The importance of catalyst

  1. 1. The use of catalysts<br />By: Alexis Rodríguez<br />
  2. 2. Do you know …..<br />That Saltillo and Torreón are the most polluted cities in Coahuila, this is because these two cities have more companies and citizens <br />
  3. 3. What can we do to help?<br />Well my idea is to raise awareness about the importance of car’s verification and the catalyst.<br />We need to take care of ours cars, change the oil, change the spark plugs, change the air and oil filters<br />
  4. 4. Why do we have a verification for the cars?<br />It was created to have a better control of the pollution generated by the cars. It was established in Saltillo in the year 1992, but it is a nationwide program, even though some states do not enforce this application<br />
  5. 5. Lambda Value<br />The lambda value is calculated with:<br />Air-fuel value<br />14.7<br /><ul><li>The ideal air-fuel ratio is 14,7 gr</li></ul>Lambda > 1 === We have enoug air in fuel-air mixture.<br />Lambda = 1 === We have a perfect combustion<br />Lambda < 1 === We have not enoug air in fuel-air mixture.<br />
  6. 6. The importance of catalyst<br />Do you know what is a catalyst?<br /> This unit catalyzes the gases generated by combustion cars<br />It is very important because it accelerates the transformation of gases, but much people don’t know this.<br />
  7. 7.
  8. 8. Parameters of gases<br />Without catalyst.<br />3 way Catalyst<br />open cycle.<br />3 way Catalyst<br />closed cycle.<br />
  9. 9. Advantages of using the catalyst<br />We can reduce the polluting gases but we should know that a new catalyst has a life span of around 80,000 km, so if your car has more than 80,000 km, you must change your catalyst.<br />
  10. 10. Now, how can I know when my catalyst is not working?<br />It is very easy if you have had the car since it was new, you will notice a little change in the machine, the power could be less strong, and the rpm might also be less responsive<br />
  11. 11. Cost <br />A new catalyst is around $ 1200 and a used one is around $ 250. The true is: we need this machine because a perfect combustion is very very difficult and without a perfect combustion, the car produces pollution gases.<br />Used<br />New<br />
  12. 12. What happen with the old catalyst?<br />Well we visited around 24 Auto parts business and we asked there: What they usually do with the catalyst? And how many catalysts did they have?<br /> Just four business have more than ten, the other 20 business have less than 5 or no one.<br />“Romo”<br />“Del norte”<br />
  13. 13. “Rodríguez”<br />“El muñeco”<br />
  14. 14. And they usually sell the catalysts because it have silver and platinum that can be reused.<br /> So if your catalyst is clogged or is old, you can sell it, earn $ 250, and buy another one, if you do it, you will help to protect the environment. <br />
