Exhaust and Emission System

Exhaust and emission systems on newer vehicles have become more complex than in the past. The emission system is used to monitor air-fuel ratios and has many benefits to the operator and the environment. For many years, automotive manufacturers were just concerned about getting the hot and toxic exhaust gases out to the side or rear of the vehicle. Today exhaust and emission systems are complex mechanisms that provide safety, efficiency, and concern for the environment. Periodically, exhaust and emission system components need replacing. This course will help you define the purpose of the exhaust and emission system, identify and explain the components in an exhaust and emission system, and inspect exhaust and emission system components.
