Hello All:

DragonCommando:

What a satisfying feeling to read your post on "Compression Braking" (NOT) and finally have a solid grasp of what's actually happening! This has been a vexing issue for me (and I'm sure many others) for quite a while and in an effort to Google my way to an answer, I had to travel through the minds of many uninformed posters who demonstrated a vast ignorance of the subject (fortunately, during my journey, I was not wearing my good shoes...ahh, the Pythons). BTW, I suspect from your frequent use of single "L's" in spelling (ie:actualy) that you are not from the colonies.

Many of the other articles I found drifted off into Jake Brake land, which was of little use, and some got too heavily into thermodynamics.

Thanks again for the 411! I have saved your post in my favorites and have already shared it with several friends and associates. It's not .org, or .gov (my preferred sources), but accomplished it's purpose. Have you considered a visit to Wikipedia...the definition there is in desperate need of your services!

Cheers,

Steve Waclo EE, Ret.
