目前,我国东北、西北、内蒙和西藏等地区,解放牌汽车在野外远离基地执行运输任务,在温度低于-10℃时,大多数汽车是没有保温设施的。通常采用起动前预热发动机的方法发动车辆,给驾驶人员带来许多困难,发动车辆的时间长,不能充分发挥车辆的效能。为了解决这个问题,我们从1979年冬开始研究解放牌汽车在低温条件下不预热发动机的冷起动 At present, in the northeast, northwest, Inner Mongolia and Tibet areas of China, Jiefangpai vehicles are away from the base in the field to carry out transportation tasks. At temperatures below -10 ℃, most vehicles do not have thermal insulation facilities. It usually takes the method of preheating the engine before starting to start the vehicle, which brings many difficulties to the driver. It takes a long time to start the vehicle and can not give full play to the performance of the vehicle. In order to solve this problem, we started from the winter of 1979 to study the liberation of the brand cars at low temperatures without preheating the engine cold start
