The invention provides a low-temperature quick start heating system and a low-temperature quick power take-off method for a special vehicle. A waterway circulation mode for simultaneously and circularly heating multiple cylinders of the engine is realized by using a bypass switching mode of a heat dissipation cooling pipeline of the engine and a transmission, and the engine can be quickly started in an extremely cold environment within a short time (within 8min). Meanwhile, a low-temperature starting pipeline switching protection circuit is provided, so that a driver can operate by one person in a cab, switching between a low-temperature device water path and a gearbox oil-water exchanger water path can be achieved, and the abnormal conditions that the oil temperature of a gearbox is too high during driving due to the fact that switch switching is not in place due to operation are avoided. According to the rapid power take-off method in the low-temperature environment, a transmission power take-off operation method in the low-temperature environment is provided according to the starting combustion characteristics of the engine in the low-temperature environment, it can be guaranteed that power take-off success (13min) of a vehicle in the low-temperature environment can be rapidly achieved, and the rapid response time of vehicle equipment is guaranteed.

    本发明提供了一种特种车辆低温快速起动加热系统及低温快速取力方法。使用发动机与变速器散热冷却管路旁通切换的方式来实现对发动机多缸同时进行循环加热的水路循环方式,可以在短时间(8min以内)完成发动机在极寒环境下的快速起动。同时提供了低温起动管路切换保护电路,使驾驶员在驾驶室内一人进行操作,即可实现低温装置水路与变速箱油‑水交换器水路的切换,避免因操作引起的开关切换不到位使行车时变速箱油温过高等异常情况。本发明提供的低温环境下快速取力方法,根据低温环境下发动机的起动燃烧特性提供了一种低温环境下变速器取力操作方法,可以保证车辆在低温环境下快速实现取力成功(13min),保证了车辆设备快速反应时间。
