수퍼차저의 과급 성능 특성에 관한 연구

The purpose of this paper is to show the performance charateristics of Roots type supercharger with two lobe rotor. The performance test were conducted to obtain the drive power, volumetric efficiency, and the influence performance factors of supercharger. With the flow characteristics of supercharger, the effect of the operating conditions on supercharger performance was investigated. The results show that the increase of supercharger speed and pressure ratio bring about the increase of drive power.
