冬季使用压路机,启动机得不到所需的输出功率,难以达到启动转速的要求;同时,曲轴转速不高,进气管温度和气体流速都低,燃油雾化质量差,因此难以启动。冬季低温,润滑油流动性差,降低了润滑效果,加剧了发动机和传动部件的机件磨损,转动部件运转时搅油功率损失增加,发 Winter use of roller, the starter can not get the required output power, it is difficult to achieve the starting speed requirements; the same time, the crankshaft speed is not high, intake pipe temperature and gas flow rates are low, poor quality of the fuel atomization, it is difficult to start. Winter low temperature, poor mobility of lubricants, reducing the lubrication effect, exacerbated the engine and transmission parts of the wear and tear, rotating parts operating agitation power loss increases, the hair
