Could a solenoid be constructed to mimic
the proper valve position vs time curve of a
engine cam shaft? Maybe a circuit and/or
several coils in each solenoid?
That's the only problem but it may be tricky or
impossible to build such a solenoid that works
well over all rpms. But if it could be built, it
could be mass produced very cheaply, maybe
cheaper than a cam shaft.
The other concerns such as force necessary to
accelerate valves (are solenoids orders of
magnitude more inefficient than cams?) and
mangled valves from electronic failure (like other
fail safe systems set the default of every valve
in a safe position) shouldn't be problems.
