Detroit Diesel Series 92
The Detroit Diesel Series 92 is a two-stroke cycle, 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. It was a rebored (4.84025±.00125") version of its then-popular sister series (retaining the 5" piston stroke yielding 92.0 cu in), the Series 71. Both the 71 and 92 series engines were popularly used in on-highway vehicle applications.
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.
The 92 series left the market in the summer of 1995 and the Four Stroke Detroit Diesel Engine was introduced as a replacement.
In 1985, the urban bus operations in Mexico City began using this engine in two bus models known as the Masa-Somex. These were manufactured locally in Mexico.
