Top feed disc injectors use a small disc with six holes around its circumference.
The disc rests on a short chimney that surrounds a metering hole.
As the disc is raised off the chimney by magnetic force, fuel flows through the holes in the disc, over the walls of the chimney, and out the metering hole to form a full, finely atomized cone.
