摘　　要：针对传统大功率柴油机冷却系统智能化水平低,冷却系统存在部件可控性差,功率消耗大,冷却不足或过度冷却等缺点,对柴油机冷却系统进行了智能化改进,并进行了全工况热平衡试验,掌握了各工况下发动机热平衡状况.通过与改进前发动机的热平衡试验数据进行对比分析,得到发动机在安装ECU及高低温双循环电控阀和电控水泵等智能化控制部件后,发动机进气温度得到合理控制,燃料燃烧更加充分,提高了热工转换效率及工作稳定性和可靠性.Because of the low intellectualization level of the traditional high-power diesel engine cooling system, cooling system exists problems such as high power consumption rate, difficult of control, insufficient cooling or excessive cooling and so on. We improve the engine＇ s cooling system intelligence and obtained all regime heat balance condition of the engine by all regime heat balance test. The test data show the intelligent control cooling system can improve the air entry condition and burning condition, increase power conversion efficiency, working stability, reliability of the engine.
