Control device on an air-compressing injection internal combustion engine for the regeneration of a soot burn-off filter

摘要

The invention relates to a control device on an air-compressing injection internal combustion engine for the regeneration of a particle burn-off filter. In order to achieve the exhaust temperature necessary for soot burn-off filter regeneration, even at relatively low load and low speed, an air-exhaust gas heat exchanger is arranged downstream of the soot burn-off filter, through which heat exchanger all or some of the aspirated fresh air flows, as a function of the position of a control element arranged in the intake pipe.
