Abstract
The injector comprises a body (1) with a tip (2) exhibiting at least one calibrated outlet hole for jets of fuel as well as a skirt (25) for dispersing the fuel received in the form of jets, the skirt (25) being tubular and extending the body (1) to which it is fixed by its upstream part (14), and its downstream part (26) is formed, at least toward the downstream end, by at least one lateral wall thinned to a bevel (28) of thickness decreasing toward the downstream end as far as its downstream free edge in the form of a thinned blade (29). For preference, a concave notch turned toward the downstream end is formed in the free edge of each bevel, and each jet (J1, J2) of fuel from the two-hole injector strikes a region (30) on the internal face of a lateral wall of the skirt. Application to injectors, particularly multi-hole injectors, for automobile engines.
