ABSTRACT:
In an injection nozzle for an internal combustion engine including a nozzle housing, a closure member disposed in a nozzle opening and connected to a nozzle needle for axially moving the closure member outwardly off its seat in the nozzle opening to open the nozzle by providing a gap to permit fuel to be discharged into a combustion chamber of an internal combustion engine so as to form a fuel injection cone, the nozzle seal and the closure member have seal surface areas provided with turbulence chambers for imparting turbulence to the fuel flowing through the gap in order to more finely atomize the fuel forming the fuel cone in the combustion chamber.
