ABSTRACT:
A fuel delivery injector for an internal combustion engine is provided. A fuel injector forms part of a device which provides a combined injection and ignition. The fuel delivery injector comprises first and second portions adapted to be detachably connected together. The first portion incorporates a valve structure having a valve member movable with respect to a valve seat for opening and closing a delivery port, and an actuating member operatively connected to the valve member. An actuator is provided in the second portion. When the first and second portions are connected together, the actuator is operably associated with the actuating member to provide an actuating assembly. Typically, the actuating assembly comprises an electromagnetic device in which the actuating member comprises a solenoid armature and the actuator comprises a solenoid coil, whereby connection of the first and second portions together completes assembly of the electromagnetic device.
