Exhaust is a natural byproduct of an internal combustion engine used on contemporary vehicles like those from Alfa Romeo and American Motors. It is a necessary evil produced during combustion, but is not exactly impossible to wipe out. One of the low-key Alfa Romeo and American Motors parts that aims to eradicate the vehicle?s exhaust output is the Alfa Romeo catalytic converter. Equipped with chemical catalysts platinum, rhodium, palladium, among others, the catalytic converter oxidizes the exhaust gases of the Alfa Romeo and American Motors before they are emitted into the atmosphere. Catalytic converters are manufactured in two varieties: the ceramic and honeycomb converters, the former being the most-used type among modern vehicles because it incorporates the function of the other and presents new and more effective method of oxidizing the exhaust. In order that exhaust materials are reduced, the car engines of the Alfa Romeo and American Motors primarily control the amount of fuel they burn. They try to keep the air to fuel ratio close to the stoichiometric point, which is the calculated ideal ratio of air to fuel in a burn material. At this ratio, all of the fuel will be burned using all of the oxygen in the air, resulting in less exhaust. For gasoline engines, the stoichiometric ratio is about 14.7:1. This means that for every pound of gasoline, 14.7 pounds of air will be burned. As engine and driving conditions change, this ratio changes as well. Sometimes it will run richer or leaner than the ideal 14.7:1. When the burn mixture falls short or exceeds the ratio, exhausts materials composed of hydrocarbons, nitrogen oxides, and other volatile organic compounds are produced. The engine tries to eliminate these through the chemical reaction produced when the fumes make contact with the catalytic converter. It works in two stages: reduction and oxidation. Reduction is the first stage used by both the Alfa Romeo and American Motors catalytic converter. It uses platinum and rhodium to help reduce the nitrous oxide emissions. When a molecule of these gases contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of oxygen. The nitrogen atoms, on the other hand, bond with other nitrogen atoms that are also stuck to the catalyst. Afterwards, the palladium and platinum metals of the catalytic converter convert the hydrocarbons of unburned gasoline and carbon monoxide to carbon dioxide and water, resulting in exhaust emission that is less harmful.

People buy cars for different purposes and different reasons. The most important quality that a car should possess is it should be driver friendly. Qualities like style, performance and safety come next. But one feature that a car has that sometimes an owner takes for granted is its being environment-friendly.

In different countries around the world, there had been laws formed for car manufacturers to follow when designing a car. Since air pollution is the most common car caused environmental hazard, car owners should always be mindful of the cars they choose not to add to this serious environmental problem.

Cars contribute or do not contribute to air pollution can be traced mainly by having catalytic converters. This part of the internal combustion system is responsible for converting the harmful carbon monoxide into carbon dioxide to be released by the car in its exhaust system.

With this very important function, a car cannot pass for quality checking if it doesn?t have a catalytic converter. Stretching this importance, in 1998 as part of the United States Clean Air act, the United States Environmental Protection Agency required all industries involved in auto repair and other services to not sell after market catalytic converters that have not met EPA standards. The EPA considers the catalytic converters to be the most important pollution control device in a vehicle.

Since the laws regarding pollution control concerning vehicles are passed in the eighties, it affected most car brands existing at that time. Although almost all car manufacturers in the eighties like Honda, Mazda, Nissan, Toyota and their catalytic converters are still easy to find even at this time, there are also few that had already phased out. Some car brands like that of Triumph are now rarely found making it hard for their owners to comply to these laws because their car parts including the Triumph catalytic converter are also hard to find.

Recently, there had been competition for the most environmental friendly car and the new Acura RSX bagged the award. The contenders of the said award were most likely newly manufactured car models, products of the new and modernized technology of the new millennium. These cars are what we commonly see in the streets and their car parts are manufactured almost everywhere. These days, environment-friendly cars are not hard to come by, and it?s a easier to do our share for the environment given the myriad of choices we have.

