The [[Company:Detroit Diesel|Detroit Diesel]] '''Series 92''' is a two-stroke cycle, [[Engineering:V engine|V-block]] diesel engine, produced with versions ranging from six to 16 cylinders. Among these, the most popular were the '''6V92''' and '''8V92''', which were V6 and V8 configurations of the same engine respectively. The series was introduced in 1974 as a rebored version of its then-popular sister series, the '''[[Engineering:Detroit Diesel Series 71|Series 71]]'''. Both the Series 71 and Series 92 engines were popularly used in on-highway vehicle applications.

==History==
The Series 92 engines were introduced in 1974.<ref>{{cite magazine |url=http://www.dieselduck.info/historical/01%20diesel%20engine/detroit%20diesel/2011.04-WM-James%20Jensen%20on%20History%20of%20Detroit%20Diesel.PDF |title='Jimmy' Diesels: A Short History |author=Jensen, James |date=April 2011 |magazine=Western Mariner |access-date=16 July 2018}} [http://www.dieselduck.info/historical/01%20diesel%20engine/detroit%20diesel/index.html alternative HTML link]</ref> Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of {{convert|4.84025|±|0.00125|in|mm|abbr=on}} and an identical stroke of {{convert|5|in|mm|abbr=on}} for a nominal displacement per cylinder of {{convert|92|cuin|cc|abbr=on}}, from which the Series 92 derives its name.

While the basic mechanics of the 92 series indicated superior performance and durability, early prototypes were challenged by breakdowns resulting from the torque inherent in the design. Carl Kamradt, the senior engineer in Detroit Diesel Allison's E5, or Experimental Department, was responsible for working through the practical applications of the engine, resulting in the 92 Series becoming the favored choice for applications requiring high torque and dependability. Upon Mr. Kamradt's retirement in 1984, the E-5 division was eliminated as the 92 Series ran its course.
In the 1980s and early 1990s, the Series 92 was used as a major bus engine in [[Earth:North America|North America]]. It was also available for several other applications: [[Engineering:Truck|Truck]]s, buses, motor homes, construction, fire trucks/apparatus, industrial equipment, several military vehicles, aircraft and marine applications.

The Series 92 left the market in the summer of 1995 and the [[Engineering:Detroit Diesel 60|four stroke Detroit Diesel engine Series 60]] was introduced as a replacement.

==Features and specifications==
*9.0 litre (V6), 12.1 litre (V8), 18.1 litre (V12) and 24.1 litre (V16)
*Power ratings ranging from {{convert|253|to|950|hp|kW}}
*Supported the DDECI, DDECII, DDECIII and DDECIV.
