The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938.. This engine was in high demand during WWII, necessitating a dramatic increase in output: about 57,000 6-71s were used on American landing craft, including 19,000 on LCVPs, about 8,000 on LCM Mk 3, and about 9,000 in quads on LCIs; and 39,000 ...
The GM Diesel/Detroit Diesel model 6051 Quad power pack consists of four inline 2-stroke diesel 6-71 engines mounted to one gearbox, usually with one shaft coming out of the power unit. The power units were fitted on landing craft and ships during World War II , ships including LCI(L) , [ 1 ] Prab (741) and Nahka (751) were fitted with two of ...
The engine's compression ratio is 18.7:1 with a 4.250 inch bore and a 5.00 inch stroke. [1] The engine weighs 2,185 lb (991 kg) and is 54 inches long, 29 inches wide and 41 inches tall. [1] At 2,100 revolutions per minute the engine is capable of producing 230 horse power (172 kilowatts). [1] V-type versions of the 71 series were developed in 1957.
In 1962 GM's Electro-Motive Division (EMD), which had its own marketing and service infrastructure from its years in the locomotive business, took over the production and marketing of large diesel engines formerly produced by the Cleveland Diesel Engine Division. [2] In 1965 GMDD was absorbed by the General Motors Detroit Diesel Engine Division ...

The same basic considerations are employed (the GM/EMD 567 and the GM/Detroit Diesel 6-71 engines were designed and developed at the same time, and by the same team of engineers and engineering managers). Whereas all EMD and Detroit Diesel two-stroke engines employ forced induction, only some EMD engines employ a turbo-compressor system.
The engines were also sold for marine and stationary applications. In a 1938 reorganization, Winton Engine Corporation became the GM Cleveland Diesel Engine Division, and GM's Detroit Diesel Engine Division began production of smaller (50–149 cu in (0.8–2.4 L) per cylinder) diesel engines. Locomotive engines were moved under the GM Electro ...
The ancestor of Detroit Diesel was the Winton Engine Company, founded by Alexander Winton in 1912; Winton Engine began producing diesel engines in fall 1913. After Charles F. Kettering purchased two Winton diesels for his yacht, General Motors acquired the company in 1930 along with Electro Motive Company, Winton's primary client.
