Problems solved by technology

[0003] In the prior art, the engine thermal management simulation only uses a single one-dimensional cooling system simulation to evaluate the pros and cons of thermal management, and only analyzes the parts and parameters included in the cooling system, and cannot realize the system and components associated with the cooling system. The simulation analysis of the actual engine thermal management should not only include the cooling system, but also include multiple systems or components related to it, such as the lubrication system, the engine block, the radiator, and the heater core. Engine thermal management cannot be comprehensively and deeply simulated and analyzed

Description

technical field [0001] The invention relates to a one-dimensional integrated thermal management simulation method of an automobile engine. Background technique [0002] Engine thermal management simulation can reproduce and finally realize the control and optimization of heat transfer process, ensure the safe and efficient operation of key components and systems, rationally utilize heat energy, reduce waste heat emissions, and improve energy utilization efficiency. The significance of thermal management in terms of vehicle energy saving, environmental protection and comfort is becoming more and more prominent. [0003] In the prior art, the engine thermal management simulation only uses a single one-dimensional cooling system simulation to evaluate the pros and cons of thermal management, and only analyzes the parts and parameters included in the cooling system, and cannot realize the system and components associated with the cooling system. The simulation analysis of the a...
