Title:
CONTROL METHOD AND CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/047286
Kind Code:
A1
Abstract:
In the present invention, a negative pressure control valve (44) is provided in an air intake passage (12) on the upstream side of a confluence position (30) where an exhaust gas recirculation (EGR) passage (27) converges with the air intake passage (12). In an EGR region (Regr) where EGR gas recirculates through the EGR passage (27) into the air intake passage (12), the negative pressure control valve (44) is controlled so as to ensure a pressure difference between an exhaust passage (13) and the intake passage (12). In an operating region (R2) on the negative-load side of the EGR region (Regr), the negative pressure control valve (R2) is controlled in the closing direction so as to suppress noise generation.
