Re: No Camshaft
It seems like I remember some engine builder experimenting with hydraulic operated valves at some point long in the past. The control system & timing would be a nightmare but a person could theoretically control the valve lift & duration too. It would eliminate the need for a cam but bring other problems along for the ride, like leaky servos for one.
I guess we will have to settle for the mechanical cam & just choose the most appropriate grind for the task at hand. Would be neat to have an instant hot rod when you wanted one though.
