Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/003806
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel internal combustion engine control device with which the EGR rate during a transient state can be estimated accurately. For this purpose, according to the present invention: a reference space of an intake passageway is divided into a plurality of unit spaces USu, USd along a flow line of a flow of a mixture gas of intake air and EGR gas; a physical model based on an advection equation for estimating the EGR rate of the mixture gas in correspondence to the respective unit spaces USu, USd is constructed; and, using the physical model, the EGR rates of unit spaces continuous with the unit spaces USu, USd at the head are estimated in order from the unit spaces USu, USd, thus estimating an EGR rate of a flow into a combustion chamber.
