Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2018145845
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To secure necessary intake air amount even when a bypass valve is fixed on a valve closing side by controlling an opening of a throttle valve and supercharging amount obtained by an electric supercharger while suppressing increase in the number of manhours adaptable to control.SOLUTION: An electric supercharger is disposed in an intake passage of an internal combustion engine, and a bypass passage for bypassing the electric supercharger is installed in parallel with the intake passage. A bypass valve is disposed in the bypass passage, and a throttle valve is disposed downstream of a connection portion with the bypass passage in the intake passage. When detecting that the bypass valve is fixed on the valve closing side, the control device is configured to operate the electric supercharger so that pressure of a portion in the intake passage upstream of the throttle valve and downstream of the electric supercharger and the bypass valve reaches target pressure that is pressure when the bypass valve is not fixed on the valve closing side.SELECTED DRAWING: Figure 4
