摘要
本文对电子节温器控制内燃机冷却液温度进行了研究。首先分析了冷却液温度控制的原理,根据不同内燃机工况并考虑内燃机安全性等因素确定目标冷却液温度;利用模糊控制的原理来控制节温器升程,由升程和实际温度推算出节温器加热占空比,进而控制冷却液温度;在升程达到最大升程时,通过两级冷却电子风扇的配合进行冷却。在此基础上,分别通过转毂NEDC循环和道路实车测试验证了控制策略的可行性。试验结果表明,冷却液温度能控制在目标温度附近,该系统能够满足工程设计需求,且NEDC油耗测试循环中节油率约为1.27%。
An electronic thermostat is used for the control of coolant temperature of internal combustion engine.The principle of coolant temperature control is analyzed,and the optimal objective coolant temperature is determined based on the working condition of internal combustion engine and its safety.The fuzzy control principle is applied to the control of the lift of thermostat,and then thermostat heating duty cycle is acquired according to the lift and the current coolant' s temperature.Two under hood cooling fans will be activated,especially when the thermostat lift reaches on its maximum.To verify the strategy of electronic thermostat,NEDC bench test and real vehicle test are both taken.Result shows that the water temperature can be controlled corresponding to the optimal objective coolant temperature,and the control system completely satisfies the requirement of project design,and save oil about 1.27% in NEDC test.
