An embodiment hydrogen direct injection system for an internal combustion engine of a motor vehicle includes a fuel line and a fuel injector configured to inject hydrogen fuel into a combustion chamber of the internal combustion engine, wherein the fuel injector is configured to receive the hydrogen fuel via the fuel line and to receive water via the fuel line, and wherein the water is configured to lubricate the fuel injector.

Hydrogen direct injection system and method for lubricating a fuel injector of a hydrogen direct injection system

An embodiment system for lubricating a hydrogen injector in a vehicle includes an extraction and separation device configured to collect at least a fraction of an exhaust gas of a hydrogen combustion engine and separate a water component from the collected fraction of the exhaust gas to provide liquid water and dried exhaust gas and a reactor connected to the extraction and separation device and configured to generate nitric acid from the liquid water and a nitrogen oxide content of the dried exhaust gas, wherein the hydrogen injector is connected to the reactor and configured to receive the generated nitric acid for lubrication.

System, vehicle and method for lubricating a hydrogen injector in a vehicle

An electronic control unit for a vehicle with a combustion engine and a method of fuel analysis are provided. At least one dynamic torque sensor value from a high pressure pump of the vehicle and at least one additional sensor value including at least one pressure sensor value and/or at least one timing value are used to determine whether a combustible fuel type currently in use is known, unknown, or similar to a known fuel type. In each case, the operation of the combustion engine is optimized using specific parameter configurations for the fuel injectors of the vehicle. The specific parameter configurations are either retrieved from a database, or are generated using artificial intelligence methods.
