Given that no form of rotary/turbine is going to displace the reciprocating engine any time soon and given the wide acceptance and gradual improvement in electronic injectors I put it to a couple of old petrol heads the other day that doing away with camshafts and conventional valve gear would be a wonderful opportunity for the boffins to make life really interesting.
Imagine an engine with a electronic computer controlled gizmo operating each valve and imagine the wonderful overlaps and dwell times that could be dialled in. One of them reckoned it was doubtful a small enough gizmo could be built that would generate the necessary force to open a valve and then some one suggested sleeve valves and about then my eyes glazed over and I had another rum.
Any one out there with opinions?
Cheers.
