Abstract

A fuel injector for supplying fuel to an air inlet duct of a spark ignition engine includes a plate valve member which is movable by magnetic forces away from a seating element on a seat member to allow fuel flow through an orifice to form a spray. The fuel spray flowing from the orifice flows into a bore in a tubular outlet and extending from the bore are at least two diverging bores from which two sprays of fuel are emitted, and air is introduced into the space between the orifice and the entrances to the diverging bores.
