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.In the 1980s and early 1990s, the Series 92 was used as a major bus engine in North America. It was also available for several other applications: Trucks, buses, motor homes, construction, fire trucks/apparatus, industrial equipment, several military vehicles, and marine applications.
