  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. Cerium(III) oxide - Wikipedia

    en.wikipedia.org/wiki/Cerium(III)_oxide

    It is used in catalytic converters ("three-way catalytic converter") for the minimisation of CO emissions in the exhaust gases from motor vehicles. When there is a shortage of oxygen, cerium(IV) oxide is oxidizes carbon monoxide to the benign dioxide: [ 3 ] [ 4 ]

  4. Catalytic heater - Wikipedia

    en.wikipedia.org/wiki/Catalytic_heater

    The catalytic heater is contained within the package which is usually made out of stainless steel. Instrument gas and pilot preheating regulators are only used for freeze protection, and to heat up the gas before it reaches the pilot. It can also be used to heat a stream of gas that is used for measurement or instrumentation. Space heating is a ...

  5. 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.

  6. Top Tier Detergent Gasoline - Wikipedia

    In 2004 representatives of BMW, General Motors, Honda, and Toyota got together to specify what makes a good fuel. Using recommendations from the Worldwide Fuel Charter, a global committee of automakers and engine manufacturers, they established a proprietary standard for a class of gasoline called "TOP TIER" Detergent Gasoline The new standard ...

  7. Monolith (catalyst support) - Wikipedia

    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.

  8. John J. Mooney - Wikipedia

    en.wikipedia.org/wiki/John_J._Mooney

    Mooney was awarded a total of 17 patents, the latest being one for a catalytic converter for the small two-stroke engines, used in chainsaws, lawn mowers, and leaf blowers. His invention reduced hydrocarbon emissions by as much as 70%, improved fuel efficiency and added up to 40% more power while addressing the pollution of an engine that often ...

  9. Emission standard - Wikipedia

    en.wikipedia.org/wiki/Emission_standard

    The ECE 15/05 norms (also known as the Luxemburg accord, strict enough to essentially require catalytic converters) began taking effect gradually: the initial step applied to cars of over 2000 cc in two stages, in October 1988 and October 1989. [2] There followed cars between 1.4 and 2.0 liters, in October 1991 and then October 1993.