Believe it or not, automobiles are now manufactured and designed in a way that they are safer both for the user and the environment. The added edge of a vehicle as safer to the environment has been a force driving future growth for automobile makers for decades.

Combustion is never perfect and for that, smaller amounts of more harmful emissions such as Carbon monoxide, Hydrocarbons, and Nitrogen oxides are produced by most care engines. Among the three hazardous elements, Carbon dioxide is believed to contribute much to the severing global warming. These are the three main regulated emissions and also are the ones that catalytic converters are designed to reduce.

The Eastern company of Hyundai Motor Company has risen to the challenge of regulating emissions through the
Hyundai Catalytic Converter. The Korean brand of automobiles believes that the survival of human race, the development of pollution-free vehicles can resolve the dwindling natural resources, and the dream of recovering a cleaner planet. The catalytic converter would allow these end goals. This helpful auto part acts as a reducer and oxidizer for harmful elements a vehicle emits.

For years, there are technology breakthroughs that helped reduced elements like carbon monoxide and hydrocarbons by 96 percent and nitrogen oxides by 75 percent. Cutting-edge technologies like that of the
Mercury Catalytic Converter from Ford Motor Company of the West is one. Aside from the vehicles ability to cut remaining levels of smog-forming emissions, the catalytic converter also does the job well.

At this day and age, more motor companies put their concern about the environment and the environmental effects of their cars and trucks as one of the top priorities. Continuing reductions through the engine make and help from the catalytic converters like that of Hyundai Catalytic Converter and Mercury Catalytic Converter, vehicles nowadays can satisfy customer needs as well as that of the environment.

Pollutants have scattered the globe causing much damage to the ecosystem. One leading soucre of pollution is found in the very air we breath. Most of the time, air pollution is caused by the millions of cars all over the world. That is why automakers have not stopped in developing new technologies that will really help the environment, one of which is producing catalytic converters.

In the case of the VW catalytic converter, it is a device used to reduce the toxicity of emissions from an internal combustion engine. In order to reduce emissions, modern car engines carefully control the amount of fuel they burn. They try to keep the air-to-fuel ratio very close to the calculated ideal ratio of air to fuel called, stoichiometric point. The main emissions of a car engine are nitrogen gas, carbon dioxide and water vapor. These emissions are mostly benign. But because the combustion process is never perfect, some smaller amounts of more harmful emissions are also produced in car engines. These are carbon monoxide, hydrocarbons or volatile organic compounds (VOCs) which is produced mostly from unburned fuel that evaporates. Another harmful compound is nitrogen oxide (NOx), which contributes to smog and acid rain, and also causes irritation to human mucus membranes. These are the three main regulated emissions and also the ones that VW catalytic converters are designed to reduce.

Most modern cars are equipped with three-way catalytic converters. It refers to the three regulated emissions it helps to reduce which are carbon monoxide, VOCs and NOx molecules. The converter uses two different types of catalysts, a reduction catalyst and an oxidation catalyst. Both types consist of a ceramic structure coated with a metal catalyst, which is usually platinum, rhodium or palladium. The idea is to create a structure that exposes the maximum surface area of catalyst to the exhaust stream while also minimizing the amount of catalyst required. There are two main types of structures used in catalytic converters, honeycomb and ceramic beads. Most cars today use a honeycomb structure.

The VW catalytic converter do their job in three stages. The first stage is the reduction catalyst. It uses platinum and rhodium to help reduce the NOx emissions. When a nitrogen oxide molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. The oxidation catalyst is the second stage of the VW catalytic converter. It reduces the unburned hydrocarbons and carbon monoxide by burning them over a platinum and palladium catalyst. This catalyst aids the reaction of the CO and hydrocarbons with the remaining oxygen in the exhaust gas. The final stage is a control system that monitors the exhaust stream and uses this information to control the fuel injection system. There is an oxygen sensor mounted upstream of the VW catalytic converter, meaning it is closer to the engine than the converter is. This sensor tells the engine computer how much oxygen is in the exhaust. The engine computer can increase or decrease the amount of oxygen in the exhaust by adjusting the air-to-fuel ratio. This control scheme allows the engine computer to make sure that the engine is running at close to the stoichiometric point. It also make sure that there is enough oxygen in the exhaust to allow the oxidization catalyst to burn the unburned hydrocarbons and CO.

