The initial catalytic converters were installed in cars in the 1975 model year. In 1976, the three-way catalyst was introduced, which, after updates, has been able to eliminate 97% of tailpipe hydrocarbon emissions, 96% of carbon monoxide and 90% of nitrogen oxides produced in automobile engines and those used in light trucks and sport utility ...
He built a generic catalytic converter capable of reducing carbon monoxide and unburned hydrocarbons from automobile exhausts. For his design, he received U.S. Patent 2,742,437 in 1956. [ 2 ] [ 13 ] [ 32 ] Catalytic converters eventually became standard equipment in American cars, following passage of the Clean Air Act , introduced by Edmund S ...
Car manufacturers and catalyst companies were trying to develop a multiple step process that would address hydrocarbons and carbon monoxide in one process while reducing nitrogen oxides in another. [1] Chemist Carl D. Keith and Mooney with their team at Engelhard came up with the first production catalytic converter in 1973. The three-way ...
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.
Claudette Hill was one of many L.A. car owners who had their catalytic converters stolen during a rash of thefts in 2020. Right away, the retired seamstress got the auto part replaced.
The Maruti Suzuki had never been equipped with seat belts until exports began, meaning that such parts originally had to be imported from Japan to be fitted to export market cars, as with everything relating to building left-hand-drive cars. [5] The Maruti also got its first catalytic converter to meet European requirements.
