Engine Warm-up 기간의 Zero Coolant 적용에 관한 연구

Abstract

Recently, there has been an interest in intelligent cooling system as it has the potential of achieving a better fuel economy and emission reduction. It is possible mainly due to the higher coolant temperature during engine warm-up and low speed/part-load conditions. Thus the purpose of our study was to investigate the relationship between zero coolant strategy and fuel consumption. A coolant flow test system was set for acquisition of coolant flow rate, pressure distribution and coolant temperature. Thease results were used for experimental data to validate the 1-D CFD code, Flowmaster2. From this study, we found that the zero coolant strategy improved fuel economy and emission reduction on the engine warm-up, and this results can be used for engine cooling system simulation model.
