They are quite a bit "cocked" in the 360 link, so they definitely move in some fashion (I think it was less visible in the static pics).
Why would they move twice? Just interested to hear your logic. |
Sorry, just saw this. Because I believe the lobe on the camshaft will make 2 revolutions in the 4 stroke set up. There would be no way to negate the second opening of this valve but it is possible the valve was timed not to fire fuel on the second open and closing. In fuel injected cars, this is done electronically now. An electronic fuel injector will fire up to 80/second. Yeah, that is fast. At any rate, I do not see any other port on that head to inject the fuel. Being this was a mechanical injector and placed dead center of the cylinder, it could only be the fuel injector.
