Abstract
An engine vibration imager and method of testing engine stability. An accelerometer, mounted to an engine block, is configured to detect engine vibration and generate a signal indicative of detected vibration. An amplifier, electrically coupled to the accelerometer, is configured to amplify the signal indicative of detected vibration. A light indicator, electrically coupled to the amplifier, is configured to emit light upon receiving the amplified signal. The engine vibration imager also includes an indicator disk including timing marks on a first surface of the indicator disk. The indicator disk is rotatable by the crankshaft and light emitted from the light indicator is visible at the first surface of the indicator disk and indicates on the indicator disk a point in the combustion cycle in which engine vibration is detected.
