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.
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.
International offered its own V800 turbocharged diesel V8 (replacing the DVT573), with Detroit Diesel introducing the 8V92 V8 (in place of the 12V71), the Caterpillar 3406 six, and several Cummins engines, including the 1150cid KT-450 six (among the largest engines ever fitted to a roadgoing vehicle).
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.
The original M1070 is powered by a Detroit Diesel 8V-92TA 12.06-liter diesel engine with 500 hp at 2100 rpm and 1993 Nm torque at 1200 rpm. This is coupled to an Allison CLT-754 five-speed automatic transmission and Oshkosh 55000 two-speed transfer case. The M1070A1 is powered by a Caterpillar C-18 six-cylinder diesel with 700 hp.
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 ...
In 1972, the Detroit 12V71 became available as an option; though rarely ordered, the V12 engine would remain through 1978. [4] Although Detroit Diesel had developed a gas-turbine version of the GMC Astro in the early 1970s, fuel-economy concerns would keep it out of production. [ 4 ]
Brake-specific fuel consumption (BSFC) was a notable issue, which at 1.63 lb/hp·h [19] was significantly greater than that of a comparable Detroit Diesel 8V71 diesel engine (approximately 0.40 lb/hp·h), [20] even though the turbine was 1,500 lb (680 kg) lighter. Other planned improvements would target throttle lag, which was caused by ...
