A dynamometer or "dyno" for short, is a device for measuring force, moment of force (torque), or power. For example, the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (rpm). In addition to being used to determine the torque or power characteristics of a machine under test (MUT), dynamometers are employed in a number of other roles. In standard emissions testing cycles such as those defined by the US Environmental Protection Agency (US EPA), dynamometers are used to provide simulated road loading of either the engine (using an engine dynamometer) or full powertrain (using a chassis dynamometer). In fact, beyond simple power and torque measurements, dynamometers can be used as part of a testbed for a variety of engine development activities such as the calibration of engine management controllers, detailed investigations into combustion behavior and tribology.

Superflow SF-601/602 water brake chassis dynamometer and vehicle test system. The dyno is capable of measuring roll power (power applied/absorbed by the rear wheel). A chassis dynamometer measures power delivered to the surface of the "drive roller" by the drive wheels. The vehicle is often parked on the rollers, which the truck then turns and the output is measured. Testing of tandem axle rear wheel is possible with this dyno. The dyno sensors provide information on vehicle speed, fuel flow, and engine rpm. For the purpose of test, vehicle speed is generally kept at 50-60 mph with radiator fan continuously on for maximum horsepower absorption. Used for classes 7 and 8, tractors, and straight trucks.
