Three-dimensional Computational Fluid Dynamics (CFD) tools have become essential for research on Diesel engines. Indeed they help grasp the basic phenomena at stake, as combustion processes get more and more complex in order to comply with conflicting demands: more stringent emission standards and customer desire for research on Diesel engines. Indeed they help grasp the basic phenomena at stake, as combustion processes get more and more complex in order to comply with conflicting demands: more stringent emission standards and customer desire for "fun-to-drive" vehicles, i.e. higher torque and power outputs. CFD tools are however only as accurate as their physical submodels. That is why at IFP, injection, combustion and auto-ignition models are constantly evolving in order to keep CFD in pace with test bench innovations and demands. Such a close follow-up of CFD tools enables 3D computations to contribute actively in all IFP research projects on DI Diesel engines.
