CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

The engine system 1 includes: an engine ECU 10; an EGR path 16 communicating an exhaust manifold 13 with an intake manifold 11; an isolation valve 163 is capable of closing an exhaust gas inlet portion of the EGR path 16; and a diesel throttle 19, wherein the opening degree of the diesel throttle 19 is adjusted, when the isolation valve 163 opens the EGR path 16 while the regeneration process of an exhaust purification device 30 is performed. Further, the engine system 1 increases the opening degree of the EGR valve 162 and the opening degree of a variable nozzle vane mechanism 141 of a turbocharger 14 while performing the opening control of the isolation valve 163.
