2013年2月26日 · Thinner rings (say 2.8 mm) exert even less pressure, maybe as little as 7 lbs. of tension. With good bore geometry and the proper bore finish, low-tension rings are perfectly capable of maintaining adequate oil control. But a lot of engines that are running these thin, low-tension oil rings often turn out to be smokers.

2022年7月7日 · Piston Ring Thickness. The thickness of a piston ring is another important factor that influences its durability and sealing capabilities. Piston ring thicknesses typically range from 0.5 to 1.5 millimeters, with thicker rings generally providing greater strength and resistance to deformation. Piston Ring Radial Gap
Piston and Piston Rings - University of Washington
Piston rings seal the combustion chamber, conduct heat from the piston to the cylinder wall, and return oil to the crankcase. Piston ring size and configuration vary depending on engine design and cylinder material. Piston rings commonly used on small engines include the compression ring, wiper ring, and oil ring.
