A catalytic converter is an exhaust emission control device that converts harmful pollutants and contaminants in an internal combustion automobile engine to less harmful gases by catalyzing an acid-redox reaction. In an internal combustion engine, a catalyst is used to convert harmful pollutants and contaminants in exhaust from the combustion of the internal combustion fuel engine. The catalytic converter inside an engine mixes oxygen and the hydrogen in a converter, which is then able to react with harmful contaminants and pollutants that are in the exhaust. The resultant reaction causes the engine exhaust to be clean of dangerous nitric oxide. It also reduces carbon monoxide and other noxious emissions.
There are a variety of catalytic convertors on the market. Each has distinct design function, purpose, and usage. Each converter has four main components which are the catalytic converter (the catalyst) and the drain and the catalytic barrier. The catalyst is the primary ingredient in the converter. It is typically a metal such as beryllium, titanium, or chrome. The catalyst made of metal is honeycomb structure that permits the metal parts to connect and interact with one another.
Common catalytic converters have the bowls and channels that are filled with an inert gas like nitrogen or an inertgas that has a high boiling temperature like graphite. Different catalytic converters feature an outer shell that has channels that run along the sides and edges of the bowl. Some also contain another electrode, which creates an electric field that interacts with exhaust gases. The two electrodes create an electric current that burns the pollutants away.
Some catalytic converters have a single drain and an outer edge. Some converters have three drains and an outer edge. These catalytic converters with an inner edge mean that there are only two drain channels. They do not interact with one another. If they are located at an angle, the drain channels will interact with one another. For instance when both drain channels were set at a thirty degree angle, the current generated would be greater than necessary.
The most common metal used in the manufacture of catalytic converters is platinum. Iron, rhodium, and platinum are also popular metals. The platinum metal must be coated with catalyst material in order to catalyze effectively. Rhodium is the primary catalyst used in platinum-coated catalytic converters. Many vehicles in the United States and other countries still make use of platinum-coated catalytic converters.
There are other parts of a vehicle that can be replaced when the engine starts to fail. If you catalyzed the engine, it could be a significant expense. If your vehicle is having trouble starting, it is recommended to take it to a mechanic immediately. Catalytic converters can prevent the engine from operating completely. This is often caused by an unintentional theft of a catalytic converter.
All metals, including platinum, aren’t at risk of theft. Certain platinum-coated catalytic converters have failed due to theft of platinum. It has been reported that platinum-coated parts have failed multiple times, even when the catalytic converter was intact. Other parts that have failed include the timing belt, timing pulley, main bearing and main valve cover and the timing chain.
Catalytic converters can also fail due to oxides of metal, especially lead. A catalyst that has an oxygen bond is an example of a catalytic converter. The catalyst absorbs oxygen, and converts it into heat. The heat that is accumulating in an engine exhaust stream because of the catalytic converters is known as exhaust gas oxidation. Catalytic converters that do not meet the automotive standards are frequently substituted with a new.
