Editing Dynamometer (section)

==How dynamometers are used for engine testing==
Dynamometers are useful in the development and refinement of modern engine technology. The concept is to use a dyno to measure and compare power transfer at different points on a vehicle, thus allowing the engine or drivetrain to be modified to get more efficient power transfer. For example, if an engine dyno shows that a particular engine achieves {{convert|400|N.m|lbf.ft|abbr=on|0|round=5}} of torque, and a chassis dynamo shows only {{convert|350|N.m|lbf.ft|abbr=on|0|round=5}}, one would know that the drivetrain losses are nominal. Dynamometers are typically very expensive pieces of equipment, and so are normally used only in certain fields that rely on them for a particular purpose.
