I've had this idea for years now... with all the technology that has gone into modern engines why can't they design a NEW engine that has computer controlled solenoids to open the valves. This could eliminate the camshaft, timing gears and timing chains which are frequent cause of needed engine wear repairs/ failures.
Also eliminate throttle bodies as they are no longer needed, no need to have EGR valves as you can infinatly adjust the intake closing point to reduce cylinder pressure, they could eliminate oil to the entire top of the engine (valves could get permanent lube like a wheel bearing and you would have no rockers, lifters, timing gears/chains to oil) and could have such a broad range of power that we would be able to go back to less complex transmissions, no 10 speed needed if it makes lots of TQ down low and HP up high...
