Abstract
A fuel injector for an internal combustion engine is disclosed. The fuel injector includes a tip in fluid connection with a combustion chamber of the engine and includes an orifice for injecting fuel as a fuel jet. The fuel injector includes a protruding member in fluid connection with the first orifice extending from the tip at a protruding angle. The orifice injects the fuel jet into the first protruding member. The fuel injector includes a plurality of extension members in fluid connection with the protruding member and includes at least, a first extension member and a second extension member. The first and second extension members may extend from the protruding member at extension angles. The fuel jet may be distributed into, at least, a first distributed jet and a second distributed jet when the first fuel jet flows from the protruding member to the first plurality of extension members.
