Why Should the First Ring Face the Intake Direction?

[JustinLee]

Because the first ring experiences high exhaust temperatures, it is best to face the intake direction. The compression ring, also known as the piston ring, is used to seal the gap between the piston and the cylinder wall, preventing gas in the cylinder from leaking into the oil pan and transferring heat from the piston head to the cylinder wall, which is then dissipated by coolant or air.
