Title:
SUPERCHARGING SYSTEM OF INTERNAL-COMBUSTION ENGINE AND METHOD FOR CONTROLLING SUPERCHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/129036
Kind Code:
A1
Abstract:
A supercharging system of an internal-combustion engine provided with a plurality of turbo superchargers is provided with: a status amount detection unit that detects a status amount regarding an operation status of the internal-combustion engine; and a control unit that controls at least one of an intake channel switch valve and an exhaust channel switch valve so that a first operation mode transitions to a second operation mode when the status amount becomes greater than or equal to a threshold that is selected corresponding to the status amount on the basis of a first threshold function, and so that the second operation mode transitions to the first operation mode when the status amount becomes less than a threshold that is selected corresponding to the status amount on the basis of a second threshold function. The first threshold function and the second threshold function are set to be different from each other.
