Driving engine efficiency

摘要

A collaboration between the Schaeffler Group and Fiat Powertrain has resulted in the development of what is claimed to be the world's first fully variable hydraulic valve-control system for car engines.rnThe Uniair system was originally developed by engineers at the Centra Ricerche Fiat (CRF). In 2001 Fiat granted a licence to Schaeffler to continue to develop the technology and inrn2003 the first functioning Schaeffler prototype car was available, with further prototype vehicles manufactured two years later. Inrn2004 the development of the Fiat Fire Multiair engine was started.
