Over the last few years, computational fluid dynamic codes for automotive engines application have improved dramatically. As a result of the enormous improvement in the code numerics (more than mathematical modelling) and computer hardware, three- dimensional steady or unsteady flow computations are now feasible as a standard engine design decision support tool. This paper presents the application of three-dimensional fluid dynamic computations to the optimization of inlet valve and port shape as well as of cylinder head and piston shape in a high performances high speed 5 valve spark ignition engine.
