Answer / manoj sharma

A diesel generator is the set of diesel engine and
alternator. Disel engine is prime mover which rotates the
alternator and alternator generates the electricity.
Further diesel engine works on principle of carnot cycle,
air is compressed in a cylender, then it is compressed up
to high pressure, disel is injected to this compressed air
thus cumbustion takes place,this energy force to move the
piston in the cylendrical passage, piston is further
connected to crank shaft. on the other hand generator
wotrks on principle of electo magnetic induction, when a
DC excited rotor is rotated then at synchonous speed EMF
induced in static armature.

Answer / apurb prakash

Diesel is used as fuel for the generator.disel prodused
mechanical energy with the internal construction of
generator.then this mechanical energy is converted into
electrical energy

Answer / vijay

genrator is a machine which use diesel as fuel to run the
engine which rotate the rotor of an altenator which produse
the electricity.

Basically genrator is a machine which convert the machnical
energy into electrical energy.

Answer / sachin subhash pawar

diesel generator worked as principle of faraday's law of
electromagnetic effect.mechanical energy is converted to
electrical energy.It can stared to d.c supply i.e. 12v ,
24v.D.C supply to starter and after starting it produce
A.C. supply.Engine only use as a prime mover.

Answer / kumar

AS PER MY FIELD EXPERIENCE .IN DG SET DIESEL IS USED FOR
FUEL OF STROKE ENGINE,SO THE ENGINE PRODUCED MECHANICAL
ENERGY .THE SHAFT OF ENGINE IS COUPLING WITH GENERATOR
THEREFORE MECHANICAL ENERGY CONVERTED INTO ELECTRICAL
ENERGY .BY USING GOVERNOR WE CAN ADJUST THE SPEED OF THE
ENGINE .&WE CAN DEVELOPING OR CONTROLLING THE DG OUTPUT
VOLTAGE BY USING AVR(AUTOMATIC VOLTAGE REGULATOR).THE
CONTROLLING & DISPLAYING OF GEN SET IS OPERATING BY DC
VOLTAGE FROM BATTERY .WE CAN CHARGE THE BATTERY AT THE TIME
OF ENGINE RUNNING BY USING THE CHARGING ALTERNATOR.ITS
COUPLED WITH ENGINE SHAFT THROUGH BELT .FOR THE SAFE WE
USING STARTER MOTOR TO START ENGINE THATS MOTOR OPERATED BY
DC VOLTAGE .

Answer / p.viswanath rao

Diesel Generator is a set of engine and alternator.
(Which converts mechanical energy in to electrical energy)
here engine is using for rotating the shaft(prim mover or
crank shaft).
Rotation takes place as fallows:
1)The pistons placed in cylinders and these pistons are
connected to Crank shaft through connecting rads
2)By using diesel as a fuel the blasting takes place in
cylinders, this blasting energy can be converted in to
rotation through piston,connecting and crank shaft
3)this rotor speed strength(should be synchronous
speed)depends on firing order of the cylinders (of course on
number of poles on rotor)
4)this shaft is connected to Alternator rotor
5)this rotor contains poles, this rotor will get the D.C
supply from A.V.R through Exciter (RRA: Rotating Rectifier
assembly, it is a converter bridge)
6)So with rotor(poles) rotation the EMF will induce in main
Stator(Faraday's law of electro magnetic effect)
7)A.V.R out put depends on load effect on D.G.

Answer / aayush

A diesel generator works on the principal of Faraday's law
of electromagnetic effect. Mechanical power of the rotor is
converted into electrical power. As the rotor rotates
(because of the external voltage given to it through the
battery), EMF and hence current is generated, which is
collected by collectors connected on the stator.

Answer / gagan deep singh

Generator: IT IS A MECHANICAL DEVICE WHICH IS USED FOR
CONVERTING THE CHEMICAL ENERGY STORED IN FUEL TO THE
ELECTRICAL ENERGY. IT CONSISTS OF FOLLOWING COMPONENTS
1.DIESEL ENGINE
2.TURBINE
3.ALTERNATOR
4.COIL WITH PRIMARY $ SECONDARY WINDING OF COPPER WIRE.

1.DISEL ENGINE CONVERTS CHEMICAL ENERGY INTO MECHANICAL
WORK.
2.TURBINE CONNECTED WITH CRANSKHAFT OF ENGINE ROTATES
IN THE CORE(STATOR.
3.ALTERNETOR CONVERTS MECHANICAL ENERGY INTO ELECTRICAL
ENERGY.
4.WINDINGS ARE USED TO STEP UP OR STEP DOWN THE VOLTAGE.
