Abstract

A hydrogen augmented diesel crankcase ventilation system uses hydrogen to allow crankcase fumes, for example blow-by, to be burned by the engine. The system preferably includes a hydrogen generation system as a hydrogen source connected to an engine air intake by a first hose, a second hose connecting the crankcase to the air intake, and a third hose connecting a fresh air source to the crankcase. An orifice or a vacuum regulator in cooperation with the second hose may be included to regulate crankcase vacuum. A filter may reside inline with the second hose to capture solids or liquids which enter the second hose from the crankcase. A back flow preventor may be included in cooperation with the third hose to prevent a back flow of crankcase fumes through the third hose.

Claims

1. A hydrogen augmented crankcase ventilation system comprising:

a hydrogen source;

a first hose connecting the hydrogen source to an engine air intake, the first hose carrying a first flow including hydrogen from the hydrogen source to the air inlet;

a second hose connecting an engine crankcase to the engine air intake, the second hose carrying a second flow from the crankcase to the engine air intake; and

a third hose in fluid communication with the engine crankcase, the third hose carrying a third flow of fresh air.

2. The system of claim 1, wherein the hydrogen source is a hydrogen generator and the first hose carries hydrogen gas to the air intake.

3. The system of claim 2, wherein the first hose carries both hydrogen gas and oxygen gas to the air intake.

4. The system of claim 1, wherein the engine air intake resides between an air cleaner and a super charger.

5. The system of claim 4, wherein the engine air intake resides between an air cleaner and a turbo charger.

6. The system of claim 1, wherein the third hose is connected between a second air cleaner and the crankcase.

7. The system of claim 6, wherein the second air filter includes an in-line back flow preventor.

8. The system of claim 6, wherein the third hose includes an in-line back flow preventor.

9. The system of claim 1, wherein the third hose connects to the crankcase through an oil fill tube.

10. The system of claim 1, wherein the second hose includes an inline filter for collecting liquids which enter the second hose.

11. The system of claim 1, wherein the in-line filter includes a clear portion for viewing liquids collected by the in-line filter.

12. The system of claim 1, wherein the second flow is restricted to limit the amount of flow.

13. The system of claim 12, wherein the second flow is restricted to result in a crankcase vacuum between approximately one pound and approximately four pounds.

14. The system of claim 1, further including an orifice for regulating the second flow through the second hose from the crankcase to the air intake.

15. The system of claim 14, wherein the orifice resides proximal to where the second hose connects to the air intake.

16. The system of claim 1, wherein the first hose and the second hose connect to the engine air intake at spaced apart points.

17. The system of claim 1, wherein the third hose includes a vacuum regulator.

18. A diesel cycle engine including a hydrogen augmented crankcase ventilation system, the engine comprising:

a hydrogen generator which generates hydrogen gas and oxygen gas;

an engine air intake residing between an air cleaner and a super charger;

a first hose connecting the hydrogen generator to the engine air intake which first hose carries a first flow from the hydrogen generator to the air intake;

a diesel cycle engine crankcase containing at least one of a set of crankcase fumes consisting of blow-by and fumes resulting from the breakdown of engine oil;

a second hose connecting the diesel cycle engine crankcase to the engine air intake, which second hose carries a second flow of crankcase fumes from the crankcase to the engine air intake;

a third hose connecting a second air cleaner to the engine crankcase to provide a third flow of fresh air to the crankcase; and

a restriction cooperating with the second flow.

19. The system of claim 18, wherein the third hose includes a vacuum regulator.

20. A hydrogen augmented diesel cycle engine crankcase ventilation system comprising:

a hydrogen generator;

an engine air intake residing between an air cleaner and a turbo charger.

a first hose connecting the hydrogen generator to the engine air intake, which first hose carries hydrogen gas and oxygen gas generated in the hydrogen generator to the air intake;

a second hose connecting an engine crankcase to the engine air intake to carry a second flow of crankcase fumes from the engine crankcase to the engine air intake;

a restriction cooperating with the second flow to restrict the second flow;

a third hose connecting a fresh air source to the engine crankcase to carry fresh air to the engine crankcase; and

a back flow preventor cooperating with the third hose to prevent a back flow through the third hose.
