When an engine has been repaired or overhauled, it may need to be tested for proper operation and power output. A piece of test equipment used to conduct such tests is the dynamometer. The following is a basic explanation of how a dynamometer works. For in-depth information about this test equipment, refer to the manufacturers manual.

The dynamometer is used to apply specific loads to an engine. It allows the technician to inspect and check the engine while it is operating. The dynamometer absorbs and measures the engines output. The basic components of a dynamometer are the frame, engine mounts, absorption unit, heat exchanger, and torque and measuring device. To properly operate a dynamometer you must complete a shop qualifications course. Dynamometers are found primarily in shore activity shops. For maintenance, refer to assigned PMS for the equipment. If your shop has no PMS maintenance for the dynamometer, follow the maintenance schedule recommended by the manufacturer.
