Abstract
The invention concerns a supercharged internal combustion engine in which two inlet ducts, which can be closed by inlet valves and whose flows are separated from one another, and two exhaust ducts which can be closed by exhaust valves enter the combustion space of a cylinder, one inlet duct and one exhaust duct being associated with one exhaust gas turbocharger. In order to achieve both a rapid build-up of supercharge pressure in the case of positive load changes and also an optimum homogenization of the mixture in the combustion space, the two exhaust ducts are also arranged so that their flows are separated and the inlet and exhaust side connected to the same exhaust gas turbocharger can be closed by one shut-off element each.
