Abstract

A system, comprising, a combustion chamber, and a free-radical injector configured to inject free radicals into the combustion chamber at an ignition timing to trigger combustion of a fuel-air mixture.

Claims (25)

1. A system, comprising:

a combustion chamber; and

a free-radical injector configured to receive free radicals external from the free-radical injector and inject the free radicals into the combustion chamber at an ignition timing to trigger combustion of a fuel-air mixture.

2. The system of claim 1 , wherein the free-radical injector is configured to receive the free radicals from a combustion reaction in the combustion chamber.

3. The system of claim 1 , wherein the free-radical injector is configured to receive the free radicals from an external source separate from both the combustion chamber and the free-radical injector.

4. The system of claim 1 , wherein the free-radical injector comprises a positive displacement injector configured to force the free radicals into the combustion chamber at an ignition timing to trigger combustion of the fuel-air mixture.

5. The system of claim 4 , wherein the positive displacement injector comprises a rotary pump.

6. The system of claim 4 , wherein the positive displacement injector comprises a reciprocating pump.

7. The system of claim 4 , wherein the positive displacement injector comprises a fluid-driven drive.

8. The system of claim 4 , wherein the positive displacement injector comprises an electronic drive.

9. The system of claim 1 , comprising a pre-chamber coupled to the combustion chamber, wherein the free-radical injector is configured to inject the free radicals from the pre-chamber into the combustion chamber at the ignition timing to trigger combustion of the fuel-air mixture.

10. The system of claim 1 , wherein the free-radical injector excludes a spark ignition system.

11. The system of claim 1 , wherein the free radicals comprise peroxides, aldehydes, or a combination thereof.

12. A system, comprising:

a free-radical ignition controller configured to control a free-radical injector to receive free radicals external from the free-radical injector and inject the free radicals into a combustion chamber at an ignition timing to trigger combustion of a fuel-air mixture, wherein the free-radical injector is configured to receive the free radicals from an external source separate from both the combustion chamber and the free-radical injector.

13. The system of claim 12 , wherein the free-radical ignition controller is configured to control a positive displacement pump to force a flow of the free radicals from the free-radical injector into the combustion chamber.

14. The system of claim 12 , comprising the free-radical injector.

15. The system of claim 12 , wherein the free-radical injector is configured to receive a portion of the free radicals from a combustion reaction in the combustion chamber.

16. The system of claim 12 , wherein the free radicals comprise peroxides, aldehydes, or a combination thereof.

17. The system of claim 12 , comprising a combustion engine having the free-radical ignition controller.

18. A method, comprising:

receiving free radicals into a free-radical injector from an external source separate from both a combustion chamber and the free-radical injector; and

injecting the free radicals from the free-radical injector into the combustion chamber to trigger combustion of a fuel-air mixture.

19. The method of claim 18 , wherein receiving the free radicals comprises receiving the free radicals from a combustion reaction in the combustion chamber and the external source separate from.

20. The method of claim 18 , wherein injecting the free radicals comprises positively displacing the free radicals to force a flow of the free radicals from the free-radical injector into the combustion chamber.
