Abstract: A method for absorbing hydrogen in a crankcase of a hydrogen internal combustion engine is provided, comprising injecting, by a hydrogen injector, hydrogen into a combustion chamber of the hydrogen combustion engine; wherein a piston of the hydrogen combustion engine is configured to compress and expand the hydrogen injected into the combustion chamber; injecting, by a nozzle, a hydrogen carrier medium into the crankcase for hydrogenation of the carrier medium inside the crankcase with hydrogen leaked from the combustion chamber past a side wall of the piston into the crankcase; collecting, by a collector, the hydrogenated carrier medium from the crankcase; heating, by a heater, the hydrogenated carrier medium for dehydrogenation of the carrier medium and extracting hydrogen from the hydrogenated carrier medium; and injecting, by the nozzle, the dehydrogenated carrier medium into the crankcase for hydrogenation. The present disclosure further provides a system for a motor vehicle, and a motor vehicle comprising the inventive system.

Abstract: Disclosed is a method for reducing friction in a radial drilling application. The method involves coating the interior of a deflector shoe with a lubricant. Lubrication of the deflector show can be accomplished by applying a wet lubricant to the interior of the deflector shoe or spraying a dry lubricant on the interior of the deflector shoe. The method can further include coating a hose and/or a jet nozzle, passing the hose and/or jet nozzle through the coated interior of the deflector shoe. The method can further include coating components of a milling cutter, and passing the components of the milling cutter through the coated interior of the deflector shoe. An apparatus for reducing friction in a radial drilling application is also disclosed.

Abstract: A powertrain system includes a housing that defines a reservoir. A shaft is rotatably disposed in the housing, and the shaft defines a bore. A cap is positioned to seal the reservoir. The cap defines an opening configured to supply lubricant to the shaft. The opening in the cap is positioned proximal the shaft to spray the lubricant into the bore. In one form, the cap has a nozzle, and the nozzle defines the opening configured to supply the lubricant to the shaft. The shaft is configured to rotate about a rotational axis, and the bore extends along the rotational axis of the shaft. The nozzle is aligned with the rotational axis of the shaft to spray the lubricant into the bore in order to lubricate bearings and other parts of the system.

Abstract: A quick return oil cylinder liner is disclosed. The cylinder liner includes an elongated cylindrical body having an outer surface and an inner surface defining a liner central axis extending between a first liner axial end and a second liner axial end. The inner surface is configured to form a combustion chamber with a piston and an engine housing. A quick oil return part is arranged on the inner surface of the cylinder liner corresponding to a non-skirt part of the piston. The oil return part is positioned below a position of the inner surface corresponding to an oil blade of an oil ring of the piston when the piston is positioned at a bottom dead center position. The oil return part extends to the second linear axial end and forms at opening at the second liner axial end.

Abstract: Provided is a method for preventing the accumulation of cylinder oil at scavenging ports of low-speed marine engines. An oil passage is provided on a cylinder wall inside a cylinder. The oil passage includes multiple oil storage grooves processed in a circumferential direction of the cylinder wall. The oil passage is formed by obliquely extending from the inner side of the cylinder wall to the outside of the cylinder in a radial direction of the cylinder. The scavenging ports are uniformly distributed in a circumferential direction of the cylinder wall, and each of the oil storage grooves is correspondingly processed at an upper portion of the scavenging port upper edge of the scavenging port. Each of the oil storage grooves has a shape matching the curved surface of the scavenging port upper edge.
