As we know air pollution is big challenge for the world The air pollution due to automobile is 70% of total pollution of air pollution. We have several way for controlling automobile pollution. The most effective way is by using catalytic converter in automobile In short catalytic converter are used to convert the harmful gas to harmless gas

5. INTRODUCTION
• As we know air pollution is big challenge for the world
• The air pollution due to automobile is 70% of total
pollution of air pollution.
• We have several way for controlling automobile pollution.
• The most effective way is by using catalytic converter in
automobile
• In short catalytic converter are used to convert the
harmful gas to harmless gas

6. What is catalytic converter?
• It convert harmful gas into harmless gas with the help of
catalyst
• It is pollution reducing unit
• It placed between the exhaust manifold and the silencer
in the vehicle

7. CONSTRUCTION
Basic component are:
• Substrate
• Catalyst
• Mat
• Can
• Shields

8. Working
• When the exhaust gas come out of the engine it goes to
the catalytic converter
• The gas such as NOX , HC and CO are present in
exhaust. All these gases are treated in catalytic
converter producing harmless gas like CO2,H2O and N2
which are safely released in the atmosphere with the
help of catalyst
• Catalyst is material which promotes chemical change
without chemical reaction

10. Type of catalytic converter :-
1)Two way :- 2)Three way :-

11. Two way catalytic converter :-

12. • Three way catalytic converter:

13. ADVANTAGES
• Reducing amount of CO, HC and NOx, particulate
emission.
• it leads to pollution free environment.
• Having long life.

14. Disadvantages
• Cost is high
• Volume required is high
• There is over temperature problem
• Catalytic material is lost

15. APPLICATIONS :-
• Catalytic converters are used with internal combustion
engines fueled by either petrol (gasoline) or diesel.
• including lean-burn engines as well as kerosene heaters
and stoves.
• they are also used on electrical generator , forklifts,
mining equipment, truck , busses,
locomotives and motorcycles.
• They are also used on some wood stoves to control
emissions.

16. CONCLUSION
• The catalytic converter was successfully
designed and fabricated.
• The increase in inlet cone length reduces the
backpressure and also reduces the recirculation
zones.
• Installation of the catalytic converter reduces the
brake thermal efficiency and increase the brake
specific fuel consumption, fuel flow rate.
• At lower temperature the catalytic converter will
be inactive. The heat release due to chemical
reaction does not play a significant role.
