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.
