has anyone made there own engine dynamometer or chassis(rollerroad) dynamometer ???
What electronics and hardware are you using to capture the data when running the dynamometer ? ie torque , speed to calculate the horse power.
Great tool for tuning the IC engine also , not just power figures . What datalogging do you use analog or digital system.
1. friction engine dynamometer
2. eddy current engine dynamometer
3. water brake engine dynamometer
4. inertia engine dynamometer
5. and many other different types of engine dynamometer
One of the www.cnczone.com forum members makes some nice electronics and hardware. His website is www.sportdevices.com.
Thats a free plug for there site , as i have no connection to this site . This is one of many on the world wide web listing.
If you have a website of your own just list it this thread. Or if you have a favourite website just list it in here.
A dynamometer, "dyno" or "dyn'r" for short, is a machine used to measure torque and rotational speed (rpm) from which power produced by an engine, motor or other rotating prime mover can be calculated.
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 dynamometer. A dynamometer that can either drive or absorb is called a universal dynamometer.
In the medical realm, hand dynamometers are used for routine screening of grip strength and initial and ongoing evaluation of patients with hand trauma and dysfunction.
