一、冷启动后未暖机就带负荷运转柴油机冷机启动时,由于机油黏度大、流动性差,使机油泵供油不足,机器摩擦面因缺油润滑不良,造成急剧磨损,甚至发生拉缸、烧瓦等故障。因此,柴油机冷启动后应怠速运转升温,待机油温度达到40℃以上时再带负荷运转;机器起步应挂低速挡,并循序在每一挡位行驶一段里程,直到油温正常、供油充分后,方可转为正常行驶。二、柴油机在机油不足时运转此时会因机油供给不足而造成各摩擦面供
First, the warm start after cold start with a load run Diesel cold start, due to the oil viscosity, poor fluidity, insufficient oil pump, the machine friction surface due to poor lubrication, causing rapid wear and tear, and even pull cylinder , Burning tiles and other failures. Therefore, the diesel engine should start running at idling speed after the cold start. When the temperature of the oil reaches above 40 ℃, it should be loaded with the load. The machine should start with low speed gear and drive the mileage of each gear step by step until the oil temperature is normal and the oil supply is sufficient After the transfer can be normal. Second, the diesel engine runs low oil at this time due to insufficient supply of oil caused by the friction surface for
