Catalytic converter

A catalytic converter is an exhaust emission control device that reduces toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction (redox reaction). Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and.

How a Three Way Catalytic Converter Works

 · The three way catalytic converter came into frequent use in the s because it had a distinct advantage over its predecessor, the two way catalytic converter. Nonetheless, the function of a 3 way catalytic converter begins with the essential functions of its two way cousin. A two way catalytic converter focuses on converting carbon monoxide.

Catalytic Converter

Most modern cars are equipped with three-way catalytic converters. "Three-way" refers to the three regulated emissions it helps to reduce -- carbon monoxide, VOCs (volatile organic compounds), and NOx (the various nitrogen oxides) molecules. The converter uses two different types of catalysts, a reduction catalyst and an oxidization catalyst.

3 Way Catalytic Converters Three Way Catalytic Converter

Three-way: A 3 way converter does the same as a two-way, but also reduces nitrogen oxides to nitrogen. Three-way plus: Also referred to as a "dual-bed" converter, a three-way plus converter includes an air supply to increase oxygen levels. However, these converters are rarely used as they are not as efficient as current three-way converters.

3-Way Catalytic Converters. Nett Technologies' 3-Way Catalytic Converters control exhaust emissions from stoichiometric CNG, LPG and gasoline engines. 3-Way Catalytic Converter technology cannot be used on lean-burn CNG or diesel engines (see SCR for diesel NOx control). 3-Way Catalytic Mufflers are the most effective way of controlling Carbon Monoxide (CO), Hydrocarbons (HC), and Nitrogen.

 · The activity of the catalytic converter is expected to be greatly dependent on the operating age. In order to elucidate the operating age with respect to CH 4 emission, two three-way catalytic converters were employed in these experiments. They were a fresh catalytic converter (TC-A ) and a catalytic converter with 78,000 km of use (TC-B).

Although mathematical modeling of catalytic converters is more than 20 years old, the complexities of real world three-way catalyst operation have been only recently addressed (Oh, , Montreuil et al., Pattas et al., ;Siemund et al., ;Koltsakis et al., a).

Catalytic Converter FAQ

Normal operating temperatures of a converter are 500-800°F, and up to °F when the vehicle is under heavy load. To melt the catalytic converter's substrate, the temperature inside the converter would have to exceed °F. Q: Will replacing my converter with a new one eliminate the P/P code from coming on?.
