CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

An engine system (1) comprises an engine ECU (10), an EGR passage(16) which allows an exhaust manihold (13) and a suction manihold (11) to communicate to each other, a shutoff valve (163) which can shutoff an exhaust gas inlet part of the EGR passage (16), and a diesel throttle (19), wherein the valve opening degree of the diesel throttle (19) is adjusted in accordance with the amount of sucked air while opening the shutoff valve (163) to open the EGR passage (16) during the performance of a regeneration treatment of an exhaust gas purification device (30). In addition, the engine system (1) can increase the opening degree of the EGR valve (162) upon the opening control of the shutoff valve (163) to increase the opening degree of a variable nozzle vane mechanism (141) of a turbocharge (14).
