Internal combustion engine i.e. Otto-engine, operating method for automobile, involves supplying charge air flow to combustion chamber of Otto engine in flow direction of charge air flow before compressor of turbocharger
The method involves removing an exhaust gas partial flow from an exhaust gas flow of an Otto engine (12) in a flow direction of the exhaust gas flow behind a turbine (36) of an exhaust gas turbocharger (24) and an exhaust gas catalytic converter (54). A charge air flow is supplied to a combustion chamber of the Otto engine in a flow direction of the charge air flow before a compressor (22) of the turbocharger. The exhaust gas partial flow is separated into two partial flows, which are adjusted depending upon a charge air temperature. An independent claim is also included for an internal combustion engine arrangement.
