Yes Bob, The newest piezioelectric injectors will be capable of doing=20
exactly that. With a sofisticated enough EMS we could even run without=20
a throttle valve, but that is really for the future. I think Tracy's=20
system might even be able to fire the injector. I have an inquiry into=20
Siemens about the system. Used on the new gasoline Audis, and diesels=20
for several years.
