    In the development of new internal combustion engines, the use of realm-m-mhmatmullin semidnostrelles plays an increasingly important role. By means of such an organism, it is already possible to: In; In a very early phase of moors development, individual concepts of the vehicle can be evaluated effectively, for example, that the development time and number of radiotransponders can be significantly reduced. The use of motor test equipment is also essential in the development of internal combustion engines, since here, in particular in the Elnzyilider test kits, for example, individual components with combustion components can be exhausted with reduced expenditure; and extensive adjustment possibilities for combustion amoloric operating variables such as air mass flow or Ahgasuckuhrmnmrsi® covered Äcl. In order to further combine the models of engine models and aerodynamic test rigs: to further optimize vibration control, it is also known to mop up a mofOAPrOfstand with a yotar-Blmulaflensniodell: to hopp > AUS: the DE 1ÖP; For example, 2Q 448 AI goes through a procedure; for optimizing the operation of an internal combustion engine, in which: a VöllmotoeProBtanO: wm. A phosphorus anode is coupled in order to describe a functional relationship between boiling characteristics and target variables of the internal combustion engine. This should; For each operating point of the connection motors, a database is created, which enables the use of the manipulated variables as a function of the magnitudes without further use. The optimization is thereby carried out exclusively by means of a computer, whereby the optimized steep variables are particularly favorable; can be determined quickly. These! However, HacMeil has the method that the functional relationship between the steep and the difficult or insufficiently accurate can be determined. In addition, isles on a presence of mehrzylmdrigen Vollmotors instructed.
    It is the object of the invention to provide a method for simulating the operation of an internal combustion engine and a device for carrying out the method by means of which the operation of the magnetic field can be simulated in a simple way, or particularly suitably.
