Anything of here in character 😝 <| sep |> So what I ' m reading here is that you want to use small electric motors to turn cams that open the valves ? You ' re gonna need some pretty damn torquey motors to pull that off . But even if you managed to find adequate motors , you ' re gonna find it just about impossible to actually control the speed . They ' d not only need to be running at 12 the crank speed but also perfectly in phase or you run into issues like advancedretarded valve timing , power loss , and destructive piston to valve contact . Speed will be extremely difficult to control as every revolution will see a coasting stage with minimal power requirements , a ramping up stage as it is working very hard to push the valve open , and a driven stage as the motor suddenly goes from pushing against the valve spring to being helped by it . I don ' t think you have the slightest shot of making this work .
