MEC2040 Fuel & Exhaust Systems
Intermediate · 1 credit · TMT - Trades, Manufacturing and Transportation
- Description
- Students diagnose, maintain and service the fuel and exhaust system of a typical four-cycle gasoline engine.
- Prerequisite
- MEC1040: Engine Fundamentals
- Parameters
- Access to a ventilated area, a fuel pump vacuum/pressure tester and related resources, and to instruction from a certified technician when working on a customer vehicle.
Outcomes The student will:
1 demonstrate safe work practices when working with volatile liquids and combustible gases
