１．机油压力不足 柴油机在最低怠速运转时机油压力应不低于４９ｋＰａ，当柴油机正常工作时机油压力应为１９６～３９０ｋＰａ。若油压达不到规定值，说明润滑系统有问题。供油量不足就不能很好地润滑和冷却，可能导致机械事故。 当油压表指示的油压不足时，可能有以下几个原?
1. Insufficient oil pressure The engine oil pressure should not be lower than 49kPa when the engine is running at the minimum idle speed. The oil pressure should be 196 ~ 390kPa when the diesel engine is working normally. If the hydraulic pressure does not reach the specified value, there is a problem with the lubrication system. Insufficient fuel supply can not lubricate and cool well, which can lead to mechanical accidents. When the hydraulic gauge indicated insufficient hydraulic pressure, may have the following original?
