More specifically, a dyno test evaluates the measure of torque and rotational speed, giving a reading that indicates the amount of power in the engine. A dyno test typically uses electromagnetism to measure the force or horsepower. However, a dynamometer can come in a variety of forms that all cater to slightly different applications. For example, a spring dynamometer is great for measuring a simple pulling force, but it is not so great at measuring the force of an engine or power of a machine.
For more information for the variety of dynamometers and their interesting and different applications beyond your standard vehicle, check out Explain that Stuff here. Before diving into this, we do recommend that you begin with a mild engine that can be run at peak power and that is generally quite reliable, if possible. Dyno testing allows for many vehicle owners to make the most of more insignificant findings and explore ways in which the data collected can be translated to improved power and torque in your engine.
As mentioned earlier, dyno tests are available in a variety of sizes and capabilities, so finding the right one for your vehicle and situation is important.
Instead, an experienced mechanic that specializes in European vehicles will be able to test for vehicle performance, in particular the areas of the engine that a dyno test would measure. While you can pursue dyno testing at home, the benefit of working with an expert mechanic to evaluate your vehicle performance is the tailored advice afterwards; after testing, a mechanic can determine the best ways to repair or improve your vehicle to maximize its horsepower and give you that extra punch on the road that you crave.
Gauge Pressure Sensors. Alternative Fuels. General Industrial OEM. Off-Highway Vehicles. 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.
A dynamometer can also be used to determine the torque and power required to operate a driven machine such as a pump. In that case, a motoring or driving dynamometer is used. A dynamometer that is designed to be driven is called an absorption or passive dynamometer.
A dynamometer that can either drive or absorb is called a universal or active dynamometer. 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.
In an engine dynamometer, water flow, proportional to the desired applied load, creates resistance to the engine.
Every day, we work with service depots, dealerships, and original equipment manufacturers to help them test drivetrains, engines, and transmissions in a wide range of markets around the world. When it comes to dynamometers and accessories, the number of options in the marketplace can be overwhelming. We are here to guide you through the entire process, starting with the basics.

Water Brake Water momentum transfer is used to create a load on the engine or vehicle being tested with the absorbed power heating water.
Eddy Current EC Brake An electrically controlled, air-cooled brake, the EC creates load by inducing a magnetic field in a rotating disc.
