The JI injector is a production Gasoline Direct Injection
(GDI) piezo injector permitting with CNG
of reduced pressure the injection of the amount of
fuel needed to work locally stoichiometric in the
pre-chamber. The DI injector is a prototype CNG
solenoid high pressure delivering the large volumes
of CNG injected at up to 300 bar, also proved eective
in working with hydrogen.
