An integral part of vehicle emission control systems since 1975. Oxidizing converters remove hydrocarbons and carbon monoxide (CO) from exhaust gases, while reducing converters control nitrogen oxide (NOx) emissions.

Catalytic converters have been required equipment on all new motor vehicles sold in California since 1979. California Ambient Air Quality Standards (CAAQS): Standards set by the State of California for the maximum levels of air pollutants that can exist in the outdoor air without unacceptable effects on human health or the public welfare. These are more stringent than NAAQS.
A part of a passenger cars exhaust pollution control that super heats exhaust fumes, turning them into inert gases. This device can be extremely hot and is located under the car body in the undercarriage area.
A device incorporated in the exhaust system which speeds up the natural decomposition of the exhaust gases, and reduces the amount of harmful gases released into the atmosphere. Cars fitted with catalytic converters must be operated on unleaded petrol, as leaded petrol will destroy the catalyst.
A canister attached to a car's exhaust system containing a catalyst that achieves the speedy conversion of noxious exhaust gases into less harmful ones. Because the catalyst is "poisoned" by the presence of lead, the mandatory fitment of catalytic converters in 1986 also meant new cars needed to run on unleaded fuel.

A catalytic converter reduces the amount of pollutants in your vehicle's exhaust by causing a chemical reaction that transforms once harmful particles into more benign elements. It looks like a muffler, and is filled with platinum and palladium infused ceramics, the catalyst for the transformation.
All engines, diesel, gasoline, propane and natural gas, produce exhausts containing carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx), from the in-complete combustion of engine fuel. Diesel engines also emit a particulate matter (DPM). All (4) pollutants are recognized by EPA and CARB, as serious potential health hazards. These pollutants can be substantially reduced by the addition of a catalytic converter, installed in the engine's exhaust outlet.

The proper name for what is often known as a catalyst or sometimes just a cat. This is a device fitted to the exhaust and used for making the exhaust gases less harmful to the environment. It accomplishes this task by a process of chemical reactions that change the properties of the emissions but not the converter itself - hence it is a catalyst.

A catalytic converter (colloquially, "cat" or "catcon") is a device used to reduce the toxicity of emissions from an internal combustion engine. First widely introduced on series-production automobiles in the US market for the 1975 model year to comply with tightening EPA regulations on auto exhaust, catalytic converters are still most commonly used in motor vehicle exhaust systems. Catalytic converters are also used on generator sets, forklifts, mining equipment, trucks, buses, trains, and other engine-equipped machines.
