寒冷的冬季,气温急剧下降,尤其是北方,风雪迷漫,寒气逼人。在严寒的气候中不但行车艰难,而且起动发动机也并非是件简单的事情。 尤其是柴油发动机,在低温的条件下,要费好大的力气方可起动。究其原因,主要是在低温时,燃油与空气混合雾化差,或者不易使燃油与气体压缩燃烧。与此同时,由于润滑油在低温时粘度较高,使转动曲轴所需的扭矩增大,既限制了起动机转动曲轴的 The cold winter, the temperature dropped sharply, especially in the north, romantic snow, cold pressing. Not only is driving difficult in a cold climate, it is not a simple matter to start the engine. Especially diesel engine, under the condition of low temperature, it takes great effort to start. The reason is mainly at low temperatures, the fuel and air mixed atomization is poor, or not easy to make the compressed fuel and gas combustion. At the same time, due to the higher viscosity of the lubricating oil at low temperatures, the torque required to rotate the crankshaft is increased, limiting both the crankshaft rotation of the starter
