Course Description: This course introduces the theory, operation, and repair of the ignition, fuel, engine management, and emission control systems on gasoline and diesel-powered vehicles. It will help students identify, analyze and devise comprehensive assessments and diagnostic procedures of vehicle issues or abnormal operations commonly seen in the industry.

Objectives

Upon successful completion of this course, the student should be able to:

  1. Describe the theory and operation of various types of automotive ignition systems.
  2. Describe the theory and operation of various types of gasoline and diesel fuel systems.
  3. Describe the theory and operation of the gasoline and diesel computer-controlled engine management system.
  4. Describe the theory and operation of various gasoline and diesel engine emission control systems.
  5. Describe the theory and operation of gasoline and diesel induction and exhaust systems.
  6. Properly use scan tools to monitor, interpret, record, play-back and up-load ve data stream information.
  7. Create an industry-based diagnostic procedure that appropriately considers all systems and sub-systems of the modern automobile.
