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 cylinder portion is formed on the lower surface of a cylinder head constituting the combustion chamber or on the upper surface of the piston; An internal combustion engine, characterized in that a sliding member is disposed within the cylinder section, and at least during cold start, pressurized fluid is supplied into the cylinder section to move the sliding member and reduce the volume of the combustion chamber. 2. The piston includes a piston body and a cylinder member fixed to the piston body and having the cylinder part, and the sliding member is slidably installed in the cylinder part. The internal combustion engine according to paragraph 1. 3. The pressure fluid is lubricating oil for lubricating the internal combustion engine, and at least during cold start, the oil feed passage and the oil passage are brought into communication so that the oil in the oil reservoir flows into the oil feed device. Utility model registration claim 1, in which the oil in the cylinder part is supplied into the cylinder part by action, and on the other hand, after starting, the oil passage and the oil return passage are brought into communication, and the oil in the cylinder part is returned to the oil reservoir. or the internal combustion engine described in paragraph 2.
