Excerpt

The thermal load of valves in combustion engines continues to increase. Most of the heat flowing from the valve into the cylinder head passes through valve seats and guides. New materials and product developments with high thermal conductivity show considerable potential for reducing the temperatures of valves. As a study by Federal-Mogul reveals, this can be used in many ways to lower component load, improve combustion and reduce emissions when designing viable future powertrains. …
