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.
Three-way catalytic converters, which have been very effective at reducing NO x in petrol engine exhaust, do not function well for them. [53] [54] As NO x are harmful air pollutants, regulators in the United States and Europe have implemented increasingly stringent NO x emission standards for passenger cars since the early 2000s. [55] [54]
[11] [14] The codes on catalytic converters identify the make, model and place of origin of catalytic converters, which in turn identify their value, due to variation in state emission laws. [ 11 ] [ 18 ] As an example, GD3 EA6 denotes a Toyota Prius manufactured between 2004 and 2009; [ 11 ] [ 14 ] at the peak of the PRP metal prices, its high ...

The 1999–2003 trucks also had a deadhead fuel system and a "long lead" injector in cyl. number 8 due to lower fuel pressures with the deadhead design (AE code injector). The California trucks from 1996 and 1997 have a 120 cc (7.3 cu in) split-shot fuel injectors; other trucks did not get split-shot injectors until 1999.
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.
x) without a catalytic converter. Hydrocarbons (unburnt fuels and oils) and carbon monoxide emissions still require treatment to meet automobile emissions control regulations. Recent research has shown that the hybrid fuels combining different reactivities (such as gasoline and diesel) can help in controlling HCCI ignition and burn rates.
A catalytic heater is a flameless heater which relies on catalyzed chemical reactions to break down molecules and produce calefaction (heat). [1] When the catalyst, fuel (e.g., natural gas), and oxygen combine together, they react at a low enough temperature that a flame is not produced.
