Cross small-sized motor driven to rotate on the inside of external fixed cylinder, described rotation is except carbon cylinder by rotation along pitman shaft to flat
Move, described external fixed cylinder lower surface offers the external gas transmission connector being connected with inside external fixed cylinder, described
External gas transmission connector right-hand member is fixedly connected with appendix, and described rotation offers annular air scoop except carbon cylinder right-hand member, described
Rotation offer several ventholes being connected with air inlet except carbon cylinder medial surface.
Preferably, install for convenience, described gear height and micro-machine are highly identical.
Preferably, in order to reduce cost, the first described external screw thread driving face and the second external screw thread driving face length are identical.
Preferably, in order to lift intake efficiency, described external fixed cylinder inwall corresponds to external gas transmission connector position and consolidated
Surely it is connected with the L-type structure link for connecting external gas transmission connector and air inlet.
The invention has the advantages that the present invention novel self-cleaning fuel injector by micro-machine and gear come
Rotation is driven to be moved along connecting rod except carbon cylinder, while using appendix to supplying inside external gas transmission connector, then pass through company
Connect frame and air transferred into venthole from air inlet, so as to lift the air capacity on fuel injector surface, greatly promote internal oxygen density,
So that burning is more abundant, the generation probability of carbon distribution is reduced, and horizontal high voltage can also be entered to fuel injector surface except becoming silted up, is greatly promoted
Fuel injector surface cleanness, extend the service life and operating efficiency of fuel injector.
