These consisted of Winton prime movers and General Electric generating, control, and transmission components inside a carbody whose assembly was subcontracted to another manufacturer, since EMC did not commence regular road locomotive production until 1937.
The turbocharger was the then-new EMD mechanically assisted turbo-compressor. During engine startup, and at lower power levels, during which there is not sufficient exhaust heat energy to drive the turbine fast enough for the compressor to supply the air necessary for combustion, the engine drives the compressor through a gear train and an overrunning clutch.
The devices shown are on steam engines. Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid (steam) supplying the prime mover. As the speed of the prime mover increases, the central spindle of ...
The engine room is generally the largest physical compartment of the machinery space. It houses the vessel's prime mover, usually some variations of a heat engine (steam engine, diesel engine, gas or steam turbine). On some ships, there may be more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be ...
The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not part of the prime mover. A wired-electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power ...
The SD60 is essentially identical to the SD50 externally, but has a different prime mover, the new 16-cylinder EMD 710G3A, and a computer-controlled electrical system. Chicago & North Western 's railroad manual estimated that the SD60 is 3% more fuel efficient than one SD50, while a pair of SD60s was up to 16% more efficient than three SD40s ...
The EMD FP7 is a 1,500 horsepower (1,100 kW), B-B dual-service passenger and freight-hauling diesel locomotive produced between June 1949 and December 1953 by General Motors' Electro-Motive Division and General Motors Diesel.
The SD30C-ECO is an EMD SD40-2 re-powered with an EMD 12-710 prime mover. The locomotive is rated at 3,000 horsepower (2,200 kW) and meets EPA Tier 0 emissions regulations. [7] A similar rebuild, the SD40E3 was carried out by CSX in early 2017. [8]
