Top Facts On Do All Cars Have Catalytic Converters?
Catalytic converters were first widely introduced on cars in the United States after the 1970 Clean Air Act set legal limits on vehicle emissions.
Modern three-way catalytic converters can convert over 90% of hydrocarbon, carbon monoxide and nitrogen oxide emissions into less harmful compounds.
All gasoline and diesel passenger vehicles sold in the US since the 1980s have been required by law to have catalytic converters equipped.
Electric vehicles do not require catalytic converters because they have no internal combustion engine generating emissions.
Catalytic converters contain precious metals like platinum, palladium and rhodium to serve as catalysts in the chemical conversion of pollutants.
Stolen catalytic converters can fetch over $100 for the precious metals at scrapyards, making some vehicles targets for theft.
Malfunctioning converters lead to increased air pollution, reduced fuel economy, engine issues and failure of emissions testing inspections.
Modern catalytic converters are designed to last over 100,000 miles under normal driving conditions before needing replacement.
Diesel vehicles have specialized diesel oxidation catalysts and NOx reduction systems rather than the typical gasoline catalytic converters.
Removing or disabling a catalytic converter on a registered vehicle violates environmental regulations and is illegal in many regions.
