A catalytic converter is an important component of your car’s exhaust system. It uses complex chemical reactions to convert toxic pollutants in your car exhaust to less dangerous chemicals. There are a number of different types of catalytic converters; here’s a quick guide.
Two-Way
A two-way catalytic converter is one of the simplest kinds. As the name suggests, it has two major roles. The first one is to capture carbon monoxide, which is a poisonous byproduct created by the burning of gasoline, and change it into carbon dioxide. The second is to capture any unburned fuel that has escaped the engine and change it into carbon dioxide and water vapor. These are particularly common on classic vehicles produced before 1981, foreign cars, and diesel engines.
Three-Way
Most cars these days are equipped with three-way catalytic converters. This type also handles carbon monoxide and unburned fuel, but it additionally handles a third kind of pollution—nitric oxide, a common precursor to acid rain and smog. A three-way converter breaks it down into nitrogen and oxygen before releasing it from the vehicle.
DOC
Finally, a diesel oxidation catalyst (DOC) is a special type of converter designed to reduce particulate matter created when diesel fuel is burned. To learn more about this and other types of converters, as well as catalytic converter installation in Pacific Beach, check out this link.
