Abstract
A fuel injection feedback system comprises a light source disposed inside a fuel injector, an optical sensor disposed inside the fuel injector, and a computing device electronically connected to the optical sensor. The light source is a device configured to emit light capable of being reflected by cavitation. The light source could be disposed on or within the needle or nozzle of the fuel injector, or at a variety of other locations inside the fuel injector. The optical sensor is configured to detect an intensity of light caused by receiving light reflected from cavitation occurring inside the fuel injector.

A method of obtaining feedback from a fuel injector in a combustion engine, the method comprising the steps of:
- receiving, via an optical sensor disposed inside the fuel injector, light reflected from cavitation;
- determining a start time of a fuel injection pulse by detecting the occurrence of a disturbance in the intensity of light reflected by the cavitation and received by the optical sensor;
- determining a stop time of the injection pulse by detecting the disappearance of the disturbance in the intensity of light reflected by the cavitation and received by the optical sensor;
- and
- determining the duration of the injection pulse by using a computational device to compare the time difference between said stop time and said start time.
A method of obtaining feedback from a fuel injector in a combustion engine, the method comprising the steps of:
- installing an optical sensor inside the fuel injector;
- configuring the optical sensor to receive light reflected from cavitation;
- and
- configuring the optical sensor for communication with a computational device for detecting a disturbance in the intensity of light received by the optical sensor.
A method of obtaining feedback from a fuel injector in a combustion engine, the method comprising the steps of:
- installing a light source inside the fuel injector;
- configuring the light source to direct light toward cavitation such that the light is reflected by the cavitation;
- installing an optical sensor inside the fuel injector;
- and
- configuring the optical sensor to receive light that is directed from the light source and reflected by the cavitation.
