What Are the Causes of Excessive Cylinder Pressure?

[VanValentina]

Causes of excessive cylinder pressure: 1. Excessive carbon deposits in the combustion chamber; 2. Excessive grinding of the joint surface between the cylinder block and cylinder head. Under normal circumstances, the wear on the cylinder along the working surface in the piston ring movement area forms an irregular cone shape that is larger at the top and smaller at the bottom. Methods for diagnosing cylinder wear faults include: 1. Measuring the pressure of the faulty cylinder; 2. Measuring the cylinder diameter and cylindricity. A cylinder is a cylindrical metal component that guides the piston to move linearly back and forth within it. In an engine cylinder, air expands to convert thermal energy into mechanical energy, while in a compressor cylinder, gas is compressed by the piston to increase pressure.
