記載の内燃機関。[Claims for Utility Model Registration] 1. In an internal combustion engine in which fuel in a combustion chamber is ignited by the compression action of a piston, a flexible bellows member is provided on the lower surface of a cylinder head constituting the combustion chamber or on the upper surface of the piston. , and at least 1″ inside the bellows member during cold start.
An internal combustion engine characterized by: supplying pressurized fluid to expand the bellows member and reduce the volume of the combustion chamber. 2. The internal combustion engine according to claim 1, wherein a recess is formed in the upper surface of the piston, and the bellows member is telescopically disposed within the recess. 3. The pressure fluid is lubricant oil for lubricating the internal combustion engine, and at least during cold start, the oil supply passage and the oil passage are communicated, and the oil in the oil reservoir is supplied to the oil supply device. Claims for registration of a utility model, in which the oil in the bellows member is supplied into the bellows member by the action of the bellows member, and after startup, the oil passage and the oil return passage are brought into communication with each other, so that the oil in the bellows member is returned to the oil reservoir. The internal combustion engine according to item 1 or 2.
