Abstract:

In this paper one the ColdTest diagnosis method over internal combustion engine for quality tests at the end of the assembly-line will be considered as regarding the implementation of image matching correlation of visual dot patterns of vibration signals. Experiments were carry out in order to develop the visual method for fault diagnosis and monitoring under 5 different types of faults conditions: one inverted piston, one connected rod without half-bush, one discharge equalizer out of housing, counter rotating masses with a phase lag of 180 degrees, one tight oil pump screw.

Keywords:

ColdTest, visual dot pattern, matching.
