摘　　要：46 5Q汽油机的冷却水套设计结构造成局部水流速度太低 ,致使大负荷时发生局部过热问题。运用流体力学和传热学的概念 ,采用提高水流速度的措施来改进 4 6 5Q的冷却系统 ,并将改进措施应用在JT4 6 8Q汽油机上 ,解决了局部过热问题。The local overheat occured in the water jacket of 465Q gasoline engine, because the structure of the water jacket made the water flow speed too low at some positions under full load operation conditioon. From the viewpoints of hydrodynamics and heat transmission, the 465Q engine's cooling system was improved by increasing the water flows peed. Thsures have been applied to JT468Q gasoline engine, therefore the local overheat is resolved.
