EINSPRITZDUESE FUER DIESELMOTOREN

摘要

The invention relates to an injection nozzle for the injection of a mixture or an emulsion of diesel fuel and water in diesel engines with a nozzle needle (8) arranged on a needle valve seat (16) of the nozzle body (2) and opening under the injection pressure, whereupon the additive fluid is metered into the diesel fuel in the region of the needle valve seat. A different additive from water may be mixed with the diesel fuel. The nozzle body consists of two components (1, 2) joined together, preferably by hard-soldering, the first of which (1) has the guide passage (19) for the needle (8) and the supply passages (3, 4) for the diesel fuel and additive and has a tubular attachment (7) which surrounds the needle (8) leaving a through-flow passage (9) for the diesel fuel, while the second component (2) has the needle valve seat (16) and surrounds the tubular attachment (7) of the first, leaving a through-flow passage (12) for the additive, whereby the passage (12) for the additive communicates with that (9) for the diesel fuel in the region of the needle valve seat (16). This facilitates manufacture of the nozzle.
