Abstract

This invention relates to an internal combustion engine, in particular of the self-igniting type, with a compressor, which is preferably connected to an exhaust gas turbine and is located in an intake flow passage for compression of the intake air, and with a charge air line leading to an intake manifold, the compressor operating independently of the engine, at least in the starting phase. To permit a quick and simple start-up of the engine at a low compression ratio the proposal is put forward that an air recirculation line controlled by a valve depart from the intake manifold, which opens into the intake flow passage upstream of the compressor, charge air line and air recirculation line forming a closed loop.
