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.
