The invention relates to a test apparatus for checking a battery control device or for checking a battery having at least one cell, comprising a battery simulator () for simulating a voltage of at least one cell of a simulated battery for specification on the battery control device, wherein the battery control device or the battery is connected to an evaluation module () via a rail designed as a central bus in order to process and check the voltage of a selected cell, wherein the selected cell of the battery simulator for the battery control device or the selected cell of the battery can be selected via a separation module (). In this way, a test apparatus for checking a battery control device or for checking a battery can be provided, which has a simple construction and can check all of the cells of a simulated or actual battery in a simple manner.

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.

Afterburner device and method for operating an afterburner device

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.

Fuel-injection system and method for injecting fuel

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.

Fuel injector nozzle seal

In a fuel supply system for an internal combustion engine in which a gas delivery pump, a fuel pump and an electric motor are included in the fuel supply system and form a pump unit, the electric motor is incorporated in the system in such a way that it can selectively drive either one or both of the pumps.

Fuel supply system including a pump unit

In a fuel supply system for an internal combustion engine having two separate storage containers for liquid fuels, both connected to a first controllable valve which is connected, via a connecting line including a fuel pump to an inlet of a second controllable valve having two outlets in communication by separate fuel lines with a fuel injection nozzle of the internal combustion engine, each of the two separate fuel lines includes a fuel pressure regulator, one being in communication with one and the other with the other of the two separate fuel storage containers for returning exess fuel to the fuel storage container from which fuel is being supplied to the fuel injection nozzle.

Fuel supply system for an internal combustion engine

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.
