In a method for controlling an internal combustion engine, in particular a diesel internal combustion engine, at least one variable is formed on a cylinder-specific basis, which variable characterizes a respective profile of a combustion in an associated combustion chamber, and the control of cylinder-specific fuel injection parameters is influenced as a function of said at least one variable which characterizes the combustion profile.

In a method and apparatus for the cylinder-specific determination and control of a fuel injection quantity for a multi-cylinder internal combustion engine, the exhaust gas pressures of the cylinders of the internal combustion engine is recorded on a time-resolved, i.e. crankshaft angle-resolved, basis, and an exhaust gas pressure is calculated therefrom individually for each cylinder and used to determine the fuel quantity injected into the corresponding cylinder. In a comparison with a desired value the cylinder-specific actual fuel injection quantity error is then determined and used to set a corrected quantity of fuel to be injected into the corresponding cylinder.

A method for processing a sound signal y in which redundancy, consisting mainly of almost repetitions of signal profiles, is detected and correlations between the signal profiles are determined within segments of the sound signal. Correlated signal components are allocated to a power component and uncorrelated signal components to a noise component of the sound signal. The correlations between the signal profiles are determined by methods of nonlinear noise reduction in deterministic systems in reconstructed vector spaces based on the time domain.
