ABSTRACT:
An injection nozzle comprises: a nozzle body arranged in a case in such a manner that the nozzle body is movable along the axis thereof; an injection outlet for jetting fuel when said nozzle body is moved along the axis to open the injection outlet; at least one fluid jetting outlet which is communicated through a fluid supply passage to a fluid supply device, for jetting fluid towards the fuel thus jetted; and a control unit having at least one stationary opening and a movable opening to supply fluid to the fluid jetting outlet when the stationary and movable openings are aligned with each other, to thereby control fluid jetted from the fluid jetting outlet. The fluid jetted from the fluid jetting outlet is applied to the fuel jetted by the injection outlet, to cause the kinetic energy of the fluid to shear the fuel and to thereby improve the atomization of fuel, and to control a fuel scattering direction and a fuel spray pattern.
