Transcript of Catalytic Converter, The Automatic Exhaust System
The exhaust contains toxins that can
be injurious hence a catalytic
converter is invented to eliminate
this danger.
Petroleum is made up of
hydrocarbons which is
formed when the tiny
sea creatures rot down,
heat up and get squeeze
by layers of sea bed
rocks.
If you burn any kind of
hydrocarbon with oxygen
from the air, it will release
energy along with CO2 &
water along with other
poisonous gases.
And the gases emitted by a
car engine include various
poisonous gases like carbon
monoxide & nitrogen oxides
that cause smog.
Within the catalytic
converter a chemical reaction
takes place in which noxious
fumes are turned into less
harmful matter.
One of them is connected
to the engine which brings hot
polluted fumes from the
engine’s cylinders & Second
pipe is connected to the exhaust.
When the gases blow over the
catalyst, chemical reaction takes
place, converting the polluted gas
to some other gases that are safe
enough.
HC
• This is in the form of unburned gasoline
CO • Created by the combustion of
gasoline
NO2 • Produced when the heat of the
engine forces N2 to combine with O2
Converted from the hydrocarbons
CO2 &
H2O Converted from the carbon monoxide
CO2
Converted from the nitrogen oxide
N2 &
O2
Precious metals like platinum,
palladium and rhodium are
used in catalytic converters to
remove toxins from the engine.
The price of these valuable
metals are around hundreds of
dollars .
If you find someone acting suspiciously
around your vehicle, report it to the
nearest police station.
