FIELD: internal combustion engines.
SUBSTANCE: group of inventions relates to supercharging of an internal combustion engine. Essence of inventions consists in that supercharger (1) of wave supercharging system for compression of fresh air (2a) for internal combustion engine includes cold gas chamber (6), hot gas chamber (7), as well as rotor chamber (11) located between them, wherein rotor chamber (11) accommodating rotatable rotor (8) is arranged. Hot gas chamber (7) includes high pressure offgas channel (4) and low pressure offgas channel (5). Cold gas chamber (6) includes fresh air channel (2) and supercharging air channel (3). High-pressure flue gas channel (4), low-pressure flue channel (5), fresh air channel (2) and supercharging air channel (3) are connected to cellular rotor (8), wherein the hot gas chamber (7) includes first bearing (13) of the cellular rotor, and the cold gas chamber (6) includes second bearing (14) of the cellular rotor. Cellular rotor (8) includes shaft (12) of rotor, which rests on first and second bearings (13, 14), and hot gas chamber (7) includes heat exchanger (7c), made with possibility of cooling at least first bearing (13).
EFFECT: technical result is higher reliability and efficiency.
