Assuming that it does...no valve train, higher specific output (one revolution per power stroke instead of two) hence less weight to drag around. And with the two-engines-inline idea you don't have any parasitic losses (except for mass) from the extra cylinders when you don't need them. Takes Cadillac's Northstar idea to its logical conclusion. >Beware of anyone trying to sell you a Carnot Engine solution. Not to worry, I bet nobody on my street has even heard of one. I understand they're very common in Erehwon, though -- I'll pick one up next time I'm there. ;-) Yours, David |
