Gasoline stainless steel exhaust manifold airflow performance, thermal stress, thermal mode, performance thermoplastics such as numerical analysis

As cars become a trend and lightweight supercharged engine exhaust temperature brought, stainless steel exhaust manifold has been widely used with gasoline engines. Therefore, this paper has important value engineering studies Gasoline stainless steel exhaust manifold heat load. Analysis, combined with the simulation results to optimize the structure of the exhaust manifold designed to meet product  Stainless steel needle valve  of this article for a gasoline engine airflow performance stainless steel exhaust manifold, heat stress, heat mode, the thermoplastic properties of numerical simulation. Firstly, the flow field through a mathematical model,  Valve manifold  knowledge of fluid dynamics, simulation software for the flow field in the case of the engine exhaust manifold all conditions of different cylinders turned analyzed were obtained pressure distribution and flow lines distribution.
