- Cylinder de-activation (CDA) is increasingly used to minimise frictional power loss and this was investigated in the present study. New numerical solutions of the Navier-Stokes equations for multi-phase flow (oil, air and vapour) have been developed for big-end bearings. Predictions compare favourably with long standing experimental measurements of circumferential bush and journal surface temperatures and film pressures. The findings show that whereas reduced pumping losses and fuel consumption can be achieved with CDA, the power loss in big end bearings can increase if the output power is maintained.
