NewsSouth-East European INDUSTRIAL Мarket - issue 5/2009

The Schaeffler Group and the ABB Turbo Systems AG have signed a cooperation agreement. The content of the collaboration with the turbocharger specialist ABB Turbo Systems is the innovative UniAir fully-variable valve control system which has been developed to volume production readiness by Schaeffler. ABB will contribute its know-how of efficient, single and two-stage turbocharger technology, as well as marketing and sales for large, high-performance engines. The cooperation applies to units with a performance above 400 kW (544 PS) per cylinder. The applications of these large engines are in marine, machine and stationary operation.
"The fully-variable valve control system (VVT) is the perfect match for our modern high-pressure- and two-stage turbocharging systems", explains Oliver Riemenschneider, head of sales and marketing, ABB Turbo Systems. The advantages of the VVT system in conjunction with high-pressure turbocharging are both in the fields of emission and fuel consumption reduction and in the improvement of the start, part-load and acceleration behavior. The UniAir fully-variable, hydraulic valve control system is behind the VVT system. It enables the variation of both valve timing and valve lift.
"The cooperation with ABB Turbo Systems will open up new areas of application for the innovative valve control system", explains Dr. Peter Pleus, who is responsible for motor systems and president of Schaeffler Group Automotive.
