SYSTEM AND METHOD FOR EXAMINING CYLINDER LINER, HOLDING TOOL FOR IMAGING DEVICE, AND CYLINDER LINER

摘要

The present invention provides a meansfor easilyand accuxately evaluating the state of wear of anengine cylinder liner. After a maintenance worker places an imaging device 14 on the upper surface of a piston 54, the piston 54 is caused 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 preseribed position in themovement direction of the piston 54. The imaging device 14 images the inside surface of the cylinder liner 53 and a flame-contact surface of a cylinder cover 52 in accordance with the command data and transmits generatedimage data to the terminal device 11.
