  • Modeling Piston-Ring Dynamics, Blowby, and Ring-Twist ...

    1998-10-1 · A ring-dynamics and gas-flow model has been developed to study ring/groove contact, blowby, and the influence of ring static twist, keystone ring/groove configurations, and other piston and ring parameters. The model is developed for a ring pack with three rings.

  • Ring Groove

    The keystone ring has the added benefit that it can eliminate accumulated dust such as soot in the ring groove. This cleaning prevents gumming up or sticking of the ring in the groove, which in turn decreases ring groove wear. Diesel and two-stroke petrol engines frequently use this type of ring. Half keystone rings (the top ring in Fig. 4.8 ...

  • What is a keystone piston ring?

    2020-6-29 · What is a keystone piston ring? Keystone Ring: A compression ring with a wedge cross section. With its tapered sides, radial movement of the ring in engine operation will cause the axial clearance in the groove to increase and decrease. This greatly reduces ring sticking, as the ring continuously works its way free of the combustion residues ...

  • Piston Rings

    Piston rings are metallic gaskets that serve three important functions in an IC engine: SEALING: Prevent the combustion gases from escaping into the crankcase.
