WINNER: System adds power, cuts emissions

Schaeffler Technologies AG
What: UniAir fully variable valve lift system
Innovation: Schaeffler replaced a fixed mechanical valve lift system with a variable one that uses oil pressure to actuate the valve. The timing of the oil pressure is controlled by a high-speed solenoid, allowing the engine controls to vary the amount of air in the combustion mix, adding power and torque and reducing emissions and fuel consumption. Fiat calls its version of the system MultiAir.
First customer: Fiat S.p.A., for the Alfa Romeo MiTo, September 2009
