The document discusses the importance of using catalytic converters in cars to reduce pollution in cities like Saltillo and Torre坦n, Mexico. It notes that catalytic converters accelerate the transformation of exhaust gases into less harmful emissions. The document also explains that catalytic converters have a lifespan of around 80,000 km and need to be replaced if the car has traveled farther. It provides information on how to identify when a catalytic converter may no longer be working properly based on changes in engine performance.
2. Do you know ..That Saltillo and Torre坦n are the most polluted cities in Coahuila, this is because these two cities have more companies and citizens
3. What can we do to help?Well my idea is to raise awareness about the importance of cars verification and the catalyst.We need to take care of ours cars, change the oil, change the spark plugs, change the air and oil filters
4. Why do we have a verification for the cars?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
5. Lambda ValueThe lambda value is calculated with:Air-fuel value14.7The ideal air-fuel ratio is 14,7 grLambda > 1 === We have enoug air in fuel-air mixture.Lambda = 1 === We have a perfect combustionLambda < 1 === We have not enoug air in fuel-air mixture.
6. The importance of catalystDo you know what is a catalyst? This unit catalyzes the gases generated by combustion carsIt is very important because it accelerates the transformation of gases, but much people dont know this.
9. Advantages of using the catalystWe 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.
10. Now, how can I know when my catalyst is not working?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
11. Cost 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.UsedNew
12. What happen with the old catalyst?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? Just four business have more than ten, the other 20 business have less than 5 or no one.RomoDel norte
14. And they usually sell the catalysts because it have silver and platinum that can be reused. 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.
