Engine Dynamometer
Internal combustion engines are by far the most common power source for land vehicles. From a 2-stroke motor in a lawn mower, to a V-8 stock car engine, horsepower and torque are the bench marks of engine performance.
Internal combustion engines are by far the most common power source for land vehicles. From a 2-stroke motor in a lawn mower, to a V-8 stock car engine, horsepower and torque are the bench marks of engine performance. Engine manufacturers and aftermarket suppliers use an engine dynamometer (dyno for short) to accurately measure an engines performance. An engine dyno isolates an engine’s power output to help quantify its overall performance, applying a load directly to the engine and utilizing a load cell to measure the torque absorbed by the loading mechanism. Horsepower is then calculated using the torque and RPM of the engine.
A precision S-Type Load Cell is attached to a torque arm which “feels” the torque from the engine loading system. Interface’s SSMF is a great choice because it is fatigue-rated for 1×107 fully reversed cycles, and is environmentally sealed to withstand harsh environments. Utilizing the CSC Signal Conditioner provides a clear signal to a data-acquisition system.
The load cell reacts precisely with the amount of torque being produced by the engine and provides accurate signals to the data-acquisition system. Engineers are then able to analyze the power transfer for the engine and optimize for performance.
