Abstract

The present invention pertains to a direct injection inwardly opening „differential valve type nozzle" based liquid or gaseuous fuel injector of improved speed and frequency of operation by use of an ultra low inertia valve closer unit 10 („needle") of benefit but not limited to, popular VCO and SAC nozzle type fuel injectors piezoelectrically operated from a fuel rail source. High-speed operation with negligible fuel leakage return flow of said nozzle benefits by being driven by the high-speed outward opening piezoelectric metering valve unit 29, wherein return flow may be eliminated entirely by application of a venturi preferably inside the fuel injector, within its valve needle tip. Enables concurrent fluid injection of any gas or liquid, eg. LNG, diesel, and water per cycle.
