ABSTRACT:
The tubular skirt (12) in the partition between the air ports (2, 3) supports the injector (11) and forms two fuel passages (19) emerging in the ports (2, 3) between two opposed lateral walls (15) each thinned to a bevel (16) toward the downstream end with a free edge (17) in the form of a thin blade and with a notch having concavity turned toward the downstream end, a region (23) of the internal face of each lateral wall (15) upstream of the bevel (16) preferably being struck by at least one jet of fuel coming from the injector (11).
Application to fuel-injected engines with two inlet valves per cylinder.
