We will investigate the way of the estimation of diesel generators technical condition by definition variation degree of the motor shaft rotational speed. I suggest to deactivate cylinders in a multi-cylinder motor one by one for eliminating methodological component of the error estimation results. Also I propose to take into consideration torsional vibrations of the shaft for reducing instrumental component errors in determining the degree of uneven.
Keywords: degree of irregularity of shaft rotating speed, assessment of technical condition in operation, eliminating the measurement error effect
