TOO MUCH VALVE SPRING

I explored designing/creating an active spring system for engine value trains. The idea was to use a spring material that more easily collapses to open valve. But then becomes ridged under electric field to close value at timing. 20 years ago the materials were available, but not strong enough to stand up to engine valve stress. The idea of course was to greatly reduce valvetrain stress, thus increase engine efficiency and performance.

I thought I would throw the idea around for maybe a younger mind to pickup and maybe follow up on material advancements as well has newer engineering concepts.

We can always use a better spring design for many applications.
