Document Type and Number:
WIPO Patent Application WO/2019/124431
Kind Code:
A1
Abstract:
Provided is a compression-end pressure control device (300) for controlling the supply amount of a working fluid in a variable compression device which increases the compression ratio of a combustion chamber (R1) as a result of a working fluid having an increased pressure being supplied to a fluid chamber (R3), the compression-end pressure control device comprising: a compression ratio setting unit (305) which, when a compression-end pressure in the combustion chamber (R1) is higher than a predetermined reference range, controls the variable compression device to reduce the compression ratio of the combustion chamber (R1); and a variable compression device adjustment unit (306) which controls the supply amount of the working fluid on the basis of the compression ratio determined by the compression ratio setting unit (305).
