1. Global software architecture

The file , on the modeling of combustion in automotive diesel engines, has shown that the data calculated by the thermodynamic model provides instantaneous curves for combustion temperature, cylinder pressure and wall heat flux. Similarly, the , on the modeling of the energy architecture of the engine itself, has shown that it is possible to describe in thermal detail the engine subjected to the controlled action of different cooling circuits. The thermodynamic combustion model and the engine thermal architecture model must then be coupled at combustion chamber wall level to model heat transfer from combustion gases generated by piston/ring/cylinder friction (cf. ).

In spite of the large heat flow amplitudes, the inertia and thickness of the chamber walls filter out these amplitudes. As a result, temperature...
