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


  • Ring pack optimisation, reduction of friction, blowby, oil consumption and wear
  • Influence of oil properties on ring pack performance
  • Diagnostic tool to assist with ring pack development 

Key Features

  • Piston ring dynamics
  • Gas dynamics model computes the mass flow of gas past each ring and 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
