Abstract: A bypass conduit (23) connects an outlet passage of a compressor (21) of an exhaust gas turbocharger (20) and an inlet passage of an exhaust turbine (22), and a bypass valve (24) is provided therein. When the operating condition of a diesel engine (1) is found to be in a low-speed and high-load region, the bypass valve (24) is controlled by means of a valve controller to adjust the bypass conduit (23) so as to open it. Then, the charge air partly flows into an exhaust conduit (4) to increase the rotational speed of the exhaust turbine (22) and hence the charge air flow rate raises the output of the diesel engine (1). Additionally, as the charge air flow rate is increased, the operating condition of a compressor (21) is prevented from approaching the surging range.

Abstract: One of the swing shafts 32 of the nozzle vanes 31 is selected so as to operate as swing drive shaft 33 that projects to the outside. As the swing drive shaft 33 is driven to revolve, all the nozzle vanes 31 are driven to turn by a same angle by way of the driving lever 21 and the coupling ring 18 linked to it. Therefore, it is only the swing drive shaft 33 that projects to the outside, the projecting part can be sealed in a simple and reliable manner to improve the sealing effect and the durability of the variable geometry turbocharger. Additionally, since the rotary motion of the swing drive shaft 33 is directly used to driven the nozzle vanes 31 to swing, the mechanism for transmitting the driving force is simplified.
