Abstract
The fuel injection valve is constructed of a valve body and a single valve needle. The valve needle operates under the pressure of the fuel to move a first distance permitting injection of fuel through the bottom nozzle of the valve body into a combustion chamber and moves a greater distance to expose the remaining nozzles to inject additional fuel into the combustion chamber. The valve needle has a conical end face which sealingly engages a valve seat of the valve body disposed between the respective set of nozzles when in the closed position.
