The Diagnostic System of Piston Engines Based on Ununiformity in Speed

The work analyses the possibility to diagnose the overalloperation of the piston engine based on the crankshaft angularspeed. The testing was camed out on the basis of the mathematicalmodel-simulator of malfunctioning. The possibilityfor diagnostics based on the lack of uniformity of the crankshaftspeed has been confirmed and the continuation of experimentingin practice with the proposed method justified.
