Understanding Engine Timing, AFR, and tuning

I had the unique opportunity to design my own experiment for my last couple of weeks of an engineering lab as I'm graduating.

Knowing how much there is to try and learn and understand about internal combustion engines and how to tune them properly and understand timing and so forth, my group and I worked hard to develop an experiment and record data and develop a lab report that would be beneficial to a lot of people.

So here it is! First I'm posting a link to the actual lab report document. And then I'm going to post the lab report piece by piece in this thread.

Link:

http://www.cae.wisc.edu/~nackers/car...t%20Report.doc

I recommend everyone to read it, you'll probably learn at least something, or it'll reinforce your knowledge. I'm happy to answer questions about anything as well. So enjoy the long read, and I hope it helps you in your quest to understand engines and engine tuning!


Later!

Steve

cool, so you put a Mondeo on the dyno or what car was it? And on the equipment list ... 2 intake manifolds per cylinder? What does that mean? The duratec was a DOHC having four valves per cylinder two intake two exhaust. So the area where the valve sits ... is that called a manifold? I know the manifold to be something else.

He probably meant intake valves per cylinder. Steve, you're quickly earning the title of Sticky King. Thanks for another fun tech read.
