Abstract
An injector for injecting fuel for an engine, which injector comprises a nozzle, a fuel injection orifice in the nozzle, a valve for closing the orifice, a vibratory device for vibrating the nozzle to cause the valve to move away from the orifice to allow fuel to be injected, and a stop device for limiting the travel of the valve away from the orifice, the stop device being movable whereby during use of the fuel injector the injected fuel for the engine can be varied to suit the engine requirements at any given time by moving the stop device so as to control the travel of the valve injection rate through the orifice.
