Dyno Testing Basics: Engine Dynos vs. Chassis Dynos …

A dynamometer or "dyno" for short, is a device for simultaneously measuring the torque and rotational speed (RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp. In addition to being used … See more An absorbing dynamometer acts as a load that is driven by the prime mover that is under test (e.g. Pelton wheel). The dynamometer must be able to operate at any speed and load to any level of torque that the test requires. See more In addition to classification as absorption, motoring, or universal, as described above, dynamometers can also be classified in other ways. A dyno that is See more Dynamometers are useful in the development and refinement of modern engine technology.