Today’s technology is also being tapped to help the environment. Like the VW catalytic converters that have proved to be helpful. Since automakers nowadays have realized technology’s limitless potential and their responsibility to the environment, they have also turned to producing hybrid cars.

Car companies are now in a race to becoming the first one to provide environmentally-friendly vehicles to the mainstream in the next few years. This is in response to the common people?s growing need for affordably priced vehicles of this kind. But until these are made available to ordinary car owners, they would have to settle for alternatives in the meantime.

There are a number of alternatives readily available at hundreds of car parts shops. One of the most effective is the catalytic converter. It is a device that works by helping the engine to lower its emissions that can be harmful to the environment. These include gases like carbon monoxide, hydrocarbons, and nitrogen oxides. To do its function effectively, the catalytic converter makes use of two types of catalysts known as the reduction catalyst and oxidation catalyst. The reduction catalyst is considered as the first stage of the catalytic converter, which is tasked to minimize nitrogen oxides emissions with the use of platinum and rhodium. The second stage is the oxidation that effectively reduces unburned carbon monoxide and hydrocarbons by burning them with platinum and palladium. The third stage of the catalytic converter is known as the control system, which oversees the flow of exhaust emissions to effectively manage the operation of the fuel injection system. Aside from the catalytic converter?s main function of making a car friendlier to the environment, it can also improve the fuel economy and engine performance of a vehicle.

Once the catalytic converter gets damaged, it loses its ability to fulfill its functions like preventing harmful exhaust emissions. To detect if one?s catalytic converter is on the verge of failing, one must carefully observe symptoms like a failed emissions test, frequent engine overheating, poor fuel economy, and deteriorating engine performance. If any of these signs is present, it is time to have the catalytic converter checked by a professional mechanic. If damage is confirmed, it is best to replace it as soon as possible to prevent further engine complications.

Better engine strength does not mean more fuel to burn because if that is the case, just imagine the potential air pollution from the millions of cars on the road?worldwide. With this recurring predicament at hand, car manufacturers, including Volvo and Audi, continue to innovate means that will help lessen the discharge of noxious gases of vehicles. The Volvo Catalytic Converter along Audi Catalytic Converter were designed to help reduce a vehicle’s emission further.

Lawmakers and automakers alike thought of means to solve this environmental problem. The former would create clean air laws, while the latter made some tweaking and refinements to their car engines and fuel systems. The Volvo Catalytic Converter treats the exhaust before it leaves the car and lessens the amount of pollution produced. Modern cars are now designed to help solve this environmental issue. The players in the automobile industry have manufactured a vehicle’s engine to carefully control the amount of fuel it burns. Not only does it save on the fuel, but also is friendlier to the environment.

Keeping the air and fuel ratio very close or keeping them at the stoichiometric point is a primary task of an Audi Catalytic Converter. All the fuel will be burned using all of the oxygen in the air. The fuel mixture also depends on the ideal ratio needed during actual driving of the vehicle. There are times when the mixture can be lean which is higher than 14.7 pounds of air and other times when the mixture can be rich which means a lower ration than 14.7 pounds of air. Of the three emissions from a vehicle (Nitrogen gas, Carbon dioxide, and water vapor ) Carbon dioxide is believed to contribute much to global warming.

Maintenance of catalytic converter, however, is often a major problem. An effective Audi Catalytic Converter’s function can be weakened by the activity or process itself due to two causes: poisoning of the active site by contaminants and exposure to excessively high temperatures. To maintain a catalytic converter’s crisp condition, it is advisable to use lead-free fuel and also to follow proper engine maintenance procedures.

