Schaffler Agrees Uniair Cooperation With ABB
Schaeffler and ABB Turbo Systems AG have signed a cooperation agreement with regard to the Schaeffler valve-control system, Uniair. The collaboration agreement will see ABB contribute its knowledge of efficient, single- and two-stage turbocharger technology, as well as marketing and sales of large, high-performance engines. The cooperation applies to units with a performance of 400kW (544 PS) per cylinder or higher. The applications of these large engines are typically in marine, machinery and stationary operation. The advantages of the VVT system in conjunction with high-pressure turbocharging are in the fields of emission- and fuel-consumption reduction and in the improvement of the start, part load and acceleration behaviour. The Uniair fully variable, hydraulic valve-control system is behind the VVT system and enables the variation of valve timing and lift. The Alfa Mito 1.4 Multiair is the first vehicle to utilise this technology, which is branded 'Multiair' by Fiat. The ...
