Draco-REX Posted November 29, 2014 Report Share Posted November 29, 2014 Ducati's V8. Not just a theory, here's a 4 cylinder version in action: An article about it: http://thekneeslider.com/ducati-elenore-v8-update/ Quote Link to comment Share on other sites More sharing options...
STEVE-O Posted November 29, 2014 Report Share Posted November 29, 2014 More things to break, it's cool but why, ssc still uses a pushrod v8 fwiw Quote Link to comment Share on other sites More sharing options...
jeffro Posted November 29, 2014 Report Share Posted November 29, 2014 What the... I actually see less things to break. 6 less piston rods... those 2 would have to be strong as fuck though. Quote Link to comment Share on other sites More sharing options...

The pins that hold the 2 Pistons together, in sure a rod is much stronger, more mass yes by far but il take mass and strength anyday Quote Link to comment Share on other sites More sharing options...

aussiek2000 Posted November 29, 2014 Report Share Posted November 29, 2014 Looks like the outside pistons would come completely out of the bore when the center are at BDC. Quote Link to comment Share on other sites More sharing options...
Fubar231 Posted November 29, 2014 Report Share Posted November 29, 2014 I dont know about this.... If you wanted to make any power you would have to have some serious rod's on that thing, plus whatever connects the pistons together... Seems like there complicating the V8, but then again it could save weight... Who knows... Also this reminds me of a flat-plane V8 crank by the way the pistons and firing order is.

aussiek2000 Posted November 29, 2014 Report Share Posted November 29, 2014 It effectively only a 2 cylinder. Just instead of 2 large cylinders like a V-twin they split it across 8 pistons Quote Link to comment Share on other sites More sharing options...
Furloaf Posted November 30, 2014 Report Share Posted November 30, 2014 It's replacing rotational mass with more start-stop mass. I'm not sure if there's any difference but seems like the former would conserve momentum better. This design might require a more massive flywheel to smooth out the engine.

Guest GMoney Posted December 1, 2014 Report Share Posted December 1, 2014 Pretty cool idea. Pretty neat how the outter pistons actually "pull" the connecting rods and inner Pistons "push" on the conn rods. Quote Link to comment Share on other sites More sharing options...
