Abstract: A liner mounting structure for measuring piston friction in which a liner is mounted in a cylinder block of an internal combustion engine and is cylindrically shaped to define a space in which a piston undergoes rectilinear motion. A protrusion is formed around an outer circumference of the liner at an upper portion of the liner. A combustion pressure passageway formed in the liner starting from an upper surface of the liner and extending downwardly to a bottom surface of the protrusion. An indentation is formed in the cylinder block corresponding to a position of the protrusion of the liner. An upper O-ring groove formed in the cylinder block above the indentation. A lower O-ring groove is formed in the cylinder block below the indentation, and a center O-ring groove is formed in the cylinder block within the indentation. An upper O-ring is mounted in the upper O-ring groove, a lower O-ring mounted in the lower O-ring groove, and a center O-ring is mounted in the center O-ring groove.
