重型汽车发动机冷却系总布置

Engine Cooling System General Layout of the Heavy-duty Truck

冷却系统的作用对车辆非常重要。资料显示，汽车故障的50％左右来自发动机，而发动机故障的50％左右由冷却系统的故障引起。由此可见，发动机冷却系统的作用对车辆非常重要，而冷却系统的总布置设计则是决定其性能的关键。

This paper summarizes the guidelines of the engine cooling system general layout and design which give the direction to the general layout and design of engine cooling system.
