Multiple cameras on a production line speed the inspection of catalytic converters.

Automobiles use catalytic converters to reduce carbon monoxide, nitrogen oxides, and the hydrocarbons that are produced as a result of fuel combustion and evaporated unburned fuel, thus reducing air pollution. Generally, the converters consist of a ceramic or metal structure coated with a platinum catalyst. To minimize the expensive catalyst components while maximizing the surface area of the converter to the engine exhaust, the converters use a honeycomb structure.
