Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2017190673
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine enabling both of an early rise of an exhaust gas temperature and suppression of fluctuation of axial torque.SOLUTION: A control device 70 for an internal combustion engine is applied to the internal combustion engine including: a supercharger 40; an oil supply device 60 for supplying lubrication oil between a shaft 45 of the supercharger 40 and floating metal serving as a bearing; a fuel injection valve 16; and an oxidation catalyst 29 and a DPF 30 serving as an exhaust emission control device. The control device 70 for the internal combustion engine includes: an injection valve control section 71; an injection amount setting section 72 for setting a base injection amount in accordance with an operating state of the internal combustion engine; a hydraulic control section 73; a hydraulic pressure setting section 74 for setting the base pressure of the lubrication oil; and an execution section 75 for executing exhaust temperature rise control for raising a temperature of exhaust gas flowing in the oxidation catalyst 29. In the exhaust temperature rise control, the execution section 75 makes a correction to increase the base injection amount set by the injection amount setting section 72, and makes a correction to increase the base hydraulic pressure set by the hydraulic pressure setting section 74.SELECTED DRAWING: Figure 1
