Abstract
Engine efficiency and environmental issues have increased the need for high performance engine parts. Of significant importance is the moving mass of the valve train components. Lower masses reduce inertia and this reduces friction losses. New technology inquiries from customers, market competition, possible weight reductions of 20-50%, and the ability to withstand increased operating temperatures by 100-150°C, have increased the need to develop high performance automotive engine valves at competitive costs. Lightweight hollow valves could be mentioned as one of the major targets for the development work. Achieved goals can directly be translated into lower engine working temperature or higher compression ratios for conventional engines. Also, there is a close cooperation between TRW's development and design teams of the lightweight valve project and the electromagnetic valve actuation programs (EMVA).
