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. For fuel, gas distribution mechanism, Baotou North rush heavy truck parts, crankshaft, connecting rod mechanism and other related parts, after maintenance and adjustment, the power can not be restored.
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 rush heavy truck parts, cylinder, piston and other parts wear seriously. The wear of the cylinder, piston and crankshaft all exceeds the limit value, and the wear of the fittings of the valve 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 beiben heavy truck accessories at the sound of the connecting rod bearing.
