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 particular combination of catalytic ingredients, often one or two, is introduced into 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 active and passive catalytic converters have their 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. On the other hand, passive catalytic converters, such as those found in gas engines, do not require a spark plug and do not degrade over 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 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. It is strongly recommended that before you purchase your converter, you review the applicable regulations at your vehicle’s place.
The purpose of catalytic converters is to reduce the amount of nitrogen oxides, hydrocarbons, and carbon dioxide in the exhaust from your vehicle. These gases can have the effect to inactivate the catalytic converters and lead to premature dissipation. Ozone gas is a highly reactive gas that reacts with nitrogen oxides. It quickly dissolves into the exhaust stream. Carbon dioxide is likewise highly reactive and quickly combines with oxygen in the exhaust stream to form carbon monoxide, a highly toxic gas that can be deadly without proper ventilation.
Catalytic converters are made to work with platinum, palladium outlet tubes and inlet tubes. Your catalytic converter must work in perfect condition to ensure its effectiveness. Platinum and palladium, which are delicate metals, are difficult to find in their pure form. They are also very costly and can often be difficult to recover from fabrication. Most catalytic converters are made from steel mesh, which can be used as a 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. Combine metals such as aluminum and steel to create an alloy with high mechanical and electrical properties. The final product consists of an inner metal sleeves that connect the back of the sleeve and the rest of your converter. This entire assembly then links together to form a complete catalytic converter.
Catalytic converters are used in diesel engines to reduce carbon monoxide emissions. Catalytic converters utilize a two-step process: first, the catalyst is inlet; second, the catalyst is discharge. The catalyst must be simultaneously inlet/discharge to ensure it is effective. 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.
They have many advantages: they produce excellent exhaust gases, emit lower levels of emissions, and require little maintenance. They have been shown to reduce noise pollution from most gasoline-powered automobiles. They produce excellent exhaust gas and produce minimal emissions. They also don’t require tuning, maintenance or rebuilding. They are used in hybrid cars, diesel-powered vehicles, and gasoline-powered vehicles.
