Located in the exhaust pipe after the exhaust manifold and before
the muffler, its purpose is to convert unburned hydrocarbons in the
exhaust gases into harmless elements before they enter the
environment.The catalytic converters shell is made of steel much
like a muffler, but inside it’s much different.Catalyst materials
that coat a ceramic honeycomb-like structure react with harmful
gases such as nitrogen oxide and carbon monoxide.After reacting
with catalyst materials that coat the honeycomb, the exhaust gases
pass harmlessly into the environment.When an engine isn’t running
properly and high levels of pollutants or unburned fuel are in the
exhaust gas, the catalytic converter can’t keep up.High heat levels
result that damage the honeycomb, or the catalysts can become
poisoned by substances that render them ineffective. When that
happens, the catalytic converter must be replaced.
Application of catalytic converter:
Although catalytic converters are most commonly applied to exhaust
systems in automobiles, they are also used on electrical
generators, forklifts, mining equipment, trucks, buses,
locomotives, and motorcycles. They are also used on some wood
stoves to control emissions. This is usually in response to
government regulation, either through direct environmental
regulation or through health and safety regulations.
Catalytic converters require a temperature of 800 degrees
Fahrenheit (426 °C) to efficiently convert harmful exhaust gases
into inert gases, such as carbon dioxide and water vapor.
Therefore, they are placed as close to the engine as possible.
A 2-way (or "oxidation", sometimes called an "oxi-cat") catalytic
converter has two simultaneous tasks:
Oxidation of carbon monoxide to carbon dioxide: 2 CO + O2 → 2 CO2
Oxidation of hydrocarbons (unburnt and partially burned fuel) to
carbon dioxide and water: CxH2x+2 + [(3x+1)/2] O2 → x CO2 + (x+1)
H2O (a combustion reaction)
This type of catalytic converter is widely used on diesel engines
to reduce hydrocarbon and carbon monoxide emissions. Because of
their inability to control oxides of nitrogen, they were superseded
by three-way converters.
Three-way catalytic converters (TWC) have the additional advantage
of controlling the emission of nitric oxide (NO) and nitrogen
dioxide (NO2) (both together abbreviated with NOx and not to be
confused with nitrous oxide (N2O)), which are precursors to acid
rain and smog.
Since 1981, "three-way" (oxidation-reduction) catalytic converters
have been used in vehicle emission control systems in the United
States and Canada; many other countries have also adopted stringent
vehicle emission regulations that in effect require three-way
converters on gasoline-powered vehicles. The reduction and
oxidation catalysts are typically contained in a common housing;
however, in some instances, they may be housed separately. A
three-way catalytic converter has three simultaneous tasks.
