A catalytic converter is usually an exhaust emission control device which converts toxic combustion by-products and carbon monoxide in an internal combustion engine back to less toxic substances by catalyzing a series of chemical reactions. These reactions occur when a specific combination of catalytic agent, often one or several, is introduced to the engine. HETAC catalytic conversions (High-Efficiency Transifier), an exhaust gas treatment device designed for heavy-duty engines, and TET catalytic converters (Thioglycolate), are the most common. Many parts make up the catalytic system, including the housing, the catalytic unit, the catalyst, and cleaning chamber.
Both passive and active catalytic converters each have their own advantages and disadvantages. An active and passive catalytic convertors require a sparkplug to start the reaction. This makes them susceptible to “time fading”, which is the gradual loss of performance caused by constant triggering. Passive catalytic conversions, like those found in gas engines do not require a sparkplug and do not degrade over a period of time.
Catalytic converters must meet emission standards set forth by different national and state jurisdictions. This means that as a car buyer you must know what type of catalytic Converter you are looking at for your vehicle. It is a smart decision to buy a converter that is EPA-approved to protect your vehicle and to be able to afford one that meets your requirements. This information is important to know before you buy your converter.
Catalytic convertors are used to reduce the levels of nitrogen oxides (hydrocarbons) and carbon dioxide in your vehicle’s exhaust. When these gases are emitted, they have the effect of inactivating the catalyst, which leads to the premature dissipation of the resulting gas. Ozone gas, for instance, is highly reactive with nitrogen oxides and quickly dissolves into the exhaust stream. Carbon dioxide is also reactive and quickly reacts with oxygen to form carbon monoxide. Without proper ventilation, this can be a deadly gas.
catalytic converters are designed to work with platinum or palladium inlet and outlet tubes. To make your catalytic convertor work, you must have both platinum and palladium in pristine condition. Unfortunately, platinum and palladium are extremely delicate metals and are very difficult to obtain in pure forms. They are also extremely expensive and difficult to recover once they have been fabricated. Most catalytic converters are made from steel mesh, which can be used as a substitute for platinum and palladium.
You’ll notice that the catalytic convertors are attached to the engine’s exhaust system by a metal sheet. The sleeve is made of steel strands wrapped around a mandrel. This forms the back of the catalytic convertor. 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. This complete assembly then links together to form the catalytic converter.
Diesel engines commonly use catalytic convertors to reduce carbon monoxide levels in the exhaust manifold. Catalytic converters work in two steps: first, the catalyst must be inlet, and second, it must be discharged. To be effective, the catalyst must be both inlet and discharging simultaneously. The catalyst must be inlet and then discharge simultaneously to form metal oxides. Typically, the catalyst inlet ports are located near the engine intake port and the muffler. These ports let carbon monoxide out of the vehicle when it is being used.
Catalytic converters have many benefits to them; they produce excellent exhaust gas, lower emissions, and require very little maintenance. They also significantly reduce the noise pollution generated by most gasoline-powered vehicles. They are preferred by many because they produce excellent exhaust gases, produce minimal emissions, require no tuning, maintenance, or rebuilding, and can be used in a variety of applications. These converters are often used in diesel-powered and gasoline-powered automobiles, as well as hybrid vehicles.
