplies the oxygen directly into a prechamber igniter in the combustion chamber of the engine;
- and
- a fuel supply to supply the entire charge of the fuel directly into the prechamber igniter.

A method, comprising:
- separating oxygen and nitrogen from air by cooling the air using the fuel for a single fuel engine as a heat sink;
- and
- supplying the oxygen and the entire charge of the fuel to the engine to an interior of a prechamber igniter for combustion.
