Fuel injector for spraying fuel into a combustion chamber of an engine ignition control, method of spraying fuel and method of manufacture of an injector

摘要

"Fuel injector for an internal combustion engine.The present invention relates to a fuel injector comprising a head (13) having an external surface free (20) and a main orifice.Which is adapted for injecting a jet of fuel to a principal direction (P), and a second orifice (15) which is adapted to inject a jet according to a direction to an outer surface and communicate directly with an injection chamber (24).The secondary direction forms an angle of 100 to 800 198 with the principal direction so that the secondary jet (26) intersects the main jet (22) in a zone of rupture (30) which begins at a distance (d).
