The invention relates to the technical field of vehicle engines, and discloses an engine thermal management system and a forced exhaust method.The engine thermal management system comprises a whole vehicle controller, a whole vehicle warm air pipeline and a humidity sensor, and the humidity sensor is arranged in an engine exhaust pipeline; the whole vehicle warm air pipeline comprises a first warm air branch and a second warm air branch. A second electromagnetic valve is arranged in the second warm air branch; the vehicle control unit is connected with the second electromagnetic valve and the humidity sensor. When the humidity information in the exhaust pipeline of the engine is larger than the environment humidity value, the whole vehicle controller controls the second electromagnetic valve to conduct the second warm air branch, gas in the exhaust pipeline of the engine is forcibly exhausted, and therefore the problem that the exhaust pipeline of the hydrogen engine is frozen and blocked in the low-temperature environment is solved, and the service life of the hydrogen engine is prolonged. And the fault of blockage of the exhaust pipeline of the hydrogen engine is reduced, and the safety of the whole vehicle is improved.
本发明涉及车辆发动机技术领域,公开了一种发动机热管理系统及强制排气方法,包括:整车控制器、整车暖风管道和湿度传感器,所述湿度传感器设置在发动机排气管道内;所述整车暖风管道包括:第一暖风支路和第二暖风支路;所述第二暖风支路内设置有第二电磁阀;所述整车控制器分别与所述第二电磁阀以及所述湿度传感器连接;在发动机排气管道内的湿度信息大于环境湿度值时,通过整车控制器控制第二电磁阀导通第二暖风支路,将所述发动机排气管道内的气体强制排出,从而解决了低温环境下氢气发动机排气管路结冰堵塞的问题,减少了氢气发动机排气管道堵塞的故障,提高了整车的安全性。
