The actual introduction of catalytic converters was 1973 and of course development work before that. From our handy Wikipedia: Widespread adoption of catalytic converters didn't occur until more stringent emission control regulations forced the removal of the anti-knock agent tetraethyllead , from most gasoline, because lead was a 'catalyst poison' and would deactivate the converter by forming a coating on the catalyst's surface, effectively disabling it. [9] Catalytic converters were further developed by a series of engineers including John J. Mooney and Carl D. Keith at the Engelhard Corporation , [10] creating the first production catalytic converter in 1973. [11] legislation.govt.nz Imagine trying to get something changed.
