Difference between engine cylinder failure and cylinder scuffing

Engine cylinder failure and cylinder scuffing are common truck faults.

Engine cylinder failure refers to the phenomenon that one or more cylinders of the engine do not work or do not work enough. If a 4-cylinder engine has one cylinder that does not work and only three cylinders work, the fault is called cylinder failure. Or if all four cylinders do not work smoothly and cannot work completely, it is also called cylinder failure. The failure of cylinder failure can only be accurately detected by computer detection. The fault code on the computer will clearly tell which cylinder is missing, and then the corresponding repair can be performed.

The most obvious phenomenon is severe engine vibration, and the engine fault light will also light up. Because one cylinder is failed, the engine will run unbalanced, causing severe vibration. At this time, acceleration will become weak and difficult to speed up. Fuel consumption will also increase significantly because the fuel of the non-working cylinder is wasted.

Cylinder scuffing means that the inner wall of the cylinder is abnormally worn, and there are scratches or scrapes on the cylinder wall. This is a more serious fault and requires an engine overhaul to solve it. Cylinder scuffing will also cause the vehicle to lack power, and there may also be noise and oil burning, so it must be repaired in time. 

There are many reasons for cylinder scuffing, the most common one is high water temperature. The second is that the engine oil is invalid, or the engine oil has not been changed for too long, resulting in insufficient lubrication, no good lubrication between the piston ring and the cylinder, and long-term friction. Finally, the quality of gasoline is poor, which keeps the engine in a state of detonation. The piston and the cylinder wall often hit and collide with each other, causing damage to the cylinder wall.
