Tool-based layout and optimisation of cylinder head’s gas exchange
Among other aspects, the development of combustion processes focuses on demands relating to cylinder charge and charge motion. The geometry of the intake port has a decisive impact in this regard.
The aim is to achieve the optimum combination (as the best compromise) of characteristic gas exchange parameters required on the combustion process side under predefined package conditions. This makes it essential to know or determine the optimum (Pareto front) as well as the associated port geometries.
This paper demonstrates how a combination of CAD model, CFD simulation and a mathematical substitute model can be used to identify the best possible compromise in terms of gas exchange parameters.
