Abstract
Abstract A fuel injection nozzle for internal combustion engines has two hole circles with injection holes (12, 13) on its combustion chamber end. The injection nozzle in a nozzle body (10) has two coaxial valve needles (15, 16) for separate selection of the two hole circles. A separating sleeve (30), the face of which acts in concert with a valve seat (29) common to the two valve needles (15, 16), is arranged between the combustion chamber side end sections of the valve needles. The fuel injection nozzle is preferably suited to preinjection and main injection for large diesel engines. <IMAGE>
