Maybe we can use these. Apparently they are much faster so the dynamic
range is higher.

"Piezo injectors are just now coming to Europe on high-end vehicles from Range Rover, Audi and Mercedes-Benz. Piezo is widely seen as the next big evolution of the diesel engine.

Small crystalline discs in the injector change shape when electricity is applied. When the discs change shape, diesel fuel under high pressure is shot through a needle in a fine spray into the engine's combustion chambers.

As many as seven injections can be made in a single piston stroke, compared with one or three injections in most diesel engines. Those multiple injections lower the temperature in the combustion chamber, which in turn lowers oxides of nitrogen emissions.

Piezo injectors also reduce noise, vibration and smoke, all unpopular traits of a diesel engine."

"The piezo injectors to be used in the Super Duty pickups will be made by a joint-venture company in Blythewood, S.C., owned by German supplier Siemens VDO and International. Production of the injectors is scheduled to start in December,[2007?] said Siemens spokesman Brad Warner. He would not confirm any vehicle applications but said the plant's entire output will go to International."
