摘　　要：传统发动机冷却系统由于自身的被动性影响,其工作性能受到限制。在部分负荷时会造成功率损失,而汽车在此工况下行驶的时间最长。介绍一些先进冷却系统的设计和工作特点,这些系统既能起到保护发动机的作用, 又能改善燃油效率和降低排放污染物。The performance of the conventional engine- cooling system is always constrained by the passive nature of the system. This leads to considerable losses in the cooling system at part - load conditions where vehicles can operate most of the time. A set of design and operating features from advancedengine cooling systems is reviewed and evaluated for their potential to provide improved engine protection while improving fuel efficiency and emissions output.

关 键 词：发动机冷却系统 燃油效率 排放量 发展趋势 功率损失 排放污染物
