Clean up the mess

jack.chaney56

Tried to create a lesson for making an engine controller, and things got way out of hand, so I will be attempting this again, but try to maintain a better structure.

  • Tools, the controller needs to be a controller first, so provide code for sensor inputs, and calibration.  Also communication to get state information while controller is active.
  • Basic ignition and timing
  • Modeling the ignition management, and units of measure (accuracy versus significance)
  • Walk through an ignition event for a single cylinder.
  • Special cases for starting.
  • Special cases for rev limiting
  • Special cases for alternative fueling
  • Limits for system

 

After the ignition is done, and all the issues with calibration adjustment and timing, the next phase is fueling.

  • Mass air flow
  • Steady state equation
  • Asynchronous fueling
  • O2 Feedback PID

    Hi, and thank you.  I have a lot of information rattling around in my head and just need to get it written down. I have some gaps in the information that I think needs to be included, especially in the area of calibration theory. I am an embedded computer person, not a real car guy.  Also, as I think I mentioned, my major focus is on software and not hardware, so my "engine controller" will have rather simplistic methods for coil management and actuating fuel injectors.

     

    I think I will be presenting as each subtitle as a blog post first, and perhaps a book later.  I will be providing source code as well to run on an Arduino Nano or Uno.

    That's great, looking forward to it.
    It will be more helpful if you make Video lectures on that as well like did. Those videos helped me understanding power supply.
    I know members here are very experienced and it would be helpful to others if they share their knowledge of their respective fields by lectures. Just like big universities are doing by collaborating and building courses for example udacity, coursera, edx etc.
    I'm also thinking of creating a seperate group related to Video lectures given by experienced members on element14?
