Abstract (en)
[origin: US7237527B2] A fuel injector comprising a head which has a free outer face and a main orifice designed to spray a fuel jet in a main direction and a secondary orifice designed to spray a fuel jet in a secondary direction, the main and secondary orifices opening into the outer face and communicating directly with a common injection chamber which is selectively placed in communication with a supply chamber. The secondary direction forms an angle alpha between 10° and 80°, with the main direction so that the secondary jet intercepts the main jet in a burst zone which starts at a distance d of between 1 and 15 mm, and the flow rate of the secondary jet is between 80% and 100% of the flow rate of the main jet. The invention also relates to a spark ignition engine and to a method of manufacturing the injector.
