Title:
COMPRESSED AIR PRODUCTION DEVICE, AND TURBOCHARGER AND INTERNAL COMBUSTION ENGINE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2016/181427
Kind Code:
A1
Abstract:
The purpose of the present invention is to increase the range of the amount of air flow in a low-flow-volume region and prevent a reduction in the range of the amount of air flow even in a high-flow-volume region. A turbocharger (10) is equipped with two air supply passages (51, 52) connected to an inlet of a compressor (30), and an air distribution means (70, 80) for distributing the air flowing in the two air supply passages (51, 52). The two air supply passages (51, 52) include a low-speed air supply passage (51), which has an inlet guide vane (IGV) (40) formed by arranging multiple vanes (41), and a high-speed air supply passage (52), which does not have an IVG. The air distribution means (70, 80) preferentially distributes the air flowing in the two air supply passages (51, 52) to the low-speed air supply passage (51) on a surge-region side, and preferentially distributes the air flowing in the two air supply passages to the high-speed air supply passage (52) on a choke-region side.
