Abstract: An afterburner device and a method for operating an afterburner device, especially for chemical reformers for obtaining hydrogen, for making heat available from fuels and/or residual gases from a reforming process and/or a fuel cell process. In this context, heat is supplied in a controlled manner from recirculated combustion gases to a first housing and/or a combustion chamber situated in it and at least in part filled with heat resistant, open-pored foamed ceramics. The regulation takes place, for instance, based on a temperature recorded in the combustion chamber using an infrared light measurement.

Abstract: A fuel-injection system for injection of fuel into an internal combustion engine includes at least one fuel injector and a first fuel-distributor line which is connected to the at least one fuel injector. A second fuel-distributor line is provided which is connected to the at least one fuel injector via an individual corresponding lance.

Abstract: A fuel injector for the direct injection of fuel into the combustion chamber of a mixture-compressing internal combustion engine having external ignition includes a valve housing formed by a nozzle body, and a seal which seals the fuel injector from a cylinder head of the internal combustion engine. The seal has a sleeve-type design with a structured cross section and extends across the axial length of the nozzle body.

Abstract: The fuel cell apparatus includes a fuel cell (3) for converting chemical energy into electrical energy by burning a hydrogen-enriched liquid (7), a fuel-converting unit (22) for converting hydrocarbon-containing substances (11,12) to the hydrogen-enriched fluid (7), a first tank (1) for storing a first hydrocarbon-containing mixture (11) and optionally an internal combustion engine (4) which burns the hydrocarbon-containing substance. The production of the hydrogen-enriched fluid (7) is improved, especially in the cold starting operation stage, when the fuel cell apparatus includes a device for supplying a second hydrocarbon-containing mixture (12) at least to the fuel-converting unit (22) in certain operating stages.

Abstract: A method and a device for driving at least one solenoid valve used for controlling the injection of fuel into an internal combustion engine. At the start of the driving (activation), the solenoid valve is supplied with a booster voltage that is elevated as compared to that used for the further driving. The energy and/or power output received by the solenoid valve at the start of the driving is able to be influenced as a function of the operating state of the internal combustion engine.
