Engine Management

Additional information...

I can provide a bit of background on engine management strategy, and what goes into making of engine controller code. The timing operations, and what needs to happen when. How to work with single coil or coil on plug. Using normally aspirated, throttle body or direct injection of fuel.

Dear me, The gauntlet has been dropped. I was telling a friend about my idea and what I was using, and got the response I was hoping to hear. He was telling a third party that does work for a "major auto manufacturer" and was told the idea it was preposterous, and it would never work.

So now I have a problem, what do I do with code that can take input from potentiometers acting as MAP, ECT, and IAT, and simulated cam (single pulse, half moon, VVT, and Mopar 4,6, and 8) and crank signals (4x to 60-2), and provides timing for up to 8 cylinders (single, dual, or coil on plug) from 150 up to 10000RPM using an Arduino Nano.  Unless, he thought I needed more hardware, like IGBTs or a CD charge pump or something, because I do need that part.  But from what I got from my friend, the third party didn't think the Nano was up to the task. We shall see.

Jack keep updating us on your interesting work!

Hi Gary,

Thank you for the encouragement. I will be publishing a short series in the documents section that covers elements of engine management. The current engine controllers use a "just in time" kind of methodology, which sometimes has to play catch up, and can get a little confused. My method operates off a different process, what messed up a friend was when I said my process can use a 4x wheel to run a 6 cylinder motor, as long as I can detect TDC0, everything else is just more detail.

Jack.

Hi Gary,

I posted the start of my first article, for lack of a better location, in the Arduino section.  I used a Mega 2560 for my initial platform.

Hello Jack,

I can't find that article - can you give us a link.

It's  a long time since I worked on automotive and even then it was never directly on engine management although controllers I built had to talk to engine management systems and I haven't totally lost touch.  There is no way an Arduino nano can replicate current, legislation compliant, engine management systems - since not only do you need to control the engine and emissions (or fake it like VW) but you need to detect and log misfires and faults. The tiny processor in the nano doesn't have enough ROM for a basic map and certainly doesn't have the processing power to calculate it on the fly.

You might be able to replicate a traditional distributor and centrifugal advance system with a nano - but why bother ?

Hi Michael,

The article is still in draft status, which requires me to add you to the list of collaborators. I should have that today. If I run into any problems, I will be contacting you.

Updates. forgot to post here, I have completed 4 installments for the Engine Management in the Arduino section.

Hello Jack,

I can't find them (looked in your activity section and in the Arduino section) - why not post them in your personal blog space on E14 ?

Posted a Blog, let me know if you can find it. Also if you can answer my question, that would be very helpful.
