Abstract
The vibration signals of healthy and faulty diesel engines were converted into symmetrized dot pattern (SDP) displays using Pickover’s method. The basic idea of the paper is to reveal how one of the parameters is influencing the final results. Experiments were carry out in order to evaluate the system 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.
