What are the steps for cylinder measurement?

[IsabelaLee]

Cylinder measurement steps: 1. First clean the cylinder bore and adjust the dial indicator to the nominal size of the cylinder bore; 2. Measure six bore dimensions longitudinally and transversely at the upper, middle, and lower positions respectively; 3. The dimension with the largest deviation from the nominal size is considered as the maximum worn bore dimension after wear. Compare this value with the maximum tolerance of the bore diameter to determine the wear amount. Notes: 1. In the industry, cylinder wear refers to the diameter difference; 2. Select the maximum difference regardless of piston movement direction. A cylinder is a cylindrical metal component that guides the piston to perform linear reciprocating motion. In engine cylinders, air converts thermal energy into mechanical energy through expansion, while in compressor cylinders, gas receives piston compression to increase pressure.
