Title:
TEMPERATURE PREDICTION DEVICE AND TEMPERATURE PREDICTION METHOD FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/216211
Kind Code:
A1
Abstract:
A temperature prediction device and a temperature prediction method for an internal combustion engine are configured to predict an initial temperature of the internal combustion engine on the basis of an intake pressure acquired as an outside air pressure at a timing within a period after the internal combustion engine is started from a stopped state and before the internal combustion engine starts rotating, an intake pressure acquired as an intake representative pressure at a timing within a period after the internal combustion engine starts rotating and before combustion starts inside a combustion chamber, and an internal combustion engine rotation number acquired at said timings, and are configured to predict a temperature of the internal combustion engine after the start of combustion, using the predicted initial temperature.
