Are All Detroit Diesels 2-Stroke? Unveiling The Engine Truth

The Detroit Diesel Series 71 is indeed a two-stroke diesel engine series, known for its distinctive inline and V configurations. This engine series is manufactured by Detroit Diesel, a well-established company with a rich history in producing reliable and powerful diesel engines. Two-stroke engines, like the Series 71, are recognized for their unique combustion cycle, where each power stroke occurs in every two strokes of the piston. This design offers advantages such as simplicity, high power-to-weight ratio, and robustness, making the Detroit Diesel Series 71 a notable choice in various applications, including industrial, marine, and automotive sectors. However, it’s important to note that two-stroke engines often require a specific oil mixture for lubrication, which differentiates them from four-stroke engines commonly found in most vehicles today.

During the years spanning from 1970 to 1986, Detroit Diesel Allison embarked on a significant milestone by introducing its initial four-stroke engine. This marked a notable shift in the company’s engine technology. As the early 1980s approached, Detroit Diesel Allison Division underwent a structural change, resulting in the separation of diesel engine production from the broader Detroit Diesel Allison entity. Consequently, this restructuring led to the establishment of Detroit Diesel Allison Division, solely dedicated to diesel engine production. Concurrently, the production of turbine engines continued under the Allison Division name, maintaining a distinct identity within the company. This transformation in the company’s structure during the specified period highlights the evolution of its engine manufacturing capabilities and the specialization of its divisions.
