USS Silversides (SS-236). Fairbanks Morse & Co. 38 8-1/8 diesel engine. Historically, the opposed-piston engine was used in U.S. diesel-electric submarines of World War II and the 1950s. [5] Surviving diesel-electric submarines with these engines include USS Pampanito, USS Blueback, USS Ling, and USS Torsk.
Disadvantages of a diesel electric transmission are the potential complexity, cost, and decreased efficiency due to energy conversion. [dubious – discuss] Diesel engines and electric motors are both known for having high torque at low rpm, this may leave high rpm with little torque. Typically a petrol engine is paired with electric motors for ...
The EMC EA/EB is an early passenger train-hauling diesel locomotive built from May 16, 1937, to 1938 by Electro-Motive Corporation of La Grange, Illinois for the Baltimore and Ohio Railroad. [ 1 ] [ page needed ] They were the first model in a long line of passenger diesels of similar design known as EMD E-units .
Boston Neoplan DMA-460LF dual-mode trolleybus, operating in diesel mode (with its trolley poles lowered). A dual-mode bus is a bus that can run independently on power from two different sources, typically electricity from overhead lines like a trolleybus or from batteries like a hybrid bus, alternated with conventional fossil fuel (generally diesel fuel).
Miniature two-stroke "diesel engine". Note the T-bar on top for adjusting the compression. A carbureted compression ignition model engine, popularly known as a model diesel engine, is a simple compression ignition engine made for model propulsion, usually model aircraft but also model boats.
All models have chassis and running gear, generator, traction motors and controls from GE, and Ingersoll Rand provided its 10 × 12 diesel engine. [6] The principle of operation was the same as modern locomotives, [7] the diesel engine driving a main generator of 600 volts DC with four axle-hung traction motors. [8]
Power was provided by twin 900 hp (670 kW) 12 cylinder Winton 201-A diesel engines in each power unit, exceeding by 50% the most power that could be attained with a single engine at that time. The added "headroom" in power extended the life of mechanical parts, which was a critical issue with early diesel engines in locomotives.
Powered by twin General Motors Detroit Diesel 6-71 diesel engines, which produce a combined 300 horsepower (224 kW), its drivetrain is unusual because the two diesel engines are used to drive the electric DC generator from both sides, one with clockwise rotation and the other with counter-clockwise rotation.
