Abstract
In a method for operating a supercharged internal combustion engine of a motor vehicle, at the same time an internal exhaust gas recirculation and an external exhaust gas recirculation are carried out in an engine operating range with lean burn operation modes, wherein the exhaust gas recirculation rate of the internal and the external exhaust gas recirculation is increased with increasing load and/or speed of the internal combustion engine in the lean engine operating range and, at high engine speeds and loads, a homogenous mixture operation is carried out. The invention also reside in an internal combustion engine for performing the method.
