To reduce the time of the development loop for these concepts, 1D approaches can be used to simulate whole-engine behaviour. These approaches are based on phenomenological models that need to be fitted to experimental data. However these data are not always available. One way to solve this problem consists in combining 1D and 3D approaches: 1D simulations are used in the gas exchange system or for the fuel injection system and provide necessary inputs (e.g. volumetric efficiency, thermodynamic state, mixture composition, mass flow rate, etc.) for 3D simulations which are used in the combustion chamber to ensure an accurate description of the combustion process (especially pollutant emissions). This strategy allows us to obtain much more information and should improve the predictivity of the simulation. Two different approaches to carry out this coupling have been developed, the first one is based on the pre-processing of the 3D numerical results to generate combustion maps and the second one used a direct temporal coupling between the 1D and the 3D codes. The two methods are described in this paper. We also report on the relevant engine simulations which were carried out to demonstrate the capabilities of the two coupled approaches.
