Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/034721
Kind Code:
A1
Abstract:
This internal combustion engine control device comprises an engine status estimation unit, a wall surface temperature estimation unit, and a manipulation amount calculation unit. The engine status estimation unit calculates the amount of energy transfer from a gas to a wall surface on the basis of parameters relating to an operating condition, parameters relating to a chemical condition of combustion, and parameters relating to an action status. The wall surface temperature estimation unit estimates the wall surface temperature on the basis of the amount of energy transfer from the gas to the wall surface. The manipulation amount calculation unit calculates, on the basis of the wall surface temperature estimated by the wall surface temperature estimation unit, the amount of manipulation of an actuator that is provided to the internal combustion engine.
