Course: Diesel Equipment Technology I (20107-I) > Section: Diesel Engines: Servicing the Air Induction and Exhaust Systems

Performance should include

- checking the boost, according to manufacturer guidelines
- using a PSI gauge and a manifold pressure gauge
- determining the needed action.

Process/Skill Questions:

- What safety precautions must be followed when checking an engine’s boost in a lab environment?
- Why are manifold pressure gauges measured in inches of mercury (inHg) vacuum?
