The crankcase from H.M.S. is first of all cleared with water. The washing machine is rotary

type which revolve the crankcase along with it and water nozzles from all direction clear any

rust and chips. The washed cylinder is then dried in the same procedure in which instead of

water nozzles, hot air is blown. The washed and dried crankcase is than loaded on to the trolley.

The trolley is special made on bearing which can rotate the engine at any angle and engine can

be fixed at any place.

This is the most vital department of the industry as complete engines are assembled here. It

provides a clean, tidy, dust free environment under controlled temperature conditions to the

workers working on the assembly line. The assembly line is basically a belt conveyor with a

series of mounting stations built upon it to mount the crankcase or engine block and carry on

the assembly operations. The mounting is of such a type so the crankcase mounted on it can be

swiveled to convenient angular positions while working on it. The crankcase mounted at one

end of the conveyor eventually passes through each of the stages where workers keep on adding

the components one by one and finally a completely assembled engine is obtained at the end of

the assembly line. The components to be fitted are provided to the workers on the stands and

shelves behind them.

Engine is the main part of every machine. In case of tractor, a diesel engine is used because it
provides large horse power economically, because of high compression ratio. The efficiency is
further increased with the use of "TURBO CHARGERS". In Sonalika I.T.L. the engine is
assembled in various stages. These stages are discussed ahead.

STAGE 1

Crank case
The basic framework of the engine is formed by the cylinder block. It houses the liners, which
serves as bearings and guides for the piston reciprocating in them. Around the cylinders, there
are passages for circulation of coolant. Cylinder block also carried lubrication oil to various
components through drilled passages called oil galleries. Function support for the main
journals and bearing of the crankshaft. Material is used for crankcase is cast iron.

CRANKSHAFT
A crankshaft-related to Crank is a mechanical part able to perform a conversion Between
reciprocating motion and rotational-motion. In a reciprocating-engine, it translates
reciprocating motion of the piston into rotational motion. The material used for it is H.C.S
Or chromium steel.
It is typically connected to a flywheel to reduce the pulsation characteristic of the Four
Stroke Cycle, and sometimes a torsional or vibrational damper at the opposite end, to
reduce the torsional vibrations often caused along the length of the crankshaft by the
cylinders farthest from the output end acting on the torsional elasticity of the metal.

PISTON ASSEMBLY FITTING: -

The piston assembly fitted to the linear and big end is tightened to the crankshaft with 8-10
kg-m torque, the piston ring cuts should be so adjusted that there should not be in same
line.

PISTON
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors
and pneumatic cylinders, among other similar mechanisms. In an engine' its purpose is to
transfer force from expanding gas in the cylinder to the crankshaft via a connecting rod.
31
The diesel enters inside the cylinder from the ejector and the piston moves upwards and the
compression stroke take place, produces spark and the mixture of diesel and air is set on
fire and it produces an energy that pushes the piston downwards.
Pistons are made of aluminum alloy. The piston is slightly smaller than the cylinder, which
allows the piston to slide up and down. There is a clearance or gap between piston and
cylinder. The gap must be closed hence pistons rings are used, to prohibited the air fuel
mixture or oil enters to the combustion chamber.

There are two types of piston rings: -

a) Compression ring
b) Oil ring

Fig: -17 Piston connecting rod

CONNECTING ROD
In a reciprocating piston engine, the connecting rod connects the piston to the crankshaft.
Together with the crank, they form a simple mechanism that converts linear motion into
rotary motion. Connecting rod is made of forged steel.

It is attached to the top of the cylinder block, by means of studs fixed to the block. The
gaskets are used to provide a tight leak proof joint at the interface of the head and the
block. The cylinder head forms a combustion chamber above each cylinder. It also
contains valve guides, valve seats, cooling water jackets and threaded holes for spark plug
or injector. Heads are cast from cast iron or aluminum alloy.

2. Fitment of oil Pan.

INSTRUCTIONS

 Cross tightening of mounting bolts at 8.9Kg.m.

FLYWHEEL
A flywheel is a rotating mechanical device used to store rotational energy and acts as a
temporary reservoir of the energy, which stores energy when the energy supply is more
than required for an operation and releases the stored energy when the supply power does
not fulfill the needs. Flywheel is provided at the end of the crankshaft. Cast iron is used for
it.

Fig: -20 Flywheel

STAGE 10

1. Fitment of push rod, tappet and rocker arm assembly.

2. Setting of rocker into their holes.

ROCKER ARMS
A rocker arm is an oscillating lever that changes radial movement from the cam lobe into
linear movement. As the arm is acted on by a camshaft lobe, it pushes open either an intake
or exhaust valve. This allows fuel and air to be drawn into the combustion chamber during
the intake stroke or exhaust gases to be expelled during the exhaust stroke. Many modern
35
rocker arms are made from forged steel.

2. Fitment of water return line.
3. Fitment of exhaust manifold & EGR pipe.
4. Fitment of water pump and side cover.

INLET MAINFOLD

In automotive engineering, an inlet manifold or intake manifold is the part of an engine that
supplies the air to the cylinders. The word manifold comes from the old English word
manifold and refers to the multiplying of one (pipe) into many.

