Abstract (en)

Injector in which an obturator element (11) controlled by an electromagnetic actuator (7) controls the formation of at least one jet of fuel (15) through an atomization hole (14), characterized in that it is provided with auxiliary atomization means including at least one surface (21) arranged so as to be transversely oblique with respect to the said jet of fuel (15), at a predetermined and relatively large distance from the atomization hole (14) with respect to the jet diameter, such that the surface (21) is struck by the jet at a predetermined point (22) with an angle of impact other than 0 DEG and 90 DEG , and including moreover a duct (25) for a jet of auxiliary air (23) oriented so as to direct the jet of air (23) against the said oblique surface (21), substantially at the point of impact (22) thereon of the said jet of fuel (15). <IMAGE> <IMAGE>
