Japanese Patent JP2023112486
Kind Code:
A
Abstract:
To accurately calculate a wall surface temperature of a cylinder bore.SOLUTION: A control device 100 executes processing of: acquiring a flow rate of cooling water flowing in a water jacket 70 provided in a cylinder block 2 of an internal combustion engine 1; acquiring a cooling water temperature that is a temperature of cooling water; calculating heat generation amount when fuel supplied into a cylinder of the internal combustion engine 1 is burned; and calculating a wall surface temperature of a cylinder bore 4b of the internal combustion engine 1 on the basis of the flow rate of the cooling water, the cooling water temperature and the heat generation amount when the fuel is burned.SELECTED DRAWING: Figure 1
