Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/136291
Kind Code:
A1
Abstract:
An internal combustion engine provided with a supercharger, an EGR device, and an intake air cooling device wherein, when the operation range has transitioned from an EGR stop range to an EGR implementation range, EGR control can be quickly started while suppressing the development of condensed water in intake air, thereby ensuring good fuel economy. A control device 1 for an internal combustion engine 3 is provided with an ECU 2. When the operation range of the internal combustion engine 3 is in an EGR implementation range B, the ECU 2 implements EGR control (step 2) and also implements a first water temperature control for controlling an intercooler (IC) water temperature TWic so that the temperature of the intake air passing an intercooler 32 exceeds a dew-point temperature (step 14). When the operation range of the internal combustion engine 3 is in an EGR stop range C, a second water temperature control for controlling the IC water temperature TWic is implemented so that, assuming that the operation range of the internal combustion engine 3 has transitioned to the EGR implementation range B, the temperature of the intake air that has passed the intercooler 32 exceeds the dew-point temperature (step 17).
