ABSTRACT:
An analyzer adapted to be mounted in a operable aircraft and including an oscilloscopic display of the detonation characteristics of each cylinder of an internal combustion engine. The signal input to the oscilloscope is derived from vibration sensors attached to the engine spark plugs. The synchronizing signal input to the oscilloscope is derived from pulses generated at the primary circuit of the engine magneto. Solid state electronic circuits are used throughout and switching provides the capability to separately study the characteristics of each cylinder.
