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 hydrogen hose, a fumes hose connecting the crankcase to the air intake, and a clean air hose connecting a clean air source to the crankcase. An orifice or a vacuum regulator in cooperation with the fumes hose may be included to regulate crankcase vacuum. A filter resides inline with the fumes hose to capture solids or liquids which enter the fumes hose from the crankcase, and a drain hose drains captured liquid back into the engine. A back flow preventor may be included in cooperation with the clean air hose to prevent a back flow of crankcase fumes through the clean air hose.
