Title:
PISTON TEMPERATURE ESTIMATION DEVICE, PISTON TEMPERATURE CONTROL DEVICE, PISTON TEMPERATURE ESTIMATION METHOD, AND PISTON TEMPERATURE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/065095
Kind Code:
A1
Abstract:
Provided are a piston temperature estimation device, a piston temperature control device, a piston temperature estimation method, and a piston temperature control method with which the temperature of a piston can be appropriately estimated so that the life of the piston can be extended. A piston temperature estimation device (110) comprises a mouth temperature estimation unit (112) that estimates the temperature of a mouth part of a cavity of a piston, and an other-part temperature estimation unit (114) that estimates the temperature of another part on the basis of the temperature of the mouth part estimated by the mouth temperature estimation unit.
