Top Facts On Do All Cars Have Catalytic Converters?

Fact 1

Catalytic converters were first widely introduced on cars in the United States after the 1970 Clean Air Act set legal limits on vehicle emissions.

Fact 2

Modern three-way catalytic converters can convert over 90% of hydrocarbon, carbon monoxide and nitrogen oxide emissions into less harmful compounds.

Fact 3

All gasoline and diesel passenger vehicles sold in the US since the 1980s have been required by law to have catalytic converters equipped.

Fact 4

Electric vehicles do not require catalytic converters because they have no internal combustion engine generating emissions.

Fact 5

Catalytic converters contain precious metals like platinum, palladium and rhodium to serve as catalysts in the chemical conversion of pollutants.

Fact 6

Stolen catalytic converters can fetch over $100 for the precious metals at scrapyards, making some vehicles targets for theft.

Fact 7

Malfunctioning converters lead to increased air pollution, reduced fuel economy, engine issues and failure of emissions testing inspections.

Fact 8

Modern catalytic converters are designed to last over 100,000 miles under normal driving conditions before needing replacement.

Fact 9

Diesel vehicles have specialized diesel oxidation catalysts and NOx reduction systems rather than the typical gasoline catalytic converters.

Fact 10

Removing or disabling a catalytic converter on a registered vehicle violates environmental regulations and is illegal in many regions.
