How does a locomotive compressor work?

Compressors in conventional locomotives are fitted with oil bath air filters while in three phase locomotives they are fitted with dry type air filters. These are connected to the suction side of the LP cylinder heads. A fan with a fan guard is provided to direct cool air on to the compressor unit in conventional loco.

What is the basic principle of diesel locomotive?

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.

How do two diesel locomotives work?

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.

Which type of compressor is used in locomotive?

Air-cooled compressors came into use in the 1940’s for diesel electric freight locomotives with a car body design that directed a free flow of air to the air compressor. In the 1950’s, enclosed car body freight locomotives were built with higher horsepower engines that required the use of water-cooled compressors.

How does a steam locomotive air compressor work?

Where does diesel locomotive work?

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 do locomotive traction motors work?

The traction motors provide propulsion power to the wheels. There is one on each axle. Each motor drives a small gear, which meshes with a larger gear on the axle shaft. This provides the gear reduction that allows the motor to drive the train at speeds of up to 110 mph.

How does a diesel locomotive 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 the thermal efficiency of a diesel locomotive?

The diesel-electric locomotive has a thermal efficiency (percent of useful work derived from a unit of fuel) of 20–25\%. Since a gallon of fuel oil contains approximately 130,000 Btu of energy, only 20–25\% of this would be available to produce work, that is, pull the train.

What type of fuel is used in locomotives?

Diesel fuel is stored in a fuel tank and delivered to the engine by an electric fuel pump. Diesel fuel has become the preferred fuel for railroad locomotive use due to its lower volatility, lower cost, and common availability. The diesel engine (A) is the main component of the diesel-electric locomotive.

How a locomotive motor can be used as a generator?

Using reversible principle of motor, the motor installed on electric locomotive and electric transmission diesel locomotive can be used as a generator. Under the effect of inertia force, driving wheel drives the drive gear, which makes the motor rotor rotate to generate power in order to produce braking torque to achieve the braking purpose.
