Abstract
The apparatus for testing a device controlling the ignition of an engine comprises rotary driving means for driving the device and simulating the driving of the device in normal operation; an angular encoder mechanically coupled to the driving means for providing a series of clock pulses the frequency of which is a function of the speed of rotation of the driving means; means for producing a pulse signal representing the ignition initiating signal delivered by the device when it operates in the course of its use with the internal combustion engine; at least one circuit for measuring an angular parameter of operation of the device, the measuring circuit being connected to the encoder and to the pulse signal producing means for producing a measurement signal formed by a series of measurement pulses each of which occurs respectively in the course of a revolution of the driving means, each pulse representing the angular parameter to be measured and a display device for displaying the number of clock pulses occurring per revolution during a measurement pulse.
