Abstract
In order to provide a method for operating a motor-vehicle engine adapted to be driven by hydrogen gas, wherein hydrogen gas is compressed to an operational pressure level required for the high-pressure injection, which also enables a hydrogen engine to be operated at a storage pressure of the hydrogen gas conveyed in the motor vehicle which is below the operational pressure level required for the high-pressure injection, it is suggested that the hydrogen gas at a pressure below the operational pressure level be cooled to cryogenic temperatures and that the cold gas be compressed by means of a compressor operating at cryogenic temperatures and heated up again in the compressed state.
