. 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. Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of and an identical stroke of for a nominal displacement per cylinder of , 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

Model number
The model number indicates the basic configuration of the engine. The model designator consists of the number of cylinders (6, 8, 12, or 16), the block layout (V), engine series (92), and a lettered suffix which provides information about forced induction (T for turbocharged, A for aftercooled), so for instance, an 8V92TA designates a Series 92 V8 engine that is turbocharged and aftercooled.
