Abstract

The multi-cylinder engine has an exhaust gas feedback (3). The exhaust gas from and dispensing cylinder (2) goes to the feedback, to an exhaust gas collection line (10). there are at least two different turbine surfaces to which exhaust gas is supplied in two different conditions under partial load, in which case one of the other cylinders (1) is also brought into the process.
