摘要

The method involves determining an actual exhaust recycling rate (rAGR), and determining a nitrous oxide (NOx) reduction assigned to a recycling rate by a characteristic function. The function describes a global characteristic of the reduction that is attained by exhaust gas recycling. A weighing factor (GF) for the reduction is determined, where the factor depends on the reduction assigned to a reference value. An actual NOx emission is formed as a sum of an emission arising without exhaust gas recycling and a difference (NOxDiff) between two emission values multiplied by the factor. Independent claims are also included for the following: (1) a control device for controlling and regulating an operation of an internal combustion engine in particular diesel engine (2) a computer program for executing a method for determining nitrous oxide emission.
