Abstract
A very low pressure fuel injection system uses an engine driven mechanical fuel pump to supply fuel at low pressure to a fuel devaporizing chamber normally filled with liquid fuel and in which is immersed the body portion of an electronically opened fuel injector positioned to spray fuel axially into the upper end of the induction passage of an air throttling body, the chamber containing a fuel pressure accumulator and a fuel pressure regulator maintaining the fuel pressure at a level slightly below the pump delivery pressure and at the injection level, the fuel chamber being rapidly purged of vapors during engine cranking and running operations.
