METHOD AND DEVICE FOR BURNING OFF THE SOOT accumulated in a soot filter of an air-compressing internal combustion engine

摘要

A process and a device for burning off the soot collected in a soot filter (5) of an internal-combustion engine (1) is proposed, in which the burning-off process is carried out without adversely affecting and influencing the operation of the internal-combustion engine (1). To this end, the burning-off process is carried out according to the invention exclusively during idling operation with the internal- combustion engine (1) running at an increased idling speed. IMAGE
