DEVICE FOR MEASURING NUMBER OF TURNS OF SHAFT OF AUTOMOBILE'S ENGINE PROVIDED WITH CHROMATICITY UNIT AND COLOR-CHANGE INDICATOR Russian patent published in 2006 - IPC G01P3/48

Abstract RU 2267788 C1

FIELD: internal combustion engines exploitation.

SUBSTANCE: device has transportation vehicle network voltage variable component converter. Converter has signal-forming unit. Fragments of signal reflecting operation of ignition system have to be maximal values, i.e. peaks. Signal forming unit is made for selecting pulses mainly with duration being equal to duration of pulses of ignition system.

EFFECT: improved reliability of operation; reduced requirements to output signal/noise ration.
