Understanding Emissions

This course brings the mystery of exhaust gases to light by looking at gasses produced by combustion. You will see that by looking at the tail pipe emissions, you can diagnose a range of faults from misfire, to faulty catalytic convertors.

By the end of this course diagnosing and discussing CO2, CO, HC will seem like second nature. This covers all petrol engines

Content
