A catalytic converter is a device invented by Eugene Houdry to decrease the toxicity of emissions from an automobiles internal combustion engine. He was a French mechanical engineer who lived in the Los Angeles area in the 1950s and his expertise also included catalytic oil refining. His goal was to decrease air pollution. In 1975, the government passed laws that required US car makers to make refinements to car engines and fuel systems which included the catalytic converter. This simple device converts pollutants that are harmful into harmless emissions before leaving the car’s exhaust system. Research has proven that catalytic converters decrease carbon monoxide by 85%, hydrocarbon emissions by 87%, and nitrous oxide by 62% for the life of the vehicle. In 1985, the U.S. Environmental Protection Agency confirmed that catalytic converters saved health costs. evolved to recycle used converters when they were damaged or just worn out. This simple device has a big impact by converting harmful pollutants to safe emissions before leaving the car’s exhaust system. However, catalytic converters do go out and need to be replaced. Your old converter has value and can be sold to companies that specialize in recycling catalytic converters. Precious metals can be extracted such as platinum, palladium, and rhodium.
