- Summary:
- The influence of engine cooling fan on the working state of engine cooling system under different driving forms and control strategy is studied, and a simulation model of engine thermal management system of a commercial vehicle is established. The model takes into account the measured performance parameters of the cooling system components, the gear shift logic of the transmission, the effect of vehicle speed on the airflow rate of the radiator, and proposes a modeling method for different cooling fan driving forms. The performance parameters such as engine outlet coolant temperature and corresponding cooling fan speed under different vehicle speeds and engine loads are calculated and analyzed by using the established model. The road measurement test of the engine thermal management system under the same working condition was carried out to read the relevant data from the engine ECU and confirm the reliability of the data. The correctness of the model is proved by the comparison between the model calculation results and the test results. Based on the established model, the working characteristics of the cooling fan driven by the electronically controlled silicone oil clutch are analyzed, and the improvement method of the control strategy of the electronically controlled silicone oil clutch is proposed. The results show that the cooling fan driven by the electronically controlled silicone oil clutch can adaptively adjust the fan speed, reduce the power consumption of the engine, and make the engine work at the optimal temperature by using the improved control strategy of the electronically controlled silicone oil clutch established in this paper
