First, the power decreased significantly. When the throttle is placed at the maximum position, the maximum output power of the diesel engine is only about 60% of the rated power, and the load is obviously not configured. The power of the fuel oil, gas distribution mechanism, crankshaft connecting rod mechanism and other related parts can not be recovered after the maintenance and adjustment.
Two, fuel consumption increased significantly. The oil consumption exceeds the rated 30% – 50%, and the oil consumption of the engine is more than 1 times the rated value. The exhaust takes out oil, the crankcase breather (or gas inlet) carries oil mist smoke, and the crankcase temperature increases significantly.
Three, Baotou north and North running parts, cylinder, piston and other parts wear seriously. The wear of the cylinder, piston and crankshaft of the north and the north of Baotou has exceeded the limit value. The wear of the fittings of the air distribution mechanism is serious, which makes the seal of the cylinder liner become worse and the cylinder pressure lower.
Four, can not successfully start. After the shutdown, the cooling water temperature is 50 DEG C – 60 cases, can not start smoothly and the engine operating temperature 70 to 90 DEG C, the cylinder from the piston and piston pin, main bearing or Baotou North Benz at the sound of the connecting rod bearing.
