Abstract

An electromagnetic fuel injector (30) has a tubular non-magnetic body (32) defined by radially inner and outer side walls (34, 36) bounding an annular shaped interior which contains a tubular solenoid coil (54) and an annular valve element (56) that is operated by said solenoid coil (54) to open and close the fuel injector (30). The radially inner wall (34) bounds a central through-hole in the body (32) that allows the stem (24) of an engine intake valve (18) to pass through the fuel injector (30), thereby enabling the fuel injector (30) to be mounted on the manifold (12) directly over the valve head (22).
