ABSTRACT:
A fuel injection system for an internal combustion engine has two intake valves for a combination chamber. The fuel injection system is comprised of a fuel injector installed in an intake manifold to supply fuel into the engine. The fuel injector is formed with at least two fuel discharge openings through which fuel sprays are ejected respectively toward the two intake valves. The fuel injector is further formed with at least one air discharge opening through which air is ejected at a high speed toward a position between the fuel sprays thereby to positively separate the fuel sprays from each other.
