Poor fuel combustion

Fuel injection pressure is too low, the injector drops oil, fuel injection atomization and oil supply time is too late will cause fuel combustion and lead to cylinder knocking. The sound that this kind of fault causes to knock cylinder is low, hoarse and accompanying engine overheat, black smoke or vent pipe blast, exhaling phenomenon. The injector shall be removed for inspection and adjustment, and the oil supply time shall be adjusted. If necessary, a new part shall be replaced to meet the requirements.

Oil outlet valve is worn

After the oil valve is worn, on the one hand, the clearance between the relief ring and the inner hole of the valve seat becomes larger, the tightness becomes worse and the relief effect becomes worse. On the other hand, the residual pressure in the high-pressure tubing is too high, which increases the oil supply, causing fuel deflation and knocking on the cylinder.

Common problems

Troubleshooting of cylinder cushion

Cylinder engine pad is a common fault. Impact cylinder pad can take many common forms of abnormal sound. Because the cylinder cushion is washed away to different degrees, the resulting abnormal sound is different.

Close the tank to check, they found abnormal noise in the VI cylinder. Suspect the injector needle is eye-catching. Delete the normal check results.

The sixth cylinder head was removed, we found that the cylinder pad burned smoke, the cylinder head bolts were originally tight (torque up to 250N · m) phenomenon, while the cylinder head and cylinder pad were not compressed because there was a water block higher than the upper body flat. Replace the cylinder pad and just get off the plane, re-noise after losing the mounting height of the block, and the engine runs normally.
