Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/203798
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce fuel consumption by making a correction per cycle upon predicting a change in combustion limit caused by cycle-to-cycle variation in temperature and EGR rate. To this end, the internal combustion engine control device for controlling an internal combustion engine comprising a cylinder and an exhaust pipe is characterized by comprising a control unit which performs EGR control for returning exhaust gas in the exhaust pipe into the cylinder, whereby the control unit obtains an in-cylinder gas temperature and an EGR rate in a state in which both an intake valve and an exhaust valve are closed in a combustion cycle, and corrects a combustion parameter to be used in the same combustion cycle as the aforementioned combustion cycle on the basis of the obtained gas temperature and the EGR rate.
