If the engine oil consumption is too much in Sinoteng construction machine. How can this problem be solved?
1. Oil leakage at the outer surface: check the locking condition of the each pipe and bolt of the engine oil pipeline. If it is found that the screw is loose, the gasket is damaged, and the pipe is broken, tighten the screw or bolt and replace the gasket and pipe respectively.
2. The oil filled in the crank case is too much. The engine can only be started after marking between “L (low oil level) and H (high oil level)” according to the oil gauge. If the oil level is lower than L, or higher than H, the engine shall not be started. The engine can be operated and handled if the oil level is between L and H.
3. The quality of the engine oil is not good or the mark is incorrect. Select and use the engine oil mark according to the engine oil mark or oil replacement period specified in various series of diesels of our company according to the chart.
4. There is oil leakage in the engine oil cooler. Check if there is engine oil in the cooling water. Replace the core of the engine oil controller.
5. Engine oil on the air compressor pump: since all the air compressors are introduced with a little amount of engine oil to lubricate the piston ring and moving parts. When this kind of engine oil is used for a certain period of time under the normal operation temperature of the air compressor, the gum deposit or carbon deposit will be generated. Therefore, it shall be checked. Replace it or eliminate the carbon deposit when necessary; carefully check the unloading valve to see if there is any carbon deposit. If the carbon deposit is serious, eliminate and clean. Also, check the cylinder end of the air compressor and the intake and outlet valves. Replace relevant parts when necessary. If the unloading valve is clean or there is slight carbon deposit, install new O ring on the body of the unloading valve and install new Y sealing ring in the hole of the unloading valve.
6. The air leakage amount of the crank case is big to make the engine oil jump out of the air port. Check the track for the loss of engine oil in the breather pipe. Check oil-gas separator and measure the air leakage amount. If the leakage amount exceeds 12 times of the displacement of the cylinder, check the abrasion of the cylinder jacket of the piston ring. Replace or repair when necessary.
7. The oil leaked from the turbocharger enters to the air intake or outlet pipe. The diesel is at the low-load operating status for a long term; the flexible sealing ring of the turbocharger loses its flexibility or is over-abraded. Properly improve the rotating speed load; replace the flexible sealing ring.
8. The sealing ring of the valve stem is abraded. Replace it.
9. The sealing of the piston ring is out of work. Replace it.
