A method is provided for improved diagnostics of an internal combustion engine that includes cylinders, a crankshaft, crankshaft rotation angle sensor (CRAS), a vibro-sensor, a logic-mark sensor, each sensor produces respective signals. The method contemplates -receiving the signals -dividing them into a plurality of idling cycles, -determining the crankshaft's position based on stochastic filtration, quasicontinuous representation of the signal, the Kalman filter, a nonlinear stochastic filter, based on CRAS characteristics and quasicontinuous representation, - determining the Riesz generator basis function based on technical characteristics of the vibro-sensor, -secondary discreeting of the signals with a replacement of argument, -discreeting of a reciprocal function, -obtaining a discrete wavelet transform, -obtaining a continuous wavelet transform,; -obtaining a discrete wavelet transform of a reciprocal function, and - producing output data. Two-dimensional arrays are divided relatively to predetermined indexes in the discrete transforms, an empirical probability distribution function is computed. Further optional diagnostic processing is provided.
