1.1 Different modeling approaches

To better understand the impact of thermal parameters on the fuel consumption and cabin heating performance of an automotive internal combustion engine, we need a numerical simulation tool. This tool for analyzing transient thermal phenomena has two functions. The first is to enable a precise study of sensitivity to cooling function control parameters, as highlighted in the dossier. , on energy exchanges and thermal balances within the engine. Its second function is to support the development of control and regulation strategies associated with the cooling system.
