Description

 


This course, “F.R.E.D, Directs the Injection,” is a continuation of the popular Dave Hobbs series on “Frustrating, Ridiculous, Electronic Devices” in covering the mysteries behind Gasoline Direct Injection (GDI) systems. Dave’s presentation will present not only on GDI systems but also Sequential Port Injection (SPI) and how the two delivery methods work together. The course will cover hands-on diagnostic techniques utilizing scan tools, scopes, and meters, tips and tricks on examining the high-pressure mechanical GDI pump, as well as an exploration of 3-phase brushless fuel tank delivery pumps. Diagnostics are followed by advice on recommendations for proper R&R of fuel injectors and fuel pumps.

Course Objectives:

At the end of this session, the student will be able to:

  1. Understand the definition of Gasoline Direct Injection (GDI) systems and why they are important
  2. Show knowledge on GDI fuel rails and pumps
  3. Define high-pressure GDI fuel line and low-pressure GDI fuel lines and their relationship with voltage sensors
  4. Describe the differences between GDI and Port Fuel Injection (PFI)
  5. List the types of GDI spray strategies
  6. Summarize the strategies of GDI 3-phase fuel pump systems
  7. Underline the flow of fuel from the tank to a combustion chamber in a GDI system
  8. Categorize proper safety techniques when interacting with GDI systems
  9. Illustrate the dangers involved with GDI voltage and system pressures
  10. Recall the appropriate personal protective equipment to be used in servicing GDI systems
  11. State the procedure for depressurizing the GDI high-pressure system
  12. Demonstrate overall knowledge of diagnosing and repairing of low-pressure GDI systems
  13. Understand the proper tools, gauges, and meters required for GDI diagnostics and repair
  14. Recall scan tool PIDS that directly relate to the GDI system
  15. Demonstrate the capability of interpreting GDI scan tool data
  16. Show knowledge on current ramping diagnostics for fuel pumps
  17. Demonstrate an overall understanding of diagnosing and repairing high-pressure GDI systems
  18. Name common GDI system service issues
  19. Communicate available solutions for intake carbon cleaning
  20. Explain preventive methods for reducing carbon deposits
  21. Illustrate the operation of GDI injectors
  22. Describe how SFI and GDI systems work together
  23. Describe the procedures for servicing GDI injectors
  24. Recall the differences between homogenous and stratified fuel mixtures

    Great info. A few key items would be video and audio detail which surprisingly most YouTube guys like Scanner Danner have in spades over AVI. Cheaper quality with your videos are not good. Detailed locational shots of what you are doing and where you are doing it especially in scope info. Scope info is poor with no settings provided. Most of us viewing these videos are well versed in settings but some new guys getting in to scopes or this system would enjoy and prefer the brief explanation. Service info should be researched more in depth. When you give the example of “10% off the top of your head” type of an opinion, you should definitely shout out to the engineers of at least the aftermarket makers of these pumps and systems since they will know a little more. Stop trying to lightly spam videos for Delphi. Delphi makes good products and doesn’t need to be injected in to the videos at all unless of course they are sponsoring the entire thing. This video is good again, but this could have been a $50 webinar not a $100 course.

      Hi Erik – Thank you for leaving your evaluation of this course.
      For more detailed training on scope settings, we recommended to view: LBT-393 Labscopes for the New user and LBT-326 Basics of Labscopes
      Overall, this is great feedback to help us continue to improve our training offerings.
