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.
In addition to the engine and generator, engine–generators generally include a fuel supply, a constant engine speed regulator (governor) in diesel and a generator voltage regulator, cooling and exhaust systems, and lubrication system. Units larger than about 1 kW rating often have a battery and electric starter motor; very large units may ...
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

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]
After overspeed has occurred, it is essential to check all machinery parts for stress. [8] The first place to start for impulse turbines is the rotor. [ 8 ] At the rotor, there are balance holes [ 9 ] that equalise the pressure difference between turbines, and if warped, would require the replacement of the entire rotor.
The world’s oldest known wild bird has sparked “special joy” among scientists after she laid an egg – her first in four years – at the age of 74. Wisdom the albatross is 74 years old.
Before mains electricity and the formation of nationwide power grids, stationary engines were widely used for small-scale electricity generation.While large power stations in cities used steam turbines or high-speed reciprocating steam engines, in rural areas petrol/gasoline, paraffin/kerosene, and fuel oil-powered internal combustion engines were cheaper to buy, install, and operate, since ...
