    摘要： A pump has a shaft, an impeller arranged on the shaft, and a labyrinth seal which is arranged between stationary and moving parts of the pump. A plurality of blades are arranged on the rotor and a labyrinth seal extends at least between the shaft and a rear portion of the blades. A gap in the labyrinth seal is designed such that liquid water can be actively carried away, with the labyrinth seal for this purpose being designed at least in places with a channel in the form of a spiral and/or a staircase. The invention also relates to a fuel cell system having such a pump.

    摘要： A method for simulating control functions of a control device, in which a control program code for execution of control functions is stored in a first memory area of a memory belonging to the control device, the control program code including one or more control program code modules for the control functions, and containing at least one switching device for switching over from a control program code module SPCM to a simulation program code module. At least one simulation program code module for one or more test control functions is made available in a second memory area of the memory. The switching devices switch over from the control program code module to a pertinent simulation program code module stored in the second memory area. The control program code is then processed, the simulation program code module being executed, via the switched-over switching device, instead of the control program code module.

    摘要： A method for determining the load angle of a three-phase current synchronous machine with the aid of position information of an internal combustion engine. The latter is furnished with an engine control device, in which operating parameters and the position information of components of the internal combustion engine are stored. The following method steps are run through: First of all, the rotational position of the internal combustion engine is recorded in the engine control device when the internal combustion engine is switched off. Before the start of the internal combustion engine, the transmission of the rotational position information of the internal combustion engine to the electrical three-phase current machine takes place for the adjustment between the rotational position information and the load angle of the electrical three-phase current machine, at a rotational speed of the internal combustion engine of n=0.

    摘要： The invention is based on a method for detecting slip in the driving of generator or starter-generator systems. The alternators of these systems are equipped with electronic control components such as pulse-width-modulated inverters or rectifier bridges. The drive torque of the alternator is transferred to this by means of a belt drive of an internal combustion engine. When slip is detected in a comparison step (3), to which speed-dependent input variables (1, 2) are forwarded, the maximum transferrable drive torque is determined in a torque limiting step (18, 20), and a closed-loop control (23) adjusts the generator output power to said maximum transferrable drive torque.

    摘要： A method is provided for starting an internal combustion engine for a motor vehicle, and an internal combustion engine is provided which employs such method. The internal combustion engine includes a piston which can move in a cylinder and can execute an intake stroke, a compression stroke, a power stroke and an exhaust stroke. In addition, a control unit is provided with which fuel can be injected directly into a combustion chamber, which is delimited by the cylinder and the piston either during a compression stroke in a first operating mode or during an intake stroke in a second operating mode. The control unit is designed so that for starting, fuel can be injected in a first injection directly into the combustion chamber whose respective piston is in the power stroke.
