进入秋冬季节,三、四轮农机大部分存在启动难的现象,大多是机油粘度发生变化引起的。因为农机多数是在春夏季节更换的机油,有的时间甚至更长。机油在高温高热条件下,会氧化成过多的胶质、沥青质,造成粘度过大,所以会引起柴油机的启动困难。 Into the autumn and winter, most of the three, four-wheel drive there is a difficult start-up phenomenon, mostly caused by changes in oil viscosity. Because most agricultural machinery is the spring and summer oil replacement, some time even longer. Oil under high temperature and heat conditions, will be oxidized into too much gum, asphaltene, resulting in viscosity is too large, it will cause the diesel engine start difficult.
