RINGPAK

RINGPAK

RINGPAK

RINGPAK is an advanced two-dimensional simulation package for predicting ring-pack dynamics, lubrication and gas flow for optimization of the ring pack. Based around advanced lubrication, gas and ring dynamic models, the engineer is able to reduce friction, wear, blow-by and oil consumption, minimizing the need for expensive and difficult testing.

Key features

  • Piston-ring dynamics
  • Gas dynamics model computes the mass flow of gas past each ring, plus inter-ring pressures
  • Hydrodynamic and boundary lubrication models
  • Advanced oil-consumption calculations
  • 3D effects, including piston secondary motion from PISDYN and bore distortion from FEARCE
