Innovative Approach to Reduce Friction Losses in Turbocharger Thrust Bearings

Innovative Approach to Reduce Friction Losses in Turbocharger Thrust Bearings

Paper in proceedings outside WoS and Scopus

The mechanical efficiency of turbochargers is mainly influenced by the lubrication system and can be increased by improving the performance of the thrust bearing. An innovative approach combines three levels of bearing computational models with optimization using genetic algorithms and effectively considers the multi-operating conditions. The strategy represents a 35% reduction in mechanical losses of the thrust bearing under preferred operating conditions. These savings result in a 20% energy saving in the lubrication system measured on the turbocharger of a stationary internal combustion engine without significant risk of lubrication system failure.
