The paper presents an innovative method for assessing technical condition of a marine diesel engine that drives synchronous genera-tor. It is based on the measurement and analysis of generator's phase-to-phase voltage. Additionally, it requires the measurement of a pseudoperiodic signal [3] with a period equal to duration of engine's working cycle. The basis for developing method was the assumption that rotational speed fluctuations of an engine’s crankshaft (and also the generator) depend on a course of a working process carried out in it. The generator's phase-to-phase voltage is directly dependent on a rotational speed fluctuation of its rotor. It must therefore be possible to assess a course of a working process of an engine based on a voltage waveform of a synchronous generator that cooperates together.
