Internal combustion engines are machines that convert thermal energy into work, and in order to improve output performance, it is important to burn as much fuel as possible. The three main factors for improving output performance are increasing the intake volume, accelerating combustion, and reducing friction. Among these factors, the intake volume directly affects the output performance of the engine. In this study, we focused on the shape of the intake system to increase the intake air volume and ensure uniform air distribution between cylinders. We compared the flow rates between cylinders using CFD analysis and evaluated the intake shape. As a result, changes in the intake air flow rate between cylinders were confirmed.
