METHOD FOR DETERMINATION OF AUTOMOTIVE VALVE GENERATORS FAULTS Russian patent published in 2019 - IPC G01R31/34 G01M15/00 H02P9/30 

FIELD: diagnostic equipment.

SUBSTANCE: invention relates to diagnostic equipment and can be used to determine technical condition of automotive valve generators. Essence of the declared solution consists in the fact that in order to determine faults, it is proposed to record oscillograms on the power output of the automobile valve generator, having previously disconnected it from the accumulator battery and connected to the anode of the semiconductor diode, which cathode is connected to positive lead of storage battery. This eliminates the smoothing effect of the accumulator battery on the shape of the output voltage waveforms and increases information value thereof. To determine specific faults and stage of their development, it is proposed to compare the obtained oscillogram with oscillograms of characteristic faults of automobile generators given in the explanatory materials.

EFFECT: possibility of rapid determination of specific faults of automotive valve generators and stage of their development directly on the vehicle based on the shape of the obtained oscillograms.
