작동 유체의 동압력을 이용한 내연기관의 과급장치 개발

In this paper, we proposed a new boosting device for internal combustion engines using dynamic pressure. The boosting device is inspired by the concept of boost converter in electrical system. The proposed boosting device is composed of a fan blowing air into an intake manifold, a bypass, and a bypass valve. By using the fan and the bypass valve, kinetic energy of a working fluid is translated into pressure energy. Consequently, the intake manifold pressure is increased due to the pressure energy. The feasibility of the proposed boosting device was validated by a commercial 1-D engine model, GT-power.
