Audio-Visual Resources:

  • Slides:  70
  • Video:  28 minutes

Approximate length: 8 hours

CAAT Seal or Certificate available upon following quality assurance standards

Technicians review emission theory by applying exhaust gas analysis techniques to achieve effective enhanced emissions repairs and solve driveability complaints. It addresses the fifth gas, NOx, covering theory production and control. Technicians learn about mixture modulation, and how it relates to the Emissions Triangle. Explore catalytic converter conditions, operation, laws governing service, and testing procedures.
