자동차용 서머스탯의 최적설계 변수설정에 관한 연구(Ⅰ)
박경석(K.S.Park),신진석(J.S.Shin),원종필(J.P.Won) 한국자동차공학회 1992 한국자동차공학회 춘 추계 학술대회 논문집 Vol.- No.-
It is widely recognized that exhaust emissions. fuel economy<br/> and engine torque are affected by engine temperature. and logic would suggest that a cooling system offering a better compromise of engine temperature would improve both overall engine<br/> performance and economy.<br/> Author measured coolant temperature of some parts and flow<br/> rate which are necessary to heat transfer in a engine. And<br/> Author determined parameters necessary for the optimum design of a thermostat to keep the best engine performance: determined the optimum operating temperature of electric cooling fan.<br/> A summary of this study is followed.<br/> 1. Study of the effects of cooling condition to combustion character in a engine. <br/> 2. Analyze of heat transfer surrounding engine cylinders.<br/> 3. Study of the effects of cooling character to engine heat<br/> rejection. determination of the optimum coolant temperature for keeping the optimum engine performance and determination of the optimum design of a thermostat for keeping that temperature.<br/>
