Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2013/077155
Kind Code:
A1
Abstract:
The present invention addresses the problem wherein the amount of exhaust gas temporarily increases during deceleration driving and the amount of exhaust gas cannot be guided to the target value in a stable manner due to, for example, the length of the passage from the convergence area of EGR and new air to the cylinder, and the opening of an air bypass valve in an air bypass passage connecting the top and the bottom of the compressor during deceleration. In the present invention, in an internal combustion engine wherein exhaust gas is shunted from the downstream part of a turbine and recirculated to the upstream part of a compressor, when deceleration driving occurs and exhaust gas is being recirculated in the supercharging state, an air bypass valve which bypasses the compressor is closed, and a wastegate valve which bypasses the turbine is opened.
