Very interesting concept of heads

Basically getting rid of the cams and valves and incorporate it all in one system. I bet that is exspensive to do as you have to have a completely custom head made. I just found it interesting.

 

I love technology...that's pretty damn cool

Don't show that to vette owners, though

 

It's old technology but just cool. There are some flaws with longevity on those but again still cool.

 

Yessir I Like it!

 

What longevity issues did they run into?

 

No coolant goes to the heads so heat and such.

 

Yeah I was wondering about that...that and the lack of lubrication to the "valves." I mean with them having to seal, they have metal to metal contact which seems like it would slowly damage bearings without any sort of lubrication.

 

As far as the lack of lubrication....the answer to that is ceramic bearings.

 

Edit: looks like from what I can tell about the pictures, they just spin around and around. Not sure how they would seal well...but I guess they do. Even such bearings would seem to work better with some form of lubrication or cooling such as those in bb turbos.
