摘要
利用Simulink建立了一个柴油机冷却系统模型,利用这一模型对柴油机冷却水温作出预测,为节温器及水温传感器的诊断提供了重要依据。最后在YC6112ZLQ柴油机上进行了试验,证明模型值与实测值的最大误差小于5%,并能满足实时性的要求。
A coolant temperature model based on Simulink was built to predict diesel engine water temperature,which is helpful for ECT and thermostat fault diagnosis.Finally the model was validated on YC6112ZLQ diesel.It was proved to meet the accuracy and reliability.
