The Potrero Generating Station was a natural gas and diesel burning electricity generating station owned by Mirant and located on a 23-acre (9.3 ha) site in Potrero Point, San Francisco, California. The plant's primary power source was a 206 MW, natural gas burning steam turbine providing baseload power and referred to as "Unit 3".
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 ...
Some parts of the generator landed as far as 80 feet away from the generator. [7] In addition to the massive and obvious mechanical damage to the diesel engine itself, evidence of overheating of the alternator was later observed (upon subsequent disassembly of the unit). [3] In this attack, the generator unit was destroyed in roughly three minutes.
A stationary engine is an engine whose framework does not move. They are used to drive immobile equipment, such as pumps, generators, mills or factory machinery, or cable cars. The term usually refers to large immobile reciprocating engines, principally stationary steam engines [1] and, to some extent, stationary internal combustion engines.
Continuous black exhaust from the stack when under a constant load is also an indication that some of the fuel is not being burned. [5] Additionally, wet stacking can result in a build up of diesel fuel in the engine which does not combust due to the low temperature in the engine. This results in a reduced fuel economy.

Generator engines are often run on natural gas (it's cheap, especially in oil or gas fields). "Diesel" engines are large, powerful and built by the sort of companies who already make diesel generators. They're also (by the fundamental Carnot cycle limit) higher compression ratio, thus potentially more efficient. So how does it work?
