무단 변속 엔진 유체 팬 클러치 개발

This paper presents a discussion of the development of a viscous fan clutch with continuous linear variable speed control function for engine cooling system to improve cooling fan noise reduction and the overall fuel efficiency of the engine. It is well known generally that the operation of the engine cooling fan is one of the major noise. Vibration sourse in engine as well as the major power consumption device in engine. In the present study is has been shown that a viscous fluid fan driving clutch. For small and mediun diesel engine class(1 to 3.5 ton class). Having linear variable speed control function corresponding to cooling load and low temperature hysteresis has been developed. The results obtained has shown that the proposed design viscous fluid fan clutch can reduced the engine fan operational noise. Vibration as well as the cooling fan driving horsepower significantly.
