Title:
CONTROLLER OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2019100216
Kind Code:
A
Abstract:
To provide a controller of an internal combustion engine capable of suppressing surging.SOLUTION: A CPU 52 is configured to, in a case where there is a request for reducing opening of a throttle valve 16 in fuel cutting, calculate a pressure ratio Pr obtained by dividing supercharging pressure Pin by atmospheric pressure Pair. The CPU 52 is configured to, when the pressure ratio Pr exceeds a threshold, make processing of reducing the opening of the throttle valve 16 wait, make valve opening timing of a suction valve 18 advance, and enlarge opening of a WGV 34. The CPU 52 is configured to, in a case where the pressure ratio Pr is equal to or less than the threshold, execute control depending on the request for reducing the opening of the throttle valve 16.SELECTED DRAWING: Figure 1
