Catalytic Converter Testing Part 1 - Smog Tech and Repair Certification: ASE TEST TIPS:

Free ASE Prep: Catalytic Converter Testing - This video is describing one of the ways to test a Catalytic Converter, on of the subjects I describe on my http://asetesttips.com/ase-certificat... blog. Sorry this video is only 4:30 long not 11:40 In the combustion process gasoline, combines with Oxygen from the air to create water (H20) and Carbon Dioxide (CO2). Remember gasoline needs oxygen to burn and inside the cat the extra air is needed for the oxidation process. Also in the combustion process Carbon Monoxide (CO) combining with Oxygen (O2) creates carbon Dioxide (CO2). This reaction also takes place in the converter when the air/fuel mixture is lean. Now, to reduce Nox or Nitrous Oxides we need Carbon Monoxide to remove the oxygen from the Nitrous Oxides (Nox) so we can get nitrogen (N2) and Oxygen (O2). (CO2) Carbon Dioxide is also a byproduct of this reaction. Note: Replacing a CAT on a vehicle that's running to lean will not reduce Nox, Free ASE Prep: Catalytic Converter Testing see part 2
