Simple and inexpensive method of making quartz injectors yields injectors of superior characteristics. Quartz injector is fabricated by heating quartz rod and blowing and forming sphere on end. As with metal injectors, orifices are then drilled in spherical shell. Time required to form quartz is only 0.5 man-hour and 7.5 man-hours are required to drill holes. Total time of fabrication, 8 man-hours, is fraction of 40 man-hours required to complete metal injector. Success with technique and material is such that further substitutions for other related components are being contemplated.
