Abstract
Measures to reduce friction in internal combustion engines are moving up the agenda for developers. This article presents the opportunities offered by replacing plain bearings with rolling bearings, using crankshafts and camshafts as examples. The rolling bearings in balancer shafts are described in close detail to demonstrate the outstanding cost/benefit ratio achieved with this measure. In addition to avoiding mechanical losses, the approach being pursued at INA creates a whole host of other opportunities for optimisation that may result in a reduction in CO2 emissions.
