A division of General Motors, Buick also exemplifies the commitment to environmental and social responsibility. It is also following the commitment of GM in ensuring lesser emission and less fuel consumption. With cars getting plenty everyday and each one is a potential source of air pollution. Emissions standards and laws are very important to protect our environment and our health. That is why each Buick is equipped with the required catalytic converter so that its emission can be regulated and controlled.
A Buick catalytic converter treats the exhaust before it leaves the car and cleans it to make sure no harmful and poisonous substance comes out. The three harmful pollutants that go with the main and not so harmful emissions are the carbon monoxide (CO), hydrocarbons or volatile organic compounds (VOCs) and the nitrogen oxides (NOx). These by-products of combustion are said to contribute to smog and acid rain. The catalytic converter contains two catalyst are the reduction catalyst and the oxidation catalyst. The first stage helps to reduce the NOx emissions by using the platinum and rhodium. The second stage is where the unburned hydrocarbons and carbon monoxide are burned (oxidizing) over the palladium and platinum catalyst. The oxygen sensor then tells the computer the amount of oxygen which can be adjusted thru the air and fuel ratio and to make sure there is enough oxygen in the exhaust to allow oxidation catalyst to burn unburned hydrocarbons and CO.
Your Buick catalytic converter can get clogged and you will then hear a whistling sound when you try to rev up. That would mean a replacement is necessary. Replacing your Buick catalytic converter need not be expensive and difficult. Just check our online store for a brand new Buick catalytic converter and you’ll be back on the road in a jiffy.
