Beschreibung
Zusammenfassung:	The engine has an exhaust gas turbocharger with turbine and compressor, a fan for feeding additional air into a connecting tube between a cylinder head and the turbine, a catalyzer, an exhaust gas feedback device and a fuel injection system with adjustable injection time/quantity. The fan sucks the air from the induction flow downstream of the compressor and the catalyzer is arranged upstream of the turbine. The catalyzer is electrically heated. The engine has an exhaust gas turbocharger with a turbine (2a) and a compressor (2b), a fan (3) for feeding additional air into a connecting tube between a cylinder head and the turbocharger's turbine, a catalyzer (6) for treating exhaust gas, an exhaust gas feedback device and a fuel injection system whose injection time and quantity are variably adjustable. The fan sucks the air from the induction flow downstream of the compressor and the catalyzer is arranged upstream of the turbine. The catalyzer is electrically heated. An Independent claim is also included for a method of operating the above internal combustion engine. Die Erfindung betrifft eine luftverdichtende, selbstzündende Brennkraftmaschine mit einem Abgasturbolader mit Turbine und Verdichter, einem Gebläse zum Zuführen von zusätzlicher Luft in ein Verbindungsrohr zwischen einem Zylinderkopf und der Turbine des Abgasturboladers, mit einem Katalysator zur Abgasnachbehandlung, einer Vorrichtung zur Abgasrückführung und mit einem Kraftstoffeinspritzsystem, dessen Einspritzzeit und -menge variabel einstellbar ist, wobei das Gebläse die Luft aus dem Ansaugluftstrom stromab des Verdichters ansaugt und wobei der Katalysator stromauf der Turbine angeordnet ist.
