ABSTRACT:
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.