For 80 years and counting, Volvo continues to be an advocate of innovation without sacrificing the environmental issues. Aside from the Volvo Catalytic Converter that Volvo Cars offer, the company has also adopted the environmental policy since 1945. Volvo has introduced life cycle assessment and calculation of the impact of each vehicle make using the EPS or Environmental Priority Strategies in car design. Like Volvo Cars, Audi is a car company that also has an outstanding regard to the environmental. Audi’s innovative technology does not take for granted the environmental protection, but at the same time do not forfeit performance, comfort, and safety of its patronizers. Catalytic converters may have different brands, but they all have the same cleaner act.

Nowadays, as the world gets busier, more vehicles are taking drifts on the road. This implies that with more cars, the more pollution we could get. Cities around the world especially here in the U.S. are doing numerous campaigns and other projects in order to save the environment from pollution caused by the toxic emissions of motor vehicles and other smoke-generating industries. Maybe we could not completely get rid of the pollution caused by vehicles but we could lessen the harmful effects that we and our environment suffer from. Moreover, laws on minimizing toxic emissions produced by vehicles are strictly imposed.

Most vehicle manufacturers of today have their own way of reducing these harmful effects. They now included additional components on the car’s engine and fuel system to do this. One of the devices developed by auto manufacturers that control the emission of pollutant in the internal combustion engine is the catalytic converter. A catalytic converter reduces the toxicity produced. It is located between the fuel system and the exhaust system of conventional vehicles.

Most modern cars that you can find out in the market today are already equipped with a catalytic converter that contains three-way system. The three-way system performs three different processes. The first process of the three-way catalytic converter is the reduction catalyst. In the reduction catalyst stage, it reduces the amount of nitrous oxide produced by the engine and converts it to much safer chemicals, like nitrogen and oxygen.

Next process is the oxidation catalyst that performs oxidation of carbon monoxide into carbon dioxide. The third and last process is the control system. Control system performs the last and the most significant task of a catalytic converter which is the oxidation of unburned hydrocarbons and then turns it into carbon dioxide and water.

The three processes performed by a catalytic converter occur before the actual emission of the exhaust. Catalytic converters contain several parts. The core, which is found in modern catalytic converters, is a ceramic or stainless steel honeycomb that supports the catalyst in performing oxidation. Another component is the washcoat. The washcoat is a mixture of silicon and aluminum, which is added to the core and forms a hard, rough surface. The washcoat was developed by car manufacturers to make the catalytic converter more efficient.

There are bunches of different catalytic converter brands you can find today like the Nissan Sentra catalytic converters, Ford catalytic converters, and other Nissan parts.

One of the most essential systems inside the car is the exhaust system. This is where catalytic converters are located. A catalytic converter, along with the exhaust manifold, exhaust pipes, muffler and resonator as well as the tailpipe and assortment of clamps and brackets all complete the line-up of primary exhaust components. Thus, problems rooted in the exhaust system of one?s vehicle whether it be an Avanti or Bertone automotive model, will most probably have a great deal to do with a few of these parts, one way or another. Though all pieces of the said system are expected to demonstrate decent performance and endurance, entailing a longer time between replacements, there are some components of the system that inevitably work a lot harder than others. The catalytic converter is one of them. Since the device is employed to lessen the degree of toxicity common to engine car emissions, it is exposed to harmful elements on a regular basis. If one drives the car everyday, then the daily exposure will more than certainly take its toll on the material of the converter and sooner rather than later, a new one will have to be installed and the old one discarded to ensure the car?s performance doesn?t suffer. An Avanti Catalytic Converter or Bertone Catalytic Converter won?t present too much trouble for those who feel that these are the catalytic converters to go for. Of course, in the way of such matters, one must also be certain to find out the specific models that the Avanti Catalytic Converter or Bertone Catalytic Converter will be installed to. The products, after all, must match the specs of the car in question. Choices for Avanti Catalytic Converters are available from a considerable number of sources online. The same case is true for Bertone Catalytic Converters.

