后置发动机汽车冷却系统的研究

通过对国内几种后置客车的试验研究，介绍了一种后置发动机车辆冷却系统的设计布置方法，并在计算机中引入安装效率。采用新的计算方法可计算冷却系统的气水温差，定量地分析冷却系统的冷却能力。

A study on Rear Mounted Engine Vehicle Cooling System

Based on the test and research on a few kinds of domestic buses, a design and layout method of vehicle cooling system with engine rear mounted is presented, and the installation efficiency is introduced in the calculation. Using the new method, the temperature between air and water can he calculated so that the quantitative analysis of cooling capacity of the cooling system can he made instead of the qualitative analysis. The latter is made by comparison amount of heat dissipation of the radiator got from approximated calculation and the amount of heal dissipation of the engine. The test result shows that the new developed design and calculation method is successful in resolving the problems in the vehicles with engine rear mounted.
