Herkoemmliche technische Materialien erlauben durch Waermeverluste und niedrigeren Wirkungsgrad nicht, Treibstoffenergien bestmoeglich auszunutzen. Die verschiedenen Programme der einzelnen grossen Firmen, den technischen Fortschritt in die eigenen Scheuern zu fahren, werden angesprochen. Besonders erwaehnt werden japanische, europaeische und amerikanische Firmen mit ihren Autoerzeugnissen. Zuverlaessigkeit und Kosten geben den Ausschlag dabei, inwieweit technische Keramik im Motorenbau weiter eingesetzt werde. Fortschritt muesse billig sein.

    For more widespread application, even more emphasis will be placed on cost. It is recommended that R & D programs focus on ways to reduce cost-cost of starting powders, cost of forming and sintering processes through the cost of finish machines and inspection. As a start, the author would be very interested to see a comparison study of the relative cost of ceramic, say silicon nitride, with a common engine metal, say gray cast iron, taking into account mining of the ore, shipping, casting, sintering, machining and inspection. Such a study could help put the cost issue in perspective and be very helpful in guiding and prioritizing R & D programs.
