Catalytic Converters Digimaster 3

Speaking before the catalytic converter, let  Digimaster 3 a simple understanding of the components of the engine exhaust. Gasoline is a hydrocarbon, and in the gasoline molecules almost all carbon and hydrogen atoms, these carbon and hydrogen combustion is supposed to produce carbon dioxide (CO2) and water (H2 (Gallery Forum) O), but because of the small amount of mixture incomplete combustion, and there will be a little oil (not burning there to burn) is emitted, it will produce HC (hydrocarbons) and CO (carbon monoxide). Furthermore, into the air within the engine, containing eighty percent of nitrogen (N2), but after the high temperature of the combustion chamber, and was very stable nitrogen, and oxygen (O2) in the air in the compound, to produce NO and NO2, collectively referred to as NOx. HC, CO and NOx can cause environmental pollution and harmful to the human body, so the world will develop environmental regulations for vehicle emissions restrictions.
Environmental regulations are quite stringent vehicle emissions standards, regardless of idle, acceleration, low speed, high speed or deceleration, must comply with the emissions standards, the vehicle in the face of such harsh restrictions, in addition to strike a balance between performance and sewage In addition, only the "Tip" is catalytic converter. The catalytic converter is usually precious metals as raw materials, oxidized catalyst, reduction catalyst and the vast majority of vehicles using the three-way catalytic converter.
They connected to the catalytic converter from the exhaust manifold after incomplete combustion pollutants converted into harmless substances, protection of the environment.
Come back on a simple chemistry class, HC and CO in the sewage are incomplete because the combustion of the  
Digimaster 3 For Sale produced to eliminate they must burn them, that is their oxidation, so this is the task of the oxidized catalyst. And the generation of NOx is because nitrogen is due to oxidation, it must be reduction catalyst for NOx reduction to nitrogen. The three-way catalytic converter is the oxidation of HC and CO and NOx reduction occurred in the same catalyst. "Catalyst" does not participate in the chemical reaction of oxidation or reduction, it is only the catalyst in the chemical reactions.
