Abstract: A hyperbaric fuel system (10a, 10b) produces hydrogenated liquid fuel (30) for combustion reactions of compression or spark ignition engines and improves fossil fuel efficiency without requiring major changes to existing fuel systems. The hydrogenated liquid fuel (30) decreases the NOx, CO and unburned hydrocarbon particulate matter, and reduces the consumption of liquid fuel (26). The systems produces hydrogen gas (18) and dissolves the hydrogen gas (18) in the liquid fuel (26) using several chambers, including a hyperbaric mixing chamber (58), between the liquid fuel supply and a fuel pump (28) supplying the hydrogenated liquid fuel (30) to fuel injectors (40). Unused hydrogen gas (18) and hydrogenated liquid fuel (30) is recirculated to minimize loss of efficiency. The system preferably includes a water reservoir and electrolysis device to generate the hydrogen gas.

Abstract: A hydrogen augmented crankcase ventilation system includes hydrogen injection to facilitate the combustion of crankcase fumes, for example blow-by, in the engine. The system preferably includes a hydrogen generation system as a hydrogen source and introduces the hydrogen into the engine through the engine's fuel injection system. A fumes hose connects the crankcase to the air intake, and a clean air hose connects a clean air source to the crankcase. An orifice or a vacuum regulator cooperates with the fumes hose and 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 to cooperate with the clean air hose to prevent a back flow of crankcase fumes through the clean air hose.
