Verfahren zur Abgasnachbehandlung bei einem Verbrennungsmotor

摘要

The method involves providing multiple fuel injections and carrying out a secondary air injection in an internal combustion engine (1). The starting of the operation of the engine with the secondary air injection occurs in a time-delayed manner for starting the operation of the engine with multiple injections. An operation with a late angular ignition spacing occurs during the operation with multiple injections.
