Abstract:
A fuel injector is provided which includes a director, such as a ball, mounted downstream of the fuel injection port. When the valve is actuated, fuel exits the injection port. Fuel adheres to the ball until it reaches the equator of the ball. At the equator, the fuel begins to separate from the ball and forms a sheeted, cone-shaped configuration. When used with poppet valve injectors, the present invention preferably includes a wall manifold above the ball. Air from an air source, such as from the engine vacuum is introduced through the wall. Air travels through an air distribution chamber at a ninety degree angle to the direction of fuel flow. The air stream is directed to the balls equator. This blast of air causes the fuel to atomize to a droplet size in the range of 3 to 6 microns SMD. When the invention is used with solenoid actuated fuel injectors, a ball is mounted downstream of the director plate.
