The Detroit Diesel Series 53 is a two-stroke diesel engine series, available in both inline and V configurations, manufactured by Detroit Diesel as a more compact alternative to the older Series 71 for medium and heavy duty trucks. The number 53 refers to the nominal swept displacement per cylinder in cubic inches.
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.
6.2L fitted to a 1987 HMMWV. The original 6.2 L (379 cu in) diesel V8 was introduced in 1982 for the Chevrolet C/K and was produced until 1993. The 6.2L diesel emerged as a high-fuel-economy alternative to the V8 gasoline engine lineup, and achieved better mileage than Chevrolet's 4.3L V6 gasoline engine of the 1980s, at a time when the market was focused on power rather than efficiency.
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 Detroit Diesel Series 110 is a two-stroke diesel engine series, available in straight-6 cylinder configuration (in keeping with the standard Detroit Diesel practice at the time, engines were referred to using a concatenation of the number of cylinders and the displacement, so this was a model 6-110).
These engines were used by IHC for some heavy-duty applications until 1935, although their own large engines (525 cu in (8.6 L) FBD and 648 cu in (10.6 L) FEB) had appeared in 1932. [6] The medium-duty 1930 A-series trucks received the all-new 278.7 cu in (4.6 L) FB-3 six-cylinder engine, with overhead valves and seven main bearings.
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 firing order of the engine is 1-5-3-6-2-4. [1] 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]
