Nevertheless, some vehicle owners remove or "gut" the catalytic converter on their vehicle. [30] [31] In such cases, the converter may be replaced by a welded-in section of ordinary pipe or a flanged "test pipe", ostensibly meant to check if the converter is clogged by comparing how the engine runs with and without the converter. This ...
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.
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.
When the catalytic converter is cold, air injected at the upstream point burns with the deliberately rich exhaust so as to bring the catalyst up to operating temperature quickly. Once the catalyst is warm, air is injected to the downstream location — the catalytic converter itself — to assist with catalysis of unburned hydrocarbons .
When Ken Shay, a longtime Chicago resident, went out to start his 2013 Lexus RX 350 SUV parked near his Lincoln Park apartment on a recent weekday morning, he was in for a rude awakening. His ...

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.
To lose your catalytic converter these days is to be a temporary supplier to a large, well-financed underground enterprise. Dude, where’s my catalytic converter? Probably back in the supply chain
