Ferrari Mailing List: Re: Ferrari Filed a Patent for an Engine With Pill-Shaped Pistons

[Rick Moseley (ramosel]

Honda did this years ago...  only they oriented the piston length with the crankshaft and used two con-rods per piston.  Made for a very tight V motor with long length.  But a V4 almost the size of a V8 but with all the power and fewer moving parts.  The Ferrari version (of course) is the reverse.  Pistons are 90° rotated to the crank centerline. It will make for a very wide motor but it will be very short.   Honda did it to use 8 valves per cylinder.   Try that geometry with the Ferrari layout....  yeah, it's not going to go well.

It will probably be futile anyway.   If Honda could have made it work, they would have.   They could never get the rings to seal correctly on the flat sides of the oval.

This seems like a Ferrari concept developed over a multi-Cinzano lunch.
