This document describes the main components of a diesel engine. It includes the piston cylinder, piston, crank shaft, cam shaft, fuel controlling shaft, fuel injection pump, sump, block, turbo super charger, intake and exhaust manifolds, AC core, connecting rod, lube oil pump, and water pump. It provides details on the function and purpose of each component in powering the engine and converting reciprocating motion into rotational motion.

2.  PISTON CYLINDER
 PISTON
 CRANK SHAFT
 CAM SHAFT
 FUEL CONTROLING SHAFT
 FUEL INJECTION PUMP
 SUMP
 BLOCK
 TSC(TURBO SUPER CHARGER)
 INTAKE & EXHAUST MANIFOLD
 AC CORE
 CONNECTING ROD
 LUBE OIL PUMP
 WATER PUMP .ETC

3.  It is a hollow cylinder of high strength steel it is the most important
part of the engine, in which the piston move to and fro in order to
develop power.
 generally the cylinder has to withstand the the high pressure more
than 50 bar and temperature more than 2000*c .
 thus the material for a engine cylinder should be such that it can
retain the sufficient strength and as well as temp & pressure so in
case of heavy load engine we use cylinder of steel or aluminum
alloys.

4.  it is consider as the back bone of the engine.
 its function is to convert the reciprocating motion of the piston into
the rotary motion with the help of connecting rod in locomotive
 the crank shaft is the main shaft which starts the firing order
because in loco the crank shaft is connected to cam shaft and the
cam shaft powers FIP

5. it is considered as the heart of the engine
whose main function is to transmit the
power exerted by the burning of the charge
to the connecting rod.
 the piston is generally made up of steel
and aluminum alloy they have good heat
conductivity property and also greater
strength at high temperature

6.  cam shaft is also known as the guiding shaft .
 while manufacturing of the cam shaft we
engrave some of the guide path generally guide
the inlet and outlet valve of cylinder haed
through the push rod .
 it also guide the cross head which further guide
the FIP.
 A gear transmission is used to deliver the power
of crank shaft to the cam shaft

7.  it is the shaft which control the fuel of the FIP.
 a single fuel controlling shaft control the various FIP in a series
generally 6-8 FIP are controlled in the locomotive engines.
 these shafts are connected to the FIP with an proper fitting although
these shaft work on the spring mechanism

8. it is a simple rod which generally moves
the rocker arm which further moves the
inlet and outlet valve of the cylinder head
This push arm follows the cam shaft of
engine
It moves vertically up down.

9.  it is the the cylinder cap which is tight fit to the cylinder.
 it generally close the cylinder so that the whole process of power
generation will proceed
 note-while installation of cylinder head the piston of right 1 will be on
the top .

10. it is a linkage b/w push rod and the inlet
exhaust valve which control the valve on
the tappet of push rod

12.  it is the pump which provide the fuel to the expansion chamber it
generally takes the power from the crosshead though the cam the
whole process is that on the rotation of the FIP cam guide the cross
head section will also moves up and down which gave power to the
FIP to inject the fuel to the cylinder
 The FIP consist generally two parts:-
 1-fuel injection pump
 2 –fuel injection nozzle

13. it supplies the lube oil to FIP or to the cross
head it is a tube which pBroceed the lube
oil from the sump to the upper section of
the power pack block

14. it generally supplies the fuel from the fuel
oil tank to the FIP it is a connection pipe
b/w the fuel oil tank and the FIP section

15.  the exhaust manifold is the common duct
which receives the all the exhaust gas
from the individual cylinder head, this
exhaust manifold then finally meets the
turbo

16. the intake manifold is also a duct which
supplies the atmospheric air to the cylinder
head where the atmospheric air will fulfill
the requirement of fresh air for the purpose
of compression stroke

17.  LUBE OIL PUMP-it supplies the lube oil to the
whole power pack block it will provide lubrication
to the whole system
 WATER PUMP –it circulate the water to the
whole system to cool the system it is a type of
cooling system

18.  the sump ids generally known as reservoir of the lube oil
where It will store the maximum amount of lube oil
approx 3300ltr from here the lube oil transfer to the
whole power pack block due to the internal pressure
created into the sump and the block section.

19.  it is the upper section of the power pack where
the whole process of power generation will occur
,in to the block section the reciprocatory motion
of the piston will convert into the rotatory motion

20. it will the power the engine because while
connected to the exhaust manifold ,the
turbo takes the power from exhaust gases
from which the impeller of the TSC will
revolve and sucks the atmospheric air
which moves into the air gallery and also
to the AC core which will further cools the
power pack block

21. it is the core made up of copper material in
which the process of surface conditioning
will occurred due to the presence of
copper the temp. variation will occurs
rapidly
