Ceramic Fact Sheets : Ceramic Applications in Automobiles Description Engine designers are always looking for alternative designs to lower cost and emissions and increase fuel economy and performance. Often the improved designs require material substitutions. Ceramics, with their unique heat, wear, and corrosion resistance; light weight; and electrical and heat insulation; may be the enabling technology for many critical components in engines of the future. Ceramics have been important in automobiles from the beginning, in spark plug insulators and glass windows (early 1920s). Virtually all catalytic converters in modern automobiles have ceramic supports for the catalyst, which has been instrumental in reducing automobile emissions. Most modern cars also use ceramic oxygen sensors in concert with computer controls to optimize combustion and reduce emissions. Computer controls and electronic components in automobiles use a large number of ceramic substrates and packages, which are critical to the performance of the devices. Also, numerous electrical motors are used in modern cars for automated adjustment of seats, windows, etc. Ceramic magnets are used in many of these motors. Recently, ceramic components have been introduced in fuel systems and valve trains of heavy-duty diesel engines. Cars of the future may have ceramics in internal components, such as valves and valve seats, and in wear-resistant applications in fuel systems and valve trains. Futuristic cars may also use ceramic fuel cells for near-emission-free engines. acers.org ... original link with a list of individuals that may be contacted regarding ceramic applications in automobiles. PSSST ... ya wanna see a 'ceramic' fuel cell that BMW just recently installed ... follow the next pdf link ... netl.doe.gov ... Global Thermoelectric supplied the fuel cell stacks pg.9, and the charts for "Single Power Density with Hydrogen" and "Load Profile Test" on pages 11 & 12 were achieved with excellent results by Global's SOFC Team.
