The gap between the ring and the liner is in general defined as: (5) h (x, y, t) = h m (t) + S (x) + δ (p) + Δ (y, t) Due to the relatively low pressure values in the ring-liner contact (of order of a few hundred MPa) no localised deformation of the contiguous surfaces is expected (Mishra et al. and Ma et al. ), thus: δ = 0.

  • How Piston Rings Affect Horsepower - Engine Builder

    2011-2-25 · Of the three rings in a typical ring pack, the oil ring accounts for 60 to 70 percent of the total friction created by the rings. Reducing ring friction by using smaller, thinner low tension rings can allow you to “find” horsepower that was previously lost. Low tension rings reduce friction and allow an engine to produce more usable horsepower.
