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.
Used catalytic converters can sell for anywhere from $25 to $1,000, depending on the metals content, which varies by a vehicles make and model, according to Scott Vollero and Christopher Gaines ...
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.
Exhaust system backfires occur in engines that have an emission system malfunction, like an air injection system diverter valve problem, an exhaust leak, or when the catalytic converter has been removed. In some high-performance vehicles, when a driver shifts up and lets off the accelerator, the engine has a moment of running rich. This causes ...
It is a U.S. legal requirement to have a catalytic converter. [3] [4] Converters may not be removed from a vehicle that is used only for "off-road" driving in the United States. [5] The main purpose of a catalytic converter on an automobile is to reduce harmful emissions of hydrocarbons, carbon monoxide, and nitrogen oxides into the atmosphere.
The U.S. government's auto safety regulator has ended a 2 1/2-year investigation into Ford engine failures after the company replaced engines or extended the warranty on some vehicles. The ...
The man killed when he was crushed as he attempted to steal a catalytic converter has been identified, the Merced County Coroner’s Office said Wednesday.. Merced police were called about 1:15 a ...
The catalytic converter is a device placed in the exhaust pipe, which converts hydrocarbons, carbon monoxide, and NO x into less harmful gases by using a combination of platinum, palladium and rhodium as catalysts. [16] There are two types of catalytic converter, a two-way and a three-way converter.
