  2. Catalytic converter - Wikipedia

    en.wikipedia.org/wiki/Catalytic_converter

    A three-way catalytic converter on a gasoline-powered 1996 Dodge Ram Simulation of flow inside a catalytic converter. A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction.

  3. Top Tier Detergent Gasoline - Wikipedia

    en.wikipedia.org/wiki/Top_Tier_Detergent_Gasoline

    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. Also, if too much is used, the additive may cling to valve stems and cause them to hang open. [5] Most mechanics agree that consistent use of a fuel with adequate cleaning ability is best [citation ...

  4. Selective catalytic reduction - Wikipedia

    en.wikipedia.org/wiki/Selective_catalytic_reduction

    Commercial selective catalytic reduction systems are typically found on large utility boilers, industrial boilers, and municipal solid waste boilers and have been shown to lower NO x emissions by 70-95%. [1] Applications include diesel engines, such as those found on large ships, diesel locomotives, gas turbines, and automobiles.

    Carl D. Keith (left) and John J. Mooney at the award ceremony for the National Medal of Technology and Innovation for the invention, application and commercialization of the three-way catalytic converter (2003) The 1970 amendments to the Clean Air Act required significant reductions in hydrocarbon, carbon monoxide and nitrogen oxide emissions.

  6. Exhaust system - Wikipedia

    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.

  7. Diesel exhaust fluid - Wikipedia

    en.wikipedia.org/wiki/Diesel_exhaust_fluid

    x level in the exhaust gas (before catalytic converter, after catalytic converter, and possibly between catalytic converters if there is more than one), current ammonia filling level, [11] engine operating temperature and speed. [12]

  8. 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.

  9. Secondary air injection - Wikipedia

    en.wikipedia.org/wiki/Secondary_air_injection

    A sensitive reed valve assembly called the aspirator valve is placed in the air injection pumping, which draws its air directly from the clean side of the air filter. During engine idle, brief but periodic negative pressure pulses in the exhaust system draw air through the aspirator valve and into the exhaust stream at the catalytic converter.
