2007 Daihatsu D-Compact Wagon

Using nanotechnology, Daihatsu has succeeded in implanting palladium as ions into a special perovskite ceramic crystal. The palladium ions come out of and go back into the perovskite crystal in response to the natural changes in the exhaust-gas conditions. When the exhaust gas is at the reduction stage (with too little oxygen), palladium ions come out of the perovskite crystal and become active metallic particles. When the exhaust gas is at the oxidation stage (with too much oxygen), the palladium particles go back into the crystal and return to their original state. By repeating this selfregeneration cycle, the Intelligent Catalyst can maintain its initial, excellent emission cleaning capability over a long time, dramatically reducing the use of precious metals, which are valuable natural resources, and at the same time achieving much cleaner emissions.

(Ed.'s note: replace "Using nanotechnology" with "Using the science of the nanoscale" and it reads hype-free.)
