Claims

[Claims for Utility Model Registration] A cylinder liner, a piston slidably housed within the cylinder liner, and a cylinder having a protuberance disposed on the top surface of the piston of the cylinder liner and protruding into the cylinder liner. an annular groove formed on either the outer circumferential surface of the raised portion of the cylinder head or the inner circumferential surface of the cylinder liner; and an inner circumference of the cylinder liner provided in the annular groove and facing the annular groove. An O-ring that isolates the combustion chamber formed between the cylinder head and the top surface of the piston from the outside by contacting the surface or the outer circumferential surface of the raised part of the cylinder head, and the above-mentioned measuring engine. A measurement engine characterized in that the surface in contact with the O-ring is tapered.
