Hydrogen Supply System for an Internal Combustion Engine

Abstract

A hydrogen supply system for an internal combustion engine includes an inlet-side high-pressure region, an outlet-side low-pressure region and a medium-pressure region which is arranged fluidically between the high-pressure region and the low-pressure region. A mechanical pressure-reducing device is provided to lower a high pressure in the high-pressure region to a medium pressure in the medium-pressure region. An electrically actuable pressure-reducing device is provided to lower the medium pressure in the medium-pressure region to a low pressure in the low-pressure region. A pressure-limiting valve and, downstream of the latter, a shut-off valve are arranged in the middle-pressure region and/or in the low-pressure region. The hydrogen supply system can include, in particular, a single hydrogen supply unit (“one-box solution”).
