    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 is provided for starting an internal combustion engine which includes a starter, an ignition, pressure store and injection valves for injecting fuel directly into the engine. An electrical high pressure pump is connected to an electrical fuel pump downstream thereof for pumping the fuel into the pressure store. The electrical fuel pump and the electrical high pressure pump are first switched on together with the ignition in order to generate a pressure in the pressure store adequate for the injection of the fuel. Then, the starter is switched on after a time duration after the electric fuel pump and the electrical high pressure fuel pump are switched on.

    摘要: An internal combustion engine for a motor vehicle in particular is described, provided with an injection valve for injecting fuel directly into a combustion chamber either during an intake phase in a first operating mode or during a compression phase in a second operating mode. In addition, a control unit is also provided for controlling and/or regulating a fuel mass injected into the combustion chamber differently in the two operating modes. The control unit is designed so that a required air mass can be determined from a torque demand in the first operating mode, and then the fuel mass to be injected can be determined from the required air mass, and in the second operating mode the fuel mass injected can be determined directly from the torque demand.

    摘要: A fuel supply system (1) for an internal combustion engine, especially of a motor vehicle, is described which is provided with an accumulator (2) and a pump (6, 10). Fuel can be supplied to the accumulator (2) with the pump (6, 10). A control apparatus (16) is provided for controlling (open loop and/or closed loop) the pressure in the accumulator (2) by a pressure control valve (4). With the control apparatus (16), the pressure control valve (4) can be closed when the engine is intended to be started but no rotational movement is yet present.

    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 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.
