Generally speaking, excavators with good equipment will emit colorless and transparent gas under normal working conditions. Excavator engines that are not running well will emit other colored smoke, but no matter what color, an experienced excavator will know what happened to the excavator at a glance. Why does the excavator emit white smoke? You will know after reading this article!
Failure phenomenon: a 6,000 hours of Komatsu PC270-8 excavator engine oil pressure 4-5 kg, exhaust pipe exhaust a lot of oil out, exhaust pipe also emits a lot of white smoke.
Failure analysis:
1. Could it be that the fuel injection nozzle is not working? Diesel has leaked into the engine oil? The engine oil is full?
2. The exhaust pipe of the excavator emits white smoke and the exhaust pipe drains the oil, indicating that the excavator engine is gasping.
3. Komatsu PC270-8 excavator exhaust pipe exhaust oil has white smoke. The reason may be that the pressure of the excavator engine is low.
Fault check:
1. It is recommended to check each valve guide.After the guide is worn, the clearance is large, and the oil that lubricates the rocker arm may flow into the cylinder head when the valve moves up and down. Enter the cylinder and burn.
2.The temperature of the exhaust pipe is very high, and it is normal to emit white smoke after the oil flows in, but the temperature cannot reach the ignition point of the oil.
3. As for the problem of high water temperature, if the engine burns oil, the efficiency will be greatly reduced, the carbon deposit will also increase, and the water temperature will increase if the efficiency is low.
4. The engine oil can flow out of the exhaust pipe, and the valve guide has a problem.
5. If there is white smoke in the exhaust pipe exhaust of the excavator, it is not burning the engine oil. It must not be installed after the overhaul.
