How does a diesel locomotive engine work?
The ignition of diesel fuel pushes pistons connected to an electric generator. The resulting electricity powers motors connected to the wheels of the locomotive. A “diesel” internal combustion engine uses the heat generated from the compression of air during the upward cycles of the stroke to ignite the fuel.
What is locomotive mechanism?
This mechanism is an inversion four bar kinematic chain . This has four turning pairs. It is consists of frame AD which is fixed, on which two cranks AC & BD are fitted on it . Two cranks are connected to each other by means of coupling rod, which connects the other ends B and C of both cranks.
What is a locomotive structure?
A locomotive frame is the structure that forms the backbone of the railway locomotive, giving it strength and supporting the superstructure elements such as a cab, boiler or bodywork. The vast majority of locomotives have had a frame structure of some kind.
Where is Diesel Locomotive Works?
Varanasi
The Diesel Locomotive Works (DLW) in Varanasi, India, is a production unit owned by Indian Railways, that manufactures diesel-electric locomotives and its spare parts.
How traction motor works in locomotive?
Traction motors are powered by electricity and generate the power to rotate the wheels of the train. The turning force produced by traction motors is transmitted to the wheels via the driving gear unit and axle. Traction motors are typically mounted in the trucks where the wheels are housed.
How is locomotive connected?
Multiple locomotives work together using a series of cables between the locomotives that provide an electric current, keeping the trailing locomotives in sync with the leader. This is performed by a 27-pin connector, that attaches between locomotives in the consist, as well as air hoses controlling the braking system.
What voltage do diesel electric locomotives work?
Modern locomotives incorporate traction inverters, AC to DC, capable of delivering 1,200 volts (earlier traction generators, DC to DC, were capable of delivering only 600 volts).
How many gears does a diesel locomotive have?
With a speed range like this, a locomotive would need 20 or 30 gears to make it up to 110 mph (177 kph). A gearbox like this would be huge (it would have to handle 3,200 horsepower), complicated and inefficient. It would also have to provide power to four sets of wheels, which would add to the complexity.
What is DMW in railway?
DMW Patiala is a fully owned Production Unit of Indian Railways, which was setup in October 1981 as “Diesel Component Works” (DCW), to meet the ever-increasing demand of high precision maintenance spares of ALCo diesel locomotives.
How do diesel train engines work?
A diesel train works by producing incredible horsepower. In fact, whereas most cars have an engine with, perhaps, 200 horsepower, a diesel engine can produce as much as 3,200 horsepower. It converts this energy into electrical energy, producing up to 560 kilowatts of electrical power. This is converted into thrust.
How do modern locomotives work?
A locomotive is a specialized type of train car which is self-propelled, generating energy through the burning of fuel, the use of electricity, magnetic levitation, or other experimental methods. Locomotives can be used to push or pull train cars, and they can be seen on railroad tracks all over the world,…
How do locomotives operate?
Internal combustion locomotives use an internal combustion engine, connected to the driving wheels by a transmission. Typically they keep the engine running at a near-constant speed whether the locomotive is stationary or moving.
What is a diesel locomotive?
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotive have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combusition locomotives and railcars used kerosene and gasoline as their fuel.
