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.

Gasoline-powered vehicles such as your Pontiac are among the major contributors to urban air pollution. This can be attributed to the high quantities of nitrogen oxides, carbon monoxide and hydrocarbons that are being produced by the normal combustion process of your car. If these burnt gases are left uncontrolled, they would eventually contribute to urban smog, as well as heart and respiratory heart problems. To protect the air quality and improve the quality of air, your Pontiac vehicle has been equipped with a group of emission-control components known as the exhaust system. This group of car parts serves the main function of conveying burnt gases from your internal combustion engine. The Pontiac catalytic converter is an indispensable part of your exhaust system. It looks very much like the muffler, and can be usually seen mounted under the vehicle. It was first used in cars three decades ago, and has evolved into a more complex and more reliable emission control component because of automotive technology.
The number of catalytic converters installed on your vehicle depends on your car?s configurations. Some have 1 while others have 2 catalytic converters. But no matter how many catalytic converters you may have on your car, they still serve the same purpose?that is, to significantly minimize the harmful poisonous gases in your exhaust gases. A typical Pontiac catalytic converter is made up of a honeycomb form catalyst that is protected by a stainless steel canister. The interior surface of your Pontiac catalytic converter within the honeycomb structure is coated with catalytic metals such as rhodium, palladium, and platinum. There are 2 catalysts present in every catalytic converter?an oxidation catalyst and a reduction catalyst. The oxidation catalyst burns all the byproducts of your fuel combustion such as the carbon monoxide and hydrocarbons. On the other hand, the reduction catalyst ensures that the nitrogen oxides are turned into harmless emissions.
There are 2 types of catalytic converter: the two-way converter and the three-way converter. Also known as an oxidation catalytic converter, the two-way catalytic converter makes use of the oxidation process to transform the harmful pollutants into harmless gases. Through adsorption, the oxygen molecules, carbon monoxide, and hydrocarbon are simplified into water vapor and carbon dioxide, which eventually goes out of the tailpipe. The three-way catalytic converter oxidizes the hydrocarbons and carbon monoxides and at the same time transforms the nitrogen oxides into less harmful nitrogen and oxygen. This type of catalytic converter is used in conjunction with the feedback engine management and fuel injection of the car. Your Pontiac catalytic converter can last for over 100,000 miles if properly maintained. A worn out catalytic converter can decrease the performance level and fuel economy of your engine, aside from contributing to urban pollution and health problems. You can easily determine if your Pontiac catalytic converter needs replacement when you hear some rattling noises from the catalyst, especially when your car is increasing speed. A defective oxygen sensor and poor maintenance are some of the leading causes of a worn out catalytic converter. So when this happens, do not think twice on replacing your defective Pontiac catalytic converter with a new one in order to maintain the emission control functions of your car.
