The extreme valve temperatures experienced on today’s highly boosted downsized engines can lead to reduced valve fatigue life and critical valve guide and stem seal temperatures, resulting in the need for expensive valve steel alloys. The valve guide is the main heat path from the valve stem to the cylinder head.

In general, said Dr. Bernd Bohr, Chairman of the Bosch Automotive Group, the pace of development continues to pick up, in the form of powertrain electrification and the automation of driving. In order to further reduce its CO 2 emissions in this vehicle class, the gasoline engine will require a low-cost, basic hybrid solution.

Fiat Group and Fiat Powertrain Technology introduced their new air management technology Multiair at the Geneva Motor Show. Applied to a turbocharged, downsized engine, MultiAir can contribute to up to a 25% reduction in fuel consumption over conventional naturally aspirated engines with the same performance, according to Fiat.
