The invention relates to an engine cold start auxiliary system, a control method and a motor vehicle. The engine cold start auxiliary system comprises a warm air heater connected with an engine cooling liquid outlet through a pipeline, and an outlet of the warm air heater is connected with a defroster and a radiator through a warm air electromagnetic valve and a pipeline; an outlet of the warm air heater is connected with a cooling liquid inlet of the engine through a pipeline and a preheating electromagnetic valve. Outlets of the defroster and the radiator and an inlet of the preheating electromagnetic valve are jointly connected to the cooling liquid inlet of the engine through pipelines. And the warm air electromagnetic valve and the preheating electromagnetic valve are interlocked, are respectively connected with the preheating switch and are jointly controlled by the preheating switch. The engine is preheated in a warm air heater short circuit mode through the two sets of interlocked electromagnetic valves, and when the engine is preheated to a certain temperature, the engine is started through automatic prompting of an instrument.

    本发明涉及一种发动机冷启动辅助系统、控制方法及机动车辆,包括通过管道与发动机冷却液出口连接的暖风加热器,暖风加热器的出口经暖风电磁阀通过管道分别连接除霜器和散热器,暖风加热器的出口通过管道经预热电磁阀连接发动机的冷却液入口,除霜器和散热器的出口与预热电磁阀的入口通过管道共同连接在发动机的冷却液入口处;暖风电磁阀为常开电磁阀,预热电磁阀为常闭电磁阀,两者为互锁且分别与预热开关连接共同受到预热开关的控制。利用互锁的两组电磁阀以暖风加热器短路的方式为发动机进行预热,当发动机预热到一定温度,通过仪表的自动提示,启动发动机。
