The intake system provides the internal combustion engine with fresh air and it has a major effect on engine performance and emissions. Therefore great attention has to be focused on the design of the intake system. Many investigations are related to the improvement of the breathing capacity of the engine, to the minimization of pressure losses along the pipes and to the distribution uniformity of air among the cylinders of the engine. This paper deals with the design of the intake system of the racing car engine with special demands. The imposed constraint is a single circular restrictor in the intake system, positioned between the throttle and the engine. All engine airflow passes through this restrictor of 20 mm diameter for gasoline-fuelled cars. The only allowed sequence consists of a throttle, restrictor and engine. Keeping these requires in mind, the flow and pressure loss reduction in the engine intake region are investigated with computational fluid dynamics software. On the basis of numerically obtained results, the intake system is designed and practically manufactured in our racing car engine.
