Abstract
Flanged onto the air casing (6) of a free-running pressure wave supercharger for an internal combustion engine is an electric motor (10a) whose shaft (28) is effectively connected to the rotor shaft (8) via a free-wheel overrunning clutch (9a) with engagement rollers (27) as the engagement bodies. In order to start a supercharged internal combustion engine, the electric motor (10a) accelerates the cell rotor (2) (in the case of a diesel engine, for example, during the short preheating period) to a rotational speed which ensures a functioning pressure wave process immediately after the diesel engine starts. The cell rotor (2) is then further accelerated by the exhaust gases of the diesel engine and then releases itself from the drive connection with the electric motor (10a), which has been put out of operation in the meantime.
