Diesel rotary uninterruptible power supply devices (DRUPS) combine the functionality of a battery-powered or flywheel-powered UPS and a diesel generator. When mains electricity supply is within specification, an electrical generator with a mass functions as motor to store kinetic energy in an electro-mechanical flywheel .
A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...
Because the flywheels are a mechanical power source, it is not necessary to use an electric motor or generator as an intermediary between it and a diesel engine designed to provide emergency power. By using a transmission gearbox, the rotational inertia of the flywheel can be used to directly start up a diesel engine, [ 11 ] and once running ...

Where a diesel-electric locomotive is equipped for dynamic braking, the braking resistor may be used as a load bank for testing the engine-generator set. On electric railways , old electric locomotives no longer required for regular service sometimes get converted into mobile load banks for testing the overhead line equipment and power ...
For 62 years, Waukesha was an independent supplier of gasoline engines, diesel engines, multifuel engines (gasoline/kerosene/ethanol), and LNG/propane engines to many truck, tractor, heavy equipment, automobile, boat, ship, and engine-generator manufacturers. In 1906, the Waukesha Motor Company was founded in Waukesha, Wisconsin.
