273,
If your BS was correct, everybody would be building engines with 7" pistons & 2"stroke. Oh, the free hp because of the large piston area!!!!
The rubbish you posted in post #78, you posted a few weeks back. I thought I will let it go. But then you repeated it....
One more try for the dumb: you hit a two inch nail into a piece of wood with one hammer blow. The hammer blow [ force ] represents the force from the burning mixture. Now get a piece of steel rod, about 5/16 " thick [ old p'rod ] & grind a point on one end [ like a nail ]. Using the same force on the hammer, hit it. It does NOT go into the wood as deep as the thinner nail even though the same force was used because the force was spread over a greater area.
