ABSTRACT:
Methods and devices for measuring and calculating various kinds of parameters of a running engine are disclosed. A camera may be positioned to capture a plurality of images of a moving component that is being driven by the an engine. From the plurality of images, a velocity of the moving component may be measured, and an acceleration then derived. From the derived acceleration, various parameters of the running engine may be calculated, including but not limited to, number of firing cylinders, rotational rate, and relative cylinder balance. These and other parameters may then be reported, such as through a display screen, to a user. The methods and devices disclosed herein may also generate recommendations for specific kinds of maintenance to an engine based on the results of parameter measurements and calculations, then report those recommendations to a user.
