Document Type and Number:
WIPO Patent Application WO/2016/132457
Kind Code:
A1
Abstract:
The present invention provides a means for easily and accurately evaluating the state of wear of an engine cylinder liner. After a maintenance worker places an imaging device 14 on the upper surface of a piston 54, the piston 54 is made to move back and forth once within the cylinder 51. While the piston 54 is moving back and forth once, on the basis of crank angle data transmitted from a crank angle measurement device 8, a terminal device 11 transmits command data to the imaging device 14 when the imaging device 14 reaches a prescribed position in the movement direction of the piston 54. The imaging device 14 images the inside surface of the cylinder liner 53 and a fire-contacting surface of a cylinder cover 52 in accordance with the command data and transmits generated image data to the terminal device 11.