Catalytic converters have come a long way since the power-sapping pellet catalysts of the 1970s. The modern honeycomb styled catalytic converters allow comparatively free flow of exhaust through your car’s exhaust system, while at the same time cleaning up harmful pollutants emitted from your engine. Catalytic converters do not last forever, but you are not going to pass an emissions test without a working catalytic converter. Therefore, you do not have a choice but to install or replace one.

Why do we need catalytic converters?

Fuel burnt in an engine produces harmful gases such as hydrocarbons; oxides of nitrogen and carbon monoxide, which is not at all safe for the environment. At such times the catalytic converters plays the most significant role by controlling the possible damages to the environment. The catalytic converter is installed between the exhaust line and the muffler where the chemical coating of the converter works as a catalyst and changes the poisonous gases into harmless inert gases. Preserving its own chemical properties, the chemical catalyst increases the speed of the reactions between two chemicals.

OEM catalytic converters, which come with the vehicle from the manufacturer, sometimes stop functioning efficiently. All converters have to be replaced at some time or the other, but because original catalytic converters are expensive, people prefer to go for replacement converters manufactured by OEMs.

Where is the catalytic converter located?

The side of the converter towards the engine contains a stainless steel container, which receives unsafe toxin gases from the engine. The honeycomb mesh present inside the chamber is coated with catalysts like platinum, aluminum oxide and palladium. These catalysts convert hydrocarbons and carbon monoxide to carbon dioxide and water vapor. There is a third lining of platinum and rhodium, which condenses the nitrogen oxide.

Do not use leaded fuel with a converter

Whether it is an OEM or any other catalytic converter, it is suggested to use unleaded fuel with it since the lead oxide produced in the fuel renders ineffective the lining of the catalyst chemicals. The only reason for using lead in the fuel is for lubrication. These days the law has made it compulsory to have Catalytic converters. Manufacturers have researched and designed special engine parts in order to withstand chemicals and the corrosive temperatures in the parts of the engine.

Summary

The best part about installing catalytic converters in vehicles is that emission of pollutants is reduced by about 96 percent from pre-control vehicles.

A vehicle’s exhaust system contribute to its overall performance, located here are the various components responsible for taking the exhaust away from the engine. The vital role these parts play, are what makes any vehicle run smoothly. But just because they efficiently emit those exhaust gases doesn’t mean it is all good. The emission should also be less harmful for the environment. To achieve this, the vehicle needs an effective catalytic converter. For car companies like GMC and Jeep, their catalytic converters are already built in the system.

GMC catalytic converter and Jeep catalytic converter help in reducing the toxicity of the vehicles’ exhaust. They basically remove harmful elements in the exhaust before they are released into the atmosphere. They do this by first keeping the air to fuel ratio very close to the stoichiometric point, which is the ideal calculation.

Most GMC catalytic converters and Jeep catalytic converters are three-way catalytic converters. This refers to the three regulated emissions they help to reduce, which are carbon monoxide, Hydrocarbons or volatile organic compounds (VOCs) and Nitrogen oxides (NOx) molecules. GMC catalytic converter and Jeep catalytic converter function in three stages. The first stage is The reduction catalyst, where platinum and rhodium are used to help reduce the nitrogen oxides emissions. In the second stage or oxidization catalyst, the catalytic converter reduces the unburned hydrocarbons and carbon monoxide by burning or oxidizing them over a platinum and palladium catalyst. The final stage is a control system that monitors the exhaust stream. It also here where the information is used to control the fuel injection system.

The GMC Catalytic Converter and Jeep Catalytic Converter are great solutions to minimizing air pollution. Today, some car companies are also offering hybrid cars, which are powered by both an internal combustion engine and an electric motor. GMC catalytic converters and Jeep catalytic converters are just alternatives, because they are either built in or installed later on.
