Performance Dynamometer

A Performance dynamometer is a device that measures the output of an automobile engine. It is a complex device that uses a number of measuring elements to determine the speed of an engine in its operating environment, including voltage, temperature, and current. It was invented by Dr. Arnold P. Harman in 1938 to replace the outdated mechanical equivalent of a car’s fuel gauge, currently known as the oil pressure gauge. Dr. Harman believed that the pressure gauge only showed the oil pressure at the specific moment when it was turned on, not its normal operating environment.


Performance Dynimeters is used in a variety of performance-oriented applications. They can be used for a wide range of tests, from testing the acoustics of an enclosed space to testing the durability of a heavy construction. They are also commonly used to diagnose engines or other vehicles in an auto shop. They are also frequently used by mechanics and repair personnel to determine the condition of a specific vehicle or component, such as an engine or a fan motor. Performance nanometers can also measure performance in a laboratory, making it possible to compare the performance of different parts against a standard set of standards.

The most common use for a Performance Dymat is testing the performance of a vehicle on a test track. The Dymat functions as a linear discriminator between vehicle speed classes. It can be used to pre-determine the classifications of speed, typically by evaluating a vehicle’s starting speed and acceleration. Using a dynamometer is much more accurate than traditional speed classifications using manual methods, such as E-prime or Horoscope. This makes it useful for determining the classifications of various vehicles and engines in a variety of conditions.
