ALGORITHMIC PROVISION OF MONITORING OF IDENTITY OF CYLINDER POWERS OF POWER UNITS ON THE BASIS OF PROCESSING OF DIRECT INDIRECT DATA

A frequency-modulated instantaneous crankshaft speed signal is proposed as input information for monitoring the identity of cylinder power an internal combustion engine. Algorithmic software based on solving a predefined system linear algebraic equations with optimization solution least-squares method. Frequency and time methods measurement research are investigated. In temporal representation, balance between values fluctuation first mass at specific points in sum calculated contributions cylinders. The addition to determined by product weights corresponding function contribution signal. This convolution interval torque individual its transfer function. As result equations, we obtain cylinders, which used determine distribution unit. When comparing methods, it was found that method presentation provides better performance. mathematical apparatus estimating maximum plausibility parameters components cylinders fluctuations rotation has been developed. An algorithm implements correlation analysis, also proposed. significant improvement signal-to-noise ratio implementation crankshaft. analytical expression cross-correlation realization obtained. scheme cylindrical powers unit uncertainty technology processing indirect data investigated requirements metrological characteristics hardware measuring established.
