The Detroit Diesel Series 50 is an inline four-cylinder diesel engine, that was introduced in 1993 by Detroit Diesel. The Series 50 was developed from the existing block of its sister engine, the Series 60, which itself was initially designed by Detroit Diesel.
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
The H-engine was initially designed for use as a 6,300 hp (4,700 kW) 16 cylinder, the EMD SD90MAC; however, the early engines were found to be unreliable, and unsuccessful in the market, with the proven EMD 710 2-stroke design being preferred. The EMD four-stroke engine was resurrected in 2015 to meet EPA Tier 4 emissions regulations.
The Diesel cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected. This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine.
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 first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.
The Cleveland Diesel Engine Division of General Motors (GM) was a leading research, design and production facility of diesel engines from the 1930s to the 1960s that was based in Cleveland, Ohio. The Cleveland Diesel Engine Division designed several 2 stroke diesel engines for submarines , tugboats , destroyer escorts , Patapsco -class gasoline ...
The model 251 engine design was initiated in 1949 and, like the 244 engine, it had a bore (cylinder diameter) of 9 inches (229 mm), and a stroke of 10.5 inches (267 mm). Its designation combines Alco's identifier for that bore and stroke - 2 - with the year its design was approved for laboratory testing - 1951. Chief Engineer of Diesel Engine ...
