초록 ▼

A fuel injector system for a high speed, high pressure engine, the fuel injector system including a pressurized fuel supply, a fuel distributor with an electronically controlled and electronically monitored fuel metering mechanism and a fuel injector with an electronically monitored needle valve wherein the fuel system includes an electronic control module to receive signals from the positioning of the needle valve and the signals from the fuel metering mechanism for analysis and electronic regulation of the metering system to effect injection according to optimum operating conditions.

대표청구항 ▼

[ What is claimed is:] [1.] A fuel injector system with a plurality of fuel injector units, the injector system having electronically operated fuel delivery components for control of a fuel injection pulse to each injector unit comprising:an electronic control network having an electronic control module with memory means for mapping a reference operating profile for each injector unit and processing means for processing electronic sensor signals and controlling the electronically operated fuel delivery components; wherein each fuel injector unit has a fuel injector component and a hydraulic distributor component having electronically controlled valve means for regulated delivery of fuel to the injector component; wherein the injector component has an injector nozzle with a discharge tip with discharge orifices, a compression spring and a hydraulically actuated needle valve displaceable in the injector nozzle against the closure force of the compressing spring, the needle valve having sensor means for tracking the displacement and position of the needle valve, the sensor means having a transducer element on the needle valve displaceable with the needle valve and a stationary transducer element in the injector nozzle arranged in relation to the transducer element on the needle valve wherein the sensor means generates a continuous feed-back control signal indicative of the displacement and position of the needle valve in each injector unit that is processed by the electronic control module, wherein displacement and position of the needle is indicative of fuel discharge through the discharge orifices; wherein the electronically controlled valve means of the hydraulic distributor component has a displaceable slide valve and an electronically controlled displacement means for displacing the slide valve, the displacement means having position sensor means for sensing the position of the slide valve and providing a signal indicative of such position to the electronic control module for processing; and wherein each distributor component has independently operated electronic displacement means for regulating the distributor component valve means by the electronic control module with discrete adjustment for each injector unit from the processing of the feed-back control signal from the sensor means of the needle valve and the sensor means of displacement means in each injector unit, in accordance with the reference operating profile for that unit.
