The existing state of the art in solenoid operated injectors technology promotes their use mainly for gasoline manifold injection in spark ignition engines. The attempts to use such injectors for direct fuel injection are hampered by slower and less repeatable dynamic response, as compared with hydraulically or mechanically operated diesel injectors. Also, the impact of the solenoid overheating and the resulting loss of power, is considered detrimental for such injectors when installed in the cylinder head of an engine. The next (third) generation of solenoid operated injectors is dealing with all these disadvantages. First, it is using a special inductive driving circuit for the solenoid to boost the opening of the injector needle by amplifying the supply voltage, but only for a very short instant of time.
