    • A fuel injection, spark ignition, piston type internal combustion piston engine 1 with a fuel sprayer 2 comprising a hollow casing 3. A liquid fuel injector 4 is disposed within the upper end 5a of the hollow interior 5 of the casing 3, and comprises means for injecting liquid fuel into the hollow interior 5. Structure 6 is placed within the hollow interior 5 and is disposed in the path of fuel 7 injected, whereby injected fuel is temporarily deposited on the structure 6. A venturi-shaped passageway 8 enables the induction phase (stroke) of the engine 1 to remove the temporarily-deposited liquid fuel from the structure 6 and into the associated cylinder of the engine 1. The structure 6 comprises an inner body 10 of conical form disposed within an outer body 11 of annular form, so as to define an annular passageway 12 therewith. The sprayer 2 is located by a recessed 22 formed in the air inlet tract 34 of the engine 1. As the induction phase of the engine takes place, air is induced into the sprayer 2 through an auxiliary air duct 21 to remove the deposited fuel from the structure 6 and forms an air atomized spray 24 which then passes through the venturi-shaped passageway 8 where a further intermingling of air and fuel takes place.
