ABSTRACT:
An internal combustion engine includes an intake manifold in a fresh air system. The intake manifold opens into inlet ports of a cylinder head. An exhaust-gas turbocharger has a turbine and a compressor, which is driven by the turbine. The turbine is disposed in the exhaust-gas system. The compressor is disposed in the fresh air system. The turbine has a turbine wheel and a wastegate channel configured to allow a bypassing flow of exhaust-gas past the turbine wheel of the turbine. A wastegate valve is disposed in the wastegate channel for selectively opening and closing the wastegate channel. An electric actuator is provided for operating the wastegate valve. A charge-air cooler is disposed, downstream of the compressor, in the fresh air system. The charge-air cooler is integrated into the intake manifold and is embodied with a water-cooled heat exchanger.
