Abstract
Recently, mechanically driven superchargers are being manufactured and applied to engines in order to increase the torque in low speed range and improve acceleration response. In our study, four types of positive displacement superchargers were picked up and the engine performance tests were carried out with each of them. The results were compared to each other, and finally, the advantage of a screw type supercharger was confirmed.
At the same time in this paper, three types of high technology turbochargers are introduced, which are superior to the conventional ones from the viewpoint of low speed characteristics, transient response, and so on. Effectiveness of high technology turbochargers were described here with the test results.
