摩托车用的小排量发动机因要求采用轻量且结构简单的冷却装置,一般采用的是风冷系统,而轻型汽车及配装大排量发动机的摩托车则要求具备优异的环保性能、动力性能及静音性,所以普遍采用水冷系统。这2种冷却系统都是常用的发动机冷却方式。回顾了日本本田技研工业公司在开发轻型汽车发动机的过程中由风冷方式向水冷方式转变的过程,同时,介绍了目前发动机冷却系统的新技术和新动向。
Small displacement engines for motorcycles generally require air-cooled systems due to their lightweight and simple structure. Light-duty vehicles and motorcycles with large displacement engines require excellent environmental performance and power Performance and quietness, it is generally used water-cooled system. These two cooling systems are commonly used engine cooling. It reviews the process of Japan Honda Motor Co., Ltd. in the process of developing light vehicle engines from air-cooled to water-cooled. At the same time, introduces the new technology and new trends of the current engine cooling system.
