Why is a cylinder hone used to create a cross-hatch pattern on the cylinder wall during an engine overhaul?

1. The microscopic scratches of the cross-hatch pattern retain engine oil, ensuring the piston rings are lubricated and can seat properly during break-in.
2. The pattern increases the cooling surface area of the cylinder wall, preventing overheating.
3. It smooths out the cylinder wall completely, reducing friction to zero.
4. The scratches help direct the combustion exhaust gases toward the exhaust port.
