The Cummins High Pressure Injector, U.S. Patent
#5,626,325 (May 6, 1997) implies that they are
looking to use such a beast.

Too Complicated, My Compression Actuated Injector and the GM compresion
actuated injectors that reference my patent are still not as simple as the
electromagnetic injectors.

Before going that route I'd start looking at
electrostrictive designs using piezo-electrics
or such. But that is why I'm checking out this list. Thot I might learn
something, and I am.

LOL. Better at what?   :-)
