One-Dimensional Simulation (1D-CFD-Simulation)
The 1D-CFD-simulation can be seen as an extension of the cylinder real working-process analysis. The latter provides mainly the calculation of the working period of each cylinder (i.e. when the valves are closed) while the 1D-CFD-simulation analyzes the flow field in the whole intake and exhaust track, respectively. This approach can ensure an accurate calculation of the engine exchange-process, so that e.g. reliable initial conditions for the real working-process analysis at intake valve close (IVC) can be provided.
