The European AGATA programme (Advanced Gas Turbine for Automobiles), is a programme dedicated to the development of three critical ceramic components-a catalytic combustor, a radial turbine wheel and a static heat exchanger-for a 60kW turbogenerator in a hybrid electric vehicle. These three components, which are of critical importance to the achievement of low emissions and high efficiency, have been designed, developed, manufactured and tested as part of a full scale feasibility study. The AGATA partners represent car manufacturers as well as companies and research institutes in the turbine, catalyst and ceramic material fields in both France and Sweden. The AGATA project commenced in early 1993 and has occupied a 5-year period until April 1998. This paper summarises the results from the development of the catalytic combustor, the radial turbine wheel and the static heat exchanger. The catalytic combustor test series have shown NO_x emission levels below 4ppm @ 15% O_2 were obtained when low CO and HC emissions levels were measured at full load conditions and the Mullite Zirconia catalyst substrates have met the AGATA specified operation temperature up to 1350℃. Ceramic Si_3N_4 Turbine have obtained 91000rpm during cold burst speed test and one wheel has survived the proof test speed of 80000rpm, which is the qualification speed for the initial hot test series. Hot spin testing will be performed by ONERA. The plate heat exchanger made by Cordierite ceramics was developed by Ceramiques & Composites, C & C. Tests have shown that the cordierite material meet the AGATA specifications.
