TURBO CHARGER

摘要

PURPOSE: A turbocharger is provided to increase air speed by a fast rotary speed and a wide contact area between a compressor wheel and the air. CONSTITUTION: A turbocharger comprises a compressor wheel(40), a compressor housing(32), a turbine housing(34), and a turbine wheel(60). The compressor wheel pulls in the air by rotating. The compressor wheel is placed in a hollow portion of the compressor housing. The turbine wheel is placed in the turbine housing, and connected to the compressor wheel with a shaft. A blade unit of the compressor wheel is unfolded in a radial direction, and the contact area between the air and a blade unit increases when the rotary speed of a rotary center unit in the compressor wheel becomes faster.
