ABSTRACT:
A transducer produces a sequence of pulses corresponding to the compressions in the chambers of an internal combustion engine. Gating signals are produced in substantial time coincidence with these compression pulses. A number of channels are coupled in parallel corresponding to the number of chambers of which compression is to be measured. The channels are successively rendered operative by the gating signals which detect the amplitude of the compression pulses, by peak detection or counting clock pulses, for example. An annunciator is coupled to the several channels to express sequentially the information stored therein.
