(1)发动机启动后,机油压力逐渐下降至规定值以下,甚至降到0。其原因多因曲轴主轴瓦、连杆瓦或凸轮轴套严重磨损,配合间隙增大,当机油温度升高使粘度下降时,机油从这些间隙处大量泄漏;另一种原因是限压阀和回油阀磨损,密封不严而造
(1) After the engine is started, the oil pressure gradually drops below the specified value, even down to zero. The reason for the crankshaft main bearing, connecting rod or camshaft bush serious wear and tear, with the gap increases, when the oil temperature increases the viscosity drops, the oil leaks a lot from these gaps; Another reason is the pressure limiting valve and Return valve wear, lax seal made
