The ignition source of a diesel engine is the heat generated by the compression of the air in the cylinder, rather than a spark as in gasoline engines. The dieseling phenomenon occurs not just because the compression ratio is sufficient to cause auto-ignition of the fuel, but also because a hot spot inside the cylinder (spark plug electrode ...
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. [1]
Generally speaking, diesel engines have more difficulty starting at low outside temperatures than gasoline engines, and electric engines have the most problems. Diesel engines do not use spark plugs to ignite the air fuel mixture and rely only on the heat generated by compression alone to ignite the fuel.
Starting fluid is not recommended for regular use with some two-stroke engines because it does not possess lubricating qualities by itself. Lubrication for two-stroke engines is achieved using oil that is either mixed into the fuel by the user or injected automatically into the fuel supply; engines requiring premixed fuel that are run solely on starting fluid do not receive an adequate supply ...
This sudden increase in pressure and temperature causes the distinctive diesel 'knock' or 'clatter', some of which must be allowed for in the engine design. [ citation needed ] Careful design of the injector pump, fuel injector, combustion chamber, piston crown and cylinder head can reduce knocking greatly, and modern engines using electronic ...
The Series 92 engines were introduced in 1974. [8] Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of 4.84025 ± 0.00125 in (122.942 ± 0.032 mm) and an identical stroke of 5 in (130 mm) for a nominal displacement per cylinder of 92 cu in (1,510 cc), from which the Series 92 derives its name.

The Allis-Chalmers One-Ninety XT, also known as the 190XT, is a row crop tractor produced by Allis Chalmers from 1964 to 1971. The tractors are powered by diesel fuel, gasoline, or LP gas (though few of the latter two were made).
