1.润滑油不足或供油滞后 (1)当涡轮增压器的转速和柴油机负荷增加时,涡轮增压器润滑油的供油量也必须增加,因为柴油机高负荷运转、涡轮增压器转速很高时,即使只有短暂的几秒钟对涡轮增压器轴承供油不足也将造成轴承损坏。 (2)在更换机油和机油滤清器时,用清洁的机油预先注满滤清器,换完后第一次启动柴油机时,应在柴油机启动后保持足够长时间的怠速运转直到机油压力稳定后再加速,否则涡轮增压器的轴承就可能因启动期间缺乏润滑而损坏。 (3)当柴油机处于倾斜状态下工 1. Lack of oil or fuel lag (1) As the turbocharger speed and diesel load increase, the turbocharger oil supply must also increase because of high engine load, turbocharger speed High, even if only a few short seconds on the turbocharger bearings insufficient oil will also cause bearing damage. (2) In the replacement of oil and oil filter, pre-filled with clean oil filter, the first time after the start of the diesel engine, the diesel engine should be maintained for a long enough time to start idling until the oil pressure is stable Then accelerate, otherwise the turbocharger bearing may be damaged due to lack of lubrication during start-up. (3) When the diesel engine is in a tilted state
