Engine Control Systems

Engine Control Systems I

  • Recommend Electric I, II and III before taking this class
  • Theory of operation of compression, ignition and fuel systems
  • Early fuel delivery, carburetor diagnosis and repair (Electric feed back carburetors used in class)
  • Ignition systems and controls (Starts with points type and finishes with electronic type)
  • Ignition scope analysis
  • 5 gas overview and understanding of how each is formed and what it means
  • Early emission controls and variations including retrofit types.

At the end of the class students will understand compression, ignition and fuel delivery systems. This class establishes the foundation for computer controlled systems and sets the stage for all the following classes. Students will have overhauled a late model carburetor, bench tested distributors and used scopes to analyze engine operation.
