车用发动机热平衡研究进展与展望

Research Progress and Prospect on Thermal Balance of Vehicle Engine

以发动机热量分配、热负荷及冷却系统智能控制为切入点,综述了车用发动机热平衡研究的现状,并探讨了进一步的发展方向。指出针对我国特殊的高原环境,进行极端工作环境下热量分配变化规律的研究、发动机热平衡模拟试验技术研究、开展高原环境柴油机冷却系统智能控制研究,以最优化匹配散热需求是未来发动机热平衡研究的方向。

With heat distribution and heat load of engine as well as intelligent control of cooling system as the starting point, this paper summarized the current situation of thermal balance research of vehicle engine and discussed the further development direction. It pointed out that for the special plateau environment in China, we should focus on the mechanism of heat distribution change in extreme working environment, research on engine thermal balance simulation test technol-ogy, and carry out the intelligent control of the cooling system of the plateau environment diesel engine to optimize the matching heat dissipation requirement in the thermal balance research of engine.
