できる。[Means 1 for solving the problems] In order to solve the above problems, the present invention provides grooves whose width becomes narrower in the depth direction on the sliding surface of the piston ring with the cylinder liner. The piston ring is fixed at the position of the scavenging hole, and the scavenging hole is inserted from the outside into the groove. It is characterized by detecting the amount of piston ring wear by inspecting or measuring its depth. Thereby, the wear amount of the piston ring can be detected without removing the piston.

とにより摩耗量が検知できるように構成している。2 is a cylinder liner, 3 is a piston, 4 is a piston ring, 2a is a scavenging hole, la is a manhole bored in the crankcase 1, and 5 is a manhole cover ν. As shown in FIG. 2, the piston ring 4 has an annular groove 6 on its outer peripheral surface (sliding surface with the cylinder liner 2) 4a.
is engraved. The depth ΔX of the groove 6 is determined to be a value equivalent to the limit wear amount of the ring 4. Further, the width B of the groove 6 is formed in a V-shape such that it decreases in the depth direction, that is, in the direction from the outer circumference to the inner circumference, so that the amount of wear can be detected by measuring the sound.

ことができる。In the internal combustion engine having the above configuration, the piston ring 4
To detect the entire amount of wear, stop the rotation of the engine crankshaft at the position where the piston ring 4 intersects the scavenging hole 2a, open the cover 5 of the manhole 1a, and open the scavenging hole 2a' from the manhole 1a. (Through z, measure the width B' of the groove 6 by visual inspection 2 mechanical, optical, electrical measurement, etc.) This allows the amount of wear on the piston ring 4 to be detected. disappears and ΔX=0, it can be considered that the piston ring 4 has reached its wear limit.

に低減され９機関の整備性が向上する。The present invention is constructed as described above, and 1. According to the method of the present invention, the amount of wear on the piston ring can be detected simply by inspecting or measuring the size of the groove carved on the outer circumferential surface of the piston ring. . Therefore, the wear amount of the piston ring can be detected while the piston is still installed in the engine, and the number of man-hours for inspecting the piston ring is greatly reduced compared to the conventional system, thereby improving the maintainability of the engine.
