Controlling internal combustion engine involves adapting parameter that influences integral of stoichiometric factor relative to estimate over period so actual lambda shift value is determined by integrating lambda control factor

摘要

The method involves determining a quantity of fuel to be supplied (MFF) to each cylinder depending on a load parameter, determining a corrected fuel value (MFFCOR) depending on the quantity to be supplied and a lambda control factor (LAMFAC), producing an injection valve control signal from the corrected fuel quantity, determining the lambda control factor with a lambda controller, determining an estimate of a stoichiometric factor and adapting a parameter that influences the integral of the stoichiometric factor relative to the estimate over a period so that an actual lambda shift value is determined by integrating the lambda control factor over a period related to the estimate and dividing the integral by the length of the period.
