Reduce emissions with exact stops and starts

Stop Start
The automotive industry is constantly finding ways of reducing CO2 emissions, and developing more energy efficient vehicles. One is the stop-start functionality, where the engine automatically stops at traffic lights, queues or stop signs and is instantly re-started at green light.

SKF engineer Susanne Blokland and her SKF team have made a key contribution to this technology; the SKF Rotor Positioning Bearing. A magnetic field from this bearing provides the engine control system with the rotor’s exact angular position, thus  enabling the engine to be conveniently re-started.

The bottom line is significantly reduced CO2 emissions. Up to 30 percent in heavy city traffic. And fuel consumption may be cut proportionally. It’s another great example of knowledge engineering at work.
