    en.wikipedia.org/wiki/Exhaust_system

    There is a light-off temperature from which catalytic converters start to be efficient and work properly. [7] Catalytic converters can cause back pressure if clogged or not designed for the required flow rate. In these situations, upgrading or removal of the catalytic converter can increase power at high revs.

    And General Motors fuels engineer Andrew Buczynsky says the various engine-cleaning additives available at auto-parts stores should be used with caution. He said some work but most do not, and that care must be taken when using these additives because some may contaminate the catalytic converter.

    en.wikipedia.org/wiki/Monolith_(catalyst_support)

    Monolithic catalyst supports are extruded structures that are the core of many catalytic converters, [1] most diesel particulate filters, and some catalytic reactors. Most catalytic converters are used for vehicle emissions control. Stationary catalytic converters can reduce air pollution from fossil fuel power stations.

  7. Catalyst poisoning - Wikipedia

    en.wikipedia.org/wiki/Catalyst_poisoning

    In catalytic converters used on automobiles, the combustion of leaded gasoline produces elemental lead, lead(II) oxide, lead(II) chloride, and lead(II) bromide. Lead alloys with the metals present in the catalyst, while lead oxides and halides coat the catalyst's surfaces, reducing the converter's ability to reduce NOx emissions.

  8. Secondary air injection - Wikipedia

    en.wikipedia.org/wiki/Secondary_air_injection

    When the catalytic converter is cold, air injected at the upstream point burns with the deliberately rich exhaust so as to bring the catalyst up to operating temperature quickly. Once the catalyst is warm, air is injected to the downstream location — the catalytic converter itself — to assist with catalysis of unburned hydrocarbons.
