摘要：This paper emphasizes on designing and optimization of exhaust headers for FSAE car engines and ituses the art of wave dynamics to maximize wave scavenging potential during valve overlap period.The main objectiveof designing exhaust headers are to enhance engine breathing by minimizing backpressure at high rpm and exhaustpulse tuning to maximize wave scavenging potential during valve overlap period. The virtual engine model has beendeveloped in Ricardo Wave Software and analysis of the performance changing factors have been done. This workstudies the performance of different geometries using Ricardo Wave Build by analyzing the torque curve, power curve,port pressure as well as vol. efficiency and also their effects are discussed.Track data of Formula SAE was gathered,and according to the optimum engine running condition, the tuning goal was achieved. Structural analysis was alsocarried out using different materials with weight reduction being the paramount factor accounting for it.
