A dynamometer (dyno/ dyno machine) is a device used to measure the Torque and power output of an engine, motor, or other rotating machinery. It works by applying a load to the machine and measuring the torque and rotational speed produced by it. This allows for the calculation of the machine's power output, efficiency, and other performance characteristics. Dynamometers can be used in a variety of applications, including automotive testing, industrial manufacturing, and research and development.

The base of the dynamometer device (Inertia) is an electric motor. This electric motor, in connection with the roller and sensors of the device, measures rotational speed and force and automatically measures torque and ultimately the power of the device.

The most common type of dynamometer is the "absorption" or "brake" dynamometer, which uses a load-absorbing device (such as an electrical generator or hydraulic brake) to slow down the machine being tested, while measuring the amount of force or torque required to do so.
There are also other types of dynamometers, such as "transmission" or "inertia" dynamometers, which don't actually absorb power but instead measure the rate of acceleration of a known mass. These types of dynamometers are often used for testing high-performance engines and other equipment where quick and accurate measurements are necessary.

Dynamometers can be used for a variety of purposes, including:

  • Measuring the power output of engines and motors
  • Testing the efficiency of machinery and equipment
  • Monitoring the performance of industrial processes
  • Conducting research and development on new technologies and designs

Overall, dynamometers are an important tool in many industries and play a key role in helping engineers and researchers understand how machines work and how they can be improved.

💬How Many Types of Dynamometer Exist?

There are several types of dynamometers, including:

  1. Absorption Dynamometers: These measure the power output of an engine or motor by applying a load to it and measuring the resulting torque.
  2. Transmission Dynamometers: These measure the power output of an engine or motor by connecting it to a special gearbox that applies a load and measures the resulting torque.
  3. Hydraulic Dynamometers: These use hydraulic fluid to apply a load and measure the resulting torque.
  4. Electric Dynamometers: These use an electric motor to apply a load and measure the resulting torque.
  5. Eddy Current Dynamometers: These use a magnetic field to create a load and measure the resulting torque.
  6. Prony Brake Dynamometers: This use friction between a brake pad and a rotating shaft to apply a load and measure the resulting torque.
  7. Torsion Dynamometers: These use a torsion bar to measure the twisting force (torque) applied to a shaft.
  8. Piezoelectric Dynamometers: These use piezoelectric materials to convert mechanical 

stress or strain into an electrical charge, allowing for measurement of torque.

💬Dynamometer For Car and Engine Tuning:

Most dynamometers used in the automotive industry are of two types: Eddy Current Dynamometer (mentioned as the fifth case in the previous section) and Inertia Dynamometer.

  • If you need dyno tuning (dyno remap) for your car, you can do it with us, in our Tuning File Service section. We can also do this online for you. In this way, you send us the car file by visiting the approved or nearby dyno machine, and our experts, considering the car conditions, ECU, and your graphs, perform the remap for you and send you the final file.

💬What are The Best Dynamometer Brands?

There are several well-known and respected brands of dynamometers in the world, each with their own strengths and areas of expertise. The choice of the "best" brand will depend on the specific needs and requirements of the user.

Some of the top dynamometer brands include:

  • Dynojet: A company that specializes in producing dynamometers for high-performance motorcycles and automotive vehicles.
  • SuperFlow Technologies Group: Known for their expertise in making engine and chassis dynamometers for industrial, performance, and research applications.
  • Mustang Dynamometer: A company that produces a wide range of dynamometers for different types of engines and equipment, including electric motors and diesel engines.
  • MAHA USA: A leading manufacturer of chassis dynamometers and testing equipment for automotive and industrial applications.
  • AVL: A global company that provides test systems and solutions for automotive and aerospace industries, specializing in powertrain and emissions testing.
  • Power Test Inc. - a US-based manufacturer of dynamometers and testing equipment for a variety of applications, including engines, transmissions, and hydraulic systems.

These are just a few examples of some of the top dynamometer brands in the world. It's important to carefully evaluate your specific needs and requirements before choosing a dynamometer, and to work with a reputable supplier or vendor who can help you find the right solution for your business or research needs.

🏁Pros of Dyno Tuning:

Dyno tuning can have several potential benefits for a vehicle, including improved performance and fuel efficiency. A properly tuned engine can also result in reduced wear and tear on the vehicle's components, which could help to extend the lifespan of the engine. Additionally, dyno tuning may allow a vehicle owner to make modifications or upgrades to their vehicle, such as installing aftermarket parts or increasing the boost pressure on a turbocharged engine, which can lead to increased horsepower and torque.
