This study deals with the development of a numerical tool developed to analyze the thermo-management of the heat rejection from the fuel combustion in the case of a four cylinder 2 L - 110 HP direct injection Diesel engine. It is composed of two main elements: the first one simulates all the phenomena linked to the combustion, the second one is about thermal exchanges in the heart of the engine. We only deal with the first one here.
