The resonance due to the oscillation of burned gases in the combustion chamber is particularly important in DI diesel engines. This effect can be an important excitation source of the engine block during the combustion process.Experimental studies have many limitations. Among them, the difficulty of placing different pressure transducers in the combustion chamber and the high cost of operating and mounting in an experimental room, are the most relevant. Therefore additional methodologies can be of interest.In this paper a computational fluid dynamics (CFD) approach for the study of DI automotive Diesel engine resonance is presented. With this methodology it is possible to simulate the resonance phenomenon due to the auto-ignition and the combustion process by means of energy sources. During the calculation the pressure evolution is registered in different points of the domain, and this provides the relevant information about the effects of the bowl geometry on the resonance.The CFD approach is validated against the experimental results of a real bowl geometry.
