METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for operating an internal combustion engine, which comprises a combustion motor (10), a fresh gas flow, an exhaust gas system, an exhaust gas turbocharger having a compressor (24) integrated in the fresh gas flow and a turbine (22) integrated in the exhaust gas system, and an additional, preferably electrically driven compressor (28) integrated in the fresh gas flow, wherein a scavenging is carried out in that, in the case of an over-pressure in the fresh gas flow downstream of the compressor (24) in comparison to the pressure in the exhaust gas system upstream of the turbine (22), a flushing of combustion gas present in the combustion chamber of the combustion motor occurs by a simultaneous opening of an inlet valve allocated to the combustion chamber and an outlet valve of the combustion motor (10) allocated to the combustion chamber, characterized in that, in the case of a load jump, the additional compressor (28) is first activated and then the scavenging is carried out by means of an additional opening of the inlet valve (18) during the outlet cycle via a switchable valve gear.
