ABSTRACT:
A supercharged internal combustion engine for a drive system of land vehicle with an air filter (18) and a charging air manifold (12) connected with each other by several flow paths (21, 22, 23) for the combustion air. Each flow path (21, 22, 23) is equipped with a check valve (19, 36, 26) while the flow path (22) is additionally equipped with a controllable closure device (20) and the flow paths (22, 23) are equipped with one charging air compressor (27, 31) each. The charging air compressor (27) includes a drive by an exhaust gas turbine (28). The charging air compressor (31) is driven by an electric motor (32) with permanent magnet energization, whereby the energy for feeding the electric motor (32) is supplied by a generator (33) energized by permanent magnet and driven by the internal combustion engine (11). Depending on the operating condition of the internal combustion engine (11), one of the flow paths or several flow paths are simultaneously in operation. Especially during acceleration operations, an optimal supply with combustion air is achieved thereby. Since the charging air compressors (27, 31) are operated by energy of the internal combustion engine (11), the availability of the energy for the drive of the charging air compressors (27, 31) corresponds to the operating capability of the internal combustion engine (11).
