CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2012/066684
Kind Code:
A1
Abstract:
An engine system (1) is provided with an engine ECU (10), a shutoff valve (163) capable of shutting off an EGR passage (16), and a temperature sensor (42) for detecting the temperature of an exhaust gas purification device (30), and shuts off the EGR passage (16) by the shutoff valve (163) when the temperature of the exhaust gas purification device (30) is less than a predetermined threshold value. Further, the engine system (1) increases the fuel injection quantity of an injector (17) while decreasing the valve opening of a diesel throttle (19) in response to the increase of the quantity of flow of exhaust gas into a turbocharger (14) when the output of an engine (100) is less than a predetermined value. Meanwhile, when the output of the engine (100) is the predetermined value or more, the opening of a variable nozzle vane mechanism (141) of the turbocharger (14) is increased.
