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 happen when a certain combination of catalytic agents, often one or more, are introduced into the engine. The most commonly used catalytic agents are HETAC (High-Efficiency Transifier) catalytic converters, an exhaust gas treatment device for heavy duty engines, and TET (Thioglycolate) catalytic converter. The catalytic converter includes many parts, including but not limited to the catalytic converter housing, the catalytic converter assembly, the catalyst, and the catalyst cleaning chamber.
Both active and passive catalysts have their strengths and weaknesses. To initiate the reaction, active catalytic converters require a spark plug and an activate part. This makes them vulnerable to “time-softening”, which is the gradual decrease in performance over time caused by constant activation of the catalytic convert. 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. This information should be reviewed by you before purchasing your converter.
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 is a highly reactive gas that reacts with nitrogen oxides. It 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 made to work with platinum, palladium outlet tubes and inlet tubes. For your catalytic converters to work properly, both platinum or palladium must be in pristine condition. Unfortunately, platinum and palladium are extremely delicate metals and are very difficult to obtain in pure forms. Additionally, they are extremely expensive and often difficult to recover after fabrication. Steel mesh is a cheaper substitute for platinum, palladium, and most catalytic convertors are made of it.
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. Combining metals such steel and aluminum to make an alloy that has high mechanical and electrical properties is possible. The final product is an outer metal sleeve that connects the back of this sleeve with the rest of the converter. The whole assembly then connects together to form a complete catalyst converter.
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. Inlet and discharge must occur simultaneously in order for the catalyst’s effectiveness. The catalyst’s inlet and discharge simultaneously creates metal oxides. Most catalyst inlet ports can be found near the muffler or the engine intake port. These ports release carbon monoxide into the air when an individual uses their vehicle.
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. 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.
