ABSTRACT:
A piston internal combustion engine in which for the engagement and disengagement of an exhaust gas turbocharger (12), its exhaust gas closure device (33) is opened, respectively, closed only so far that the charging air pressure produced by the continuously engaged exhaust gas turbocharger (11) remains approximately constant. By re-routing a small air quantity by way of a by-pass line (36) to the suction side of the compressor (24), the power input of the compressors (21 and 24) is kept small. During the engagement of the exhaust gas turbocharger (12), a small energy quantity is therefore sufficient in order to accelerate the same to its operating rotational speed. Thereafter, the engaging operation is terminated by complete opening of the exhaust gas closure device (33) and by opening of the charging air closure device (34).
