Design and Analysis of an Operative Inlet

[摘要] This paper describes the effect of intake manifold with the application of intake runner as the operative inlet used in racing car that participate in Formula Student (FSAE) competition. The design analysis of the runner is carried out to give uniform distribution of the air flow getting into engine. Air flow behavior plays an important role in order to provide better air fuel mixture inside the intake manifold before it is drawn to the combustion chamber. The results from this study indicate that longer runner gives low percentage of pressure loss but cause the air velocity to drop. Changing the outlet diameter of runner gives higher velocity at the smaller diameter and highest angle resulted higher air mass flow rate inside the runner. The new design of runner is built of 60mm length, 55mm outlet diameter and 55° angle and the results show 0.05% improvement occur in air flow distribution at the end of each runner outlet.
