Catalytic converter .

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 C an S hields

8. Working When the exhaust gas come out of the engine it goes to the catalytic converter The gas such as NO X , 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

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

10. Two way catalytic converter :-

11. Three way catalytic converter:

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

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

14. 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 .

15. 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.
