Customer Need / Challenge
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. The Interface Model 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 Model 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.
- Model SSMF Fatigue Rated S-Type Load Cell.
- Rod End Bearings.
- CSC Environmentally Sealed Signal Conditioner.
|HOW IT WORKS|
- The engine is loaded and secured into the dyno.
- All support systems are installed and tested.
- The engine is started.
- The dyno applies a load to engine.
- The load cell naturally reacts to the torque of the loading mechanism, utilizing the Rod End Bearings to compensate for non-linear movement.
- The load cell provides a signal through the CSC Signal Conditioner to the dyno software.
- The dyno software converts this signal to a torque reading and calculates horsepower.
