Catalytic converters, which are typically used in exhaust emission control devices, convert toxic combustion products and carbon monoxide from an internal combustion engine back into less toxic substances. This is done through a series of chemical reaction. These reactions occur when a specific combination of catalytic agent, often one or several, is introduced to the engine. HETAC (High Efficiency Transifier Catalytic Converter) is the most common catalytic agent. It is an exhaust gas treatment device for heavy-duty engines. The catalytic convert includes many parts, including the catalytic conversion housing, the catalytic assembly, the catalyst and the cleaning chamber.
Both the passive and active catalytic conversions have their benefits and drawbacks. For active catalytic conversions to work, they require an active part and a spark plug. This makes them susceptible to “time fading”, which is the gradual loss of performance caused by constant triggering. Passive catalytic converters (such as those found in gas engines) do not require spark plugs and don’t degrade over time.
Catalytic convertors must meet various emission standards set forth in different states and national jurisdictions. This means you, as a car purchaser, need to be aware about the type of catalytic conversion you are considering. It is a good choice to buy a converter approved by the EPA to ensure maximum protection and to choose a cost-effective one that meets all your needs. It is strongly recommended that before you purchase your converter, you review the applicable regulations at your vehicle’s place.
Catalytic convertors are used to reduce the levels of nitrogen oxides (hydrocarbons) and carbon dioxide in your vehicle’s exhaust. These gases can cause the catalyst to be inactivated, which causes premature dissipation. Ozone gas, a reactive gas with nitrogen oxides, dissolves quickly in the exhaust stream. Carbon dioxide is another highly reactive gas. It quickly reacts to oxygen in the exhaust stream and forms carbon monoxide. This can be dangerous and deadly if not properly ventilated.
Catalytic converters work with platinum and palladium inlet or outlet tubes. In order for your catalytic converter to be effective, both platinum and palladium must be present in pristine condition. Platinum and palladium can be difficult to obtain in pure form because they are delicate metals. They are also expensive and can be difficult after fabrication. As a result, most catalytic converters are fabricated from steel mesh, which is a comparatively inexpensive substitute for platinum and palladium.
When you look under an automobile’s hood, you will see that the catalytic converter assembly consists primarily of a metal sleeve connected to the engine’s exhaust manifold. The sleeve is made up of steel strands that are wrapped around a mandrel that forms the back of the catalytic converter. Metals such as steel and aluminum are combined to form an overall alloy that has high electrical and mechanical properties. The final product is an outer metal sleeve that connects the back of this sleeve with the rest of the converter. The entire assembly is then joined to create a complete catalytic conversion.
Diesel engines commonly use catalytic convertors to reduce carbon monoxide levels in the exhaust manifold. Catalytic converters utilize a two-step process: first, the catalyst is inlet; second, the catalyst is discharge. The catalyst must be inlet as well as discharge simultaneously to be effective. The catalyst must be inlet first and then discharged. Metal oxides are formed when the catalyst is inlet and discharged simultaneously. Catalyst inlet ports are usually located near the muffler, and the engine intake. When an individual uses their vehicle these ports release carbon Monoxide into the atmosphere.
Catalytic converters have many benefits to them; they produce excellent exhaust gas, lower emissions, and require very little maintenance. They have also been found to significantly reduce noise pollution caused by most gasoline-powered vehicles. They are more popular than other options due to their excellent exhaust gas quality, low emissions, and lack of tuning or maintenance. Converters are widely used in diesel-powered vehicles, gasoline-powered vehicles, and hybrid automobiles.
