Abstract: A method for adjusting correction values for metering fuel using at least one fuel injector, from a high-pressure accumulator into a combustion chamber of an internal combustion engine, using training and correction datasets. The method includes: in the correction dataset, adjusting the correction values based on training values of the training dataset, the correction value in each active neighboring field being adjusted based on a mean neighboring field training value, the correction value in each field of each field region that includes an active field being adjusted based on a mean field training value, wherein the correction value in each inactive field is adjusted based on a transfer training value, the transfer training value being determined according to at least one correlation rule, based on the training values of the active neighboring fields; and providing the correction map having the adjusted correction values for further use.

Abstract: A spray orifice disk for a valve for a flowing fluid and, in particular, for a metering or injection valve for an internal combustion engine, including a disk body and a spray orifice set-up, which is formed in the disk body and is configured with at least one spray orifice for dispensing supplied fluid, and including at least one channel for supplying the fluid to the spray orifice. The spray orifice, the channel and/or the transition between the channel and the spray orifice being configured to form a swirl geometry of the spray orifice disk in such a manner, that during operation, due to interaction of one or more jets of the fluid emerging from the spray orifice in turbulence atomization, an oval cross-sectional pattern of the spray is formed, in particular, in the form of a flat spray.

Abstract: A spray orifice disk for a valve for a flowing fluid and, in particular, for a metering or injection valve for an internal combustion engine, including a disk body and a spray orifice set-up, which is formed in the disk body and is configured with at least three spray orifices, each for dispensing supplied fluid. The spray orifices are being configured to form a swirl geometry of the spray orifice disk in such a manner that during operation, a combined spray is formed from at least three individual jets by interaction of a plurality of at least three individual jets of fluid emerging in atomized form from the spray orifices.
