Title:
CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/013814
Kind Code:
A1
Abstract:
When EGR begins in a supercharging region, the degree of opening of the wastegate valve (17) changes at a time T1 wherein the EGR rate changes at a first prescribed position due to the opening of the EGR control valve (21), and when EGR begins in a non-supercharging region, the degree of opening of the throttle valve (5) changes at a time T2 wherein the EGR rate changes at a second prescribed position due to the opening of the EGR control valve (21). Thus, it is possible to prevent a difference in torque level from occurring when EGR begins, regardless of whether the EGR begins in a supercharging region or a non-supercharging region.
