Hydrogen augmented diesel crankcase ventilation
First Claim
1. A hydrogen augmented crankcase ventilation system comprising:
- a diesel engine including;
an engine air intake;
an engine crankcase; and
the hydrogen augmented crankcase ventilation system comprising;
a hydrogen source;
a first hose connecting the hydrogen source to the engine air intake, the first hose carrying a first flow including hydrogen from the hydrogen source to the engine air intake;
a second hose connecting the engine crankcase to the engine air intake, the second hose carrying a second flow from the engine crankcase to the engine air intake, such that the first and second flows are combined together and joined with air received by the diesel engine through 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.

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.

18. A diesel cycle engine including a hydrogen augmented crankcase ventilation system, the engine comprising:
-
a diesel cycle engine including; an engine air intake residing between an air cleaner and a super charger; and an 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 hydrogen generator which generates hydrogen gas and oxygen gas; 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 engine air intake; a second hose connecting the 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, such that the first and second flows are combined together and joined with air received by the diesel cycle engine through 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. - View Dependent Claims (19)

20. A hydrogen augmented diesel cycle engine crankcase ventilation system comprising:
-
a diesel engine including an engine air intake residing between an air cleaner and a super charger; a hydrogen generator; 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 engine 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;
such that the first and second flows are combined together and joined with air received by the diesel engine through 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.
