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 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.
The Series 92 engines were introduced in 1974. [8] Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of 4.84025 ± 0.00125 in (122.942 ± 0.032 mm) and an identical stroke of 5 in (130 mm) for a nominal displacement per cylinder of 92 cu in (1,510 cc), from which the Series 92 derives its name.

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 Detroit Diesel 149 is a series of two-stroke diesel engines manufactured by Detroit Diesel which were first announced in early 1966. After Detroit Diesel was spun off in 1988 and later acquired by MTU, production of Series 149 engines was discontinued around 2000. [9] [10]
(On the other hand I don't know how this could work because MTU engines were much larger. To my knowledge the 396 series were the smallest engines at that time (there was a 331 series for tanks only). 396 is the displacement in centilitres per cylinder (= 3.96 litres(cyl) and they had 6 to 12 cylinders and turbocharging at an early time.)--
The "V" type were built in V8, V12 and V16 configurations. In 1951, the engines received 4-valve cylinder heads, thus creating Mark II "RK" and "V" types which ran at 750-850rpm. Intercooling became an option in 1960, adding a "C" to the engine designation should it be equipped. More revisions saw the creation of the Mark III engines in 1962.
