Optimized design of engine intake manifold based on 3D scanner of reverse engineering

Abstract : It is difficult to design the engine intake manifold in normal method because of the complex structure, and the real situation of fluid movement in the manifold cannot be obtained through the steady flow test, so the optimized design is proposed about the engine intake manifold based on reverse engineering. A3D model of the intake manifold is build according to the CATIA software; fluid mathematical is set up by computational fluid dynamics method. The 3D geometry model of the intake manifold is grid with the Gambit software and the divided grid data is imported into the Fluent. These are performed about the simulation of the fluid pressure field, velocity field, flow field, and local flow field in the manifold. Key parameters design of the intake manifold relies on the results. It proves that the reverse technology is reasonable for the intake manifold design through the theory and simulation analysis; it can ensure sufficient air intake and reduce the intake resistance and energy loss of the air, and can improve the air intake uniformity.
