摘　　要：文章针对布置在增压发动机节气门前的中冷器机型介绍了一种热试台水循环改造方法,完成了中冷器的冷却循环系统在原有热试台冷却循环系统上的集成,以及发动机在冷却水加注、循环和排出时的控制策略,改造方法满足了发动机冷却水和进气中冷器冷却水的同步循环功能。最终通过发动机标准样机在热试台上运行的性能验证,确定了台架水循环改造的有效性。This article introduces a method of hot test bench cooling water circulation modification for the turbo-charged engine intercooler. Typically, the engine intercooler placed in front of the throttle. It completed the integration of the intercooler cooling circulation system on the original hot test bench cooling circulation, and the control strategy of cooling water filling, circulation and discharge. The modification method meets the synchronous circulation function of engine cooling water and charged-air intercooler cooling water. Finally, the effectiveness of water circulation modification is confirmed through the performance verification test of the standard sample engine on the hot test bench.
