Catalytic converters are exhaust emission control devices that convert toxic combustion by-products from internal combustion engines to less toxic substances. This is done by catalyzing chemical reactions. These reactions occur when a particular combination of catalytic ingredients, often one or two, is introduced into the engine. HETAC (High Efficiency Transifier), a catalytic device for heavy duty engines, is the most widely used. There are many parts to a catalytic device, including the housing, catalytic connector assembly, catalyst cleaning chamber, and the catalyst.
Both active and passive catalytic convertors have their pros and cons. An active and passive catalytic convertors require a sparkplug to start the reaction. This makes them more susceptible to “timesoftening”, a gradual deterioration in performance caused over time 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. As a car buyer, you should be aware of the type of catalytic converter that you are considering for your vehicle. It is a good idea not only to get the best protection for your vehicle but also to make sure you are getting a reasonable one that suits your needs. If you are unsure about this information, it is strongly suggested that you consult the regulations for your vehicle’s operation before purchasing your converter.
Catalytic converters reduce the amount of carbon dioxide, hydrocarbons, or nitrogen oxides in the exhaust of your vehicle. These gases have the effect of inactivating catalysts, which can lead to premature dissipation. Ozone gas, a reactive gas with nitrogen oxides, dissolves quickly in the exhaust stream. Carbon dioxide is also highly reactive and reacts quickly with oxygen in exhaust stream to form carbon monoxide. This toxic gas can be deadly if it is not ventilated properly.
Catalytic convertors can work with either platinum or palladium outlets and inlet tubes. To make your catalytic convertor work, you must have both platinum and palladium in pristine condition. Platinum and palladium, which are delicate metals, are difficult to find in their pure form. They are also expensive and can be difficult after fabrication. Most catalytic converters are made from steel mesh, which can be used as a substitute for platinum and palladium.
When you look at catalytic conversions under the hood of an auto, you’ll see that the converter assembly is composed of a sleeve made of metal that connects to the exhaust manifold. The sleeve consists of steel strands that are wrapped around the mandrel that forms back of the catalytic conversion. Combining metals such steel and aluminum to make an alloy that has high mechanical and electrical properties is possible. The final product is an inner metal sleeve, which connects the back of the sleeve to 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 conversions follow a two-step method: first, the catalyst has to be inlet, then the catalyst has to be discharged. The catalyst must be inlet as well as discharge simultaneously to be effective. Metal oxides are formed as a result of the catalyst being inlet and then discharge; catalyst inlet ports are typically located near the muffler and the engine intake port. These ports allow carbon monoxide to be released into the atmosphere when an individual uses their vehicle.
Catalytic convertors have many advantages. They produce excellent exhaust gases and emit very low levels of carbon dioxide. They have been shown to reduce noise pollution from most gasoline-powered automobiles. Many people prefer them over other options because they produce excellent exhaust gas, produce minimal emissions, and do not require tuning, maintenance, or rebuilding. Convertors are commonly used in gasoline-powered cars, hybrid cars, and diesel-powered vehicles.
