Are related rates of change not calculus? As far as I have learned them they are (1st year Uni)...

lol @ above post.
@ Snaps assuming a relatively simple model for conflagration, it's probably not very hard to model the combustion chamber and figure out how to get good, complete burns. Obviously there are other problems to deal with however when thinking of designing the engine such as frictional loss, which is probably greater if you have a longer stroke and narrower bore, and of course stress on the components due to higher piston speed. I imagine gasoline burns so quickly that under many circumstances this doesn't really make a big difference.

Though so
Just thinking to myself though
It wouldn't surprise me if they did do something like what I said, but I wouldn't hesitate to admit that it's likely
far more compicated than I imagine.
