Test circuit for ignition coil and method for testing an ignition coil

摘要

it is a pru00fcfschaltung for testing an ignition coil (1) and a method for testing an ignition coil (1) with the pru00fcfschaltung indicated. there is a point, the previously conventional ignition coils (1) by a separate messkontakt (10) is available, but in today market ignition coils (1).a direct measurement of either spatially due to the encased implementation of the ignition coil (1) electrically by an intermediary schaltelementes (4) is available, this accessible,the circuit element (4) by a waste water with a voltage source (18) is permanently durchgeschaltet and thus between the measuring point and an accessible eingangskontakt (6) any significant potential difference disappears.instead of deactivated schaltelementes (4) of the coil (1) as a function of the schaltelementes (4) fluid control (12) connected upstream, under the water by a control signal (24) of the trigger pulse.
