Patent ID: 8186204

Claim:
A method for dynamically determining a usable injection range within a segment in which fuel can be injected into a cylinder of an internal combustion engine, wherein the segment is a crankshaft angular segment, wherein the segment is determined as a function of the number of cylinders of the internal combustion engine and from the number of banks, and wherein a plurality of cylinders into which the fuel is sequentially injected are preferably assigned to one bank, the method comprising the steps of: determining a possible injection range for the segment, arranging a usable injection range within which a fuel injection can be activated within the possible injection range, furthermore, determining an angular spread for a setup angle within the possible injection range as a function of a rotational speed gradient, making at least one of the possible injection range and the setup angle variable with respect to the relative position in relation to the crankshaft angle, and determining the usable injection range as a function of at least one operating parameter of the internal combustion engine.
