Most forms of uninterruptible power supply (UPS) can be either powered by battery or flywheel energy. These are ready for immediate use at the instant that the mains electricity fails, but the relatively small and finite amount of stored energy they contain makes them suitable for short periods of use, typically in the order of a few dozen minutes to a couple of hours depending on the actual load.
Diesel engines in the UK can run on red diesel and rotate at 1,500 or 3,000 rpm. This produces power at 50 Hz, which is the frequency used in Europe . In regions where the frequency is 60 Hz such as in North America, generators rotate at 1,800 rpm or another divisor of 3600.
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]
The Navistar DT (Diesel Turbocharged or Diesel Turbo) engine family is a line of mid-range inline-6 diesel engines.With horsepower ratings ranging from 170 hp (130 kW) to 350 hp (260 kW), the Navistar DT engines are used primarily in medium-duty truck and bus applications such as school buses, although some versions have been developed for heavy-duty regional-haul and severe-service applications.
Dieseling or engine run-on is a condition that can occur in spark-plug-ignited, gasoline-powered internal combustion engines, whereby the engine keeps running for a short period after being turned off, drawing fuel through the carburetor, into the engine and igniting it without a spark.
Most unregulated engines will overspeed if power is applied with no or little load. [citation needed] In the event of diesel engine runaway (caused by excessive intake of combustibles), a diesel engine will overspeed if the condition is not quickly rectified. [citation needed] An example is a diesel engine powering equipment at an oil well head ...
U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator [1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit.
In the automobile industry, diesel engines in combination with electric transmissions and battery power are being developed for future vehicle drive systems. Partnership for a New Generation of Vehicles was a cooperative research program between the U.S. government and "The Big Three" automobile manufacturers ( DaimlerChrysler , Ford and ...
