[MEANS] Providing a pressure gauge 7a to detect a scavenging pressure Ps within a scavenging trunk 6, a motor 8a to assist or dampen a driving of the turbocharger, a generator 8b to charge a power storage device 11 with a regenerated electric power of the motor 8a, and a control device 9. The control device 9 is provided with at least a scavenging pressure database 9a1, a target scavenging pressure calculating means 9a2 which computes a target scavenging pressure tPs, a pressure comparator 9a3 which compares the scavenging pressure Ps and the target scavenging pressure tPs, and a main control unit 9a4 which controls the motor 8a or the generator 8b in response to the comparison results produced by the pressure comparator 9a3. [ADVANTAGEOUS EFFECTS] The entire amount of exhaust gas is continuously treated so as to be purified. The energy of the exhaust gas can be effectively utilized as a driving power for the motor, without loss.",
