Abstract
A fuel injector and a method for manufacturing a fuel injector are described. The fuel injector includes a glass substrate and a nozzle enclosed within the glass substrate. The nozzle includes at least one injection hole. The method of manufacturing a fuel injector includes defining a shape of at least one injection hole in a glass substrate to obtain an at least one outlined injection hole and etching the at least one outlined injection hole to obtain the at least one injection hole.
Claims14
A fuel injector, comprising:
- a glass substrate with a transparent, amorphous bulk;
- and
- a nozzle defined by the glass substrate, the nozzle comprising an injection hole in the glass substrate;
- wherein the injection hole extends through the transparent, amorphous bulk from a first orifice in the transparent, amorphous bulk to a second orifice in the transparent, amorphous bulk;
- and
- wherein the injection hole has a cross-sectional shape that varies between the first orifice and the second orifice.

A fuel injector comprising:
- a glass substrate;
- a nozzle comprising an injection hole in the glass substrate;
- a light source to emit an optical signal;
- a fiber coupled to the light source to carry the optical signal;
- an optical wave-guide coupled to the fiber to guide the optical signal through the glass substrate toward the injection hole;
