How much fuel do various types of engines burn per power output? I'm especially interested in naturally aspirated piston engines, and comparing two-stroke to four-stroke.

The wikipedia article gives the value for several specific engines, but they're mostly for either aircraft or marine applications.

I don't know if engine manufacturers openly publish those specifications. I am sure they have them in a document somewhere but I doubt they are easy to find. Good luck finding them though. –  Mike Saull Apr 30 '13 at 18:36
    
Mayhaps, if none of better, better fit would be on Physics.SE? –  theUg May 1 '13 at 19:20