EXHAUST MANIFOLD

In contrast, an exhaust manifold collects the exhaust burnt gases from multiple cylinders
into a smaller number of pipes and takes those gasses outside the engine. Even distribution

36
is important to optimize the efficiency and performance of the engine.

Fig: -22 Intake Manifold Fig: -23 Exhaust Flange

STAGE 12

1. Fitment of valve cover.

2. Fitment of alternator.

ALTERNATOR

An alternator is an electrical generator that converts mechanical energy to electrical energy

in the form of alternating current. It usually mounts on the side of engine. The engine
crankshaft pulley drives the alternator through a belt at 2-3 times crankshaft speed. For
reasons of cost and simplicity, most alternators use a rotating magnetic field with a
stationary armature.
In principle, the relationship between the rotor and stator makes emf.

 STAGE 13

1. Fitment of injector.
2. Fitment of oil filter.

INSTRUCTIONS

 Setting of timing of fuel injection.

 Proper fitment of gasket and centering guide.

OIL FILTER

An oil filter is a filter designed to remove contaminants from engine oil, transmission oil,
lubricating oil, or hydraulic oil. Oil filters are used in many different types of hydraulic
machinery. A chief use of the oil filter is in internal-combustion engines in on and off road
motor vehicles, light aircraft, and various naval vessels. Other vehicle hydraulic systems,
such as those in automatic transmissions and power steering, are often equipped with an oil
filter. Gas turbine engines, such as those on jet aircraft, also require the use of oil filters.
Aside from these uses, oil production, transport, and recycling facilities also employ filters
in the manufacturing process.

Fig: -25 Oil Filters

 STAGE 14
1. Fitment of fuel filter.
2. Fitment of self-starter.

STARTER MOTOR

To start the automobile engine, the crankshaft must turn fast enough for air-fuel mixture to

enter the cylinders. An electric starter or staring motor does this job. It converts electrical

energy from the battery into mechanical energy that rotates the crankshaft. The self-starter

motor draws high cranking current from the battery to produce a high torque on the

flywheel ring so as to turn the crankshaft with the required speed. The starter motor has an

overrunning clutch that transmits torque in the direction and turns freely in other direction

When armature turns, the clutch locks and transmits cranking torque to the ring gear. As

soon as the engine starts, it spins the pinion faster than the armature. This prevents damage

to the armature from spinning at high speed.

Rework department. Engine Rework department is the sub-department of Engine Division
in ITL. Rework on engine's mainly done are for: -

1. Rejected/Faulty engines.

2. Export engines.

3. Research & Development engines.

The condition of rework on assembled engine arise when engine has defects which are
caught in Engine Testing. The assembled engine is sent to Engine Testing section where
engine is checked for proper functioning. Fault's in engine are caught when engine is run
by assembling with Dynamometer. These defects are written on pink card and engine is
sent to rework section. Here problem in engine is sorted out and engine is again sent to
testing section for testing with green card on written ready for testing (R.F.T).

6.2 Cause for Rework on Engine: -

1. High SFC :-In high specific fuel consumption, there are 3 main areas of concern with
which fuel consumption per unit of power production is high. The area of concern in
engine for high SFC are:
a) Fuel Injection Pump (FIP) problem
b) Valves seating problem
c) Injector problem

2. Leakage: - Leakage in engine is detected by supply of air and spraying diesel on engine,
then inspection is done with UV light. The spot of leakage leaves bubbles and hence
leakage spot is found. Cause of Leakage: -
a) Blow hole
b) Improper seating of valves
c) Cracks
d) Damaged Gasket
43
3. Oil pressure nil: - Lubrication oil pressure is maintained with oil pump. Oil pump
is actuated with bottom intermediate gear.
Problem of nil oil pressure can be due to:
a) Blockage in suction strainer
b) Low level of lubrication oil
c) Oil pump problem
d) Filter problem

4. Fuel Timing Problem: - For proper functioning of engine, it is necessary that injection
timing of fuel is accurate. With improper timing of fuel injection there will be problems
like less efficiency, high SFC, noisy operation, vibrations, etc.
Cause of Improper Fuel Timing are:
a) Fuel Injectors
b) Gear Train
c) FIP
d) Fuel timing incorrect

5. Water Circulation Problem: - For efficient functioning of engine it is necessary

to maintain engine at working temperature, to do this cooling of engine is done with
help of water pump.

Causes related to water circulation:

a) Low coolant level
b) Water pump problem
c) Leakage in pipeline

6. Timing Gear Noise: - Timing gear is installed in gear train which actuates other
gears. Sometimes this TIG gear makes noise

Reasons for TIG noise:

a) Improper gear fitting
b) Teeth meshing not proper
c) Low gear quality

44
6. FIP hunting: - Hunting means variation of RPM in ideal position of tractor. The
RPM should be same so that to prevent the zigzag noise from engine.
Reasons for hunting in FIP: -
a) Improper function of the rack

Purpose/AIM: -To acquire knowledge about engine

Training Chief: - This project work is assigned by ER. Malkit Singh

7.1 INTRODUCTION
Engine is simply a machine which converts heat energy into a useful mechanical

work. There are mainly two types of engine used in automobile industries:

 Internal Combustion(IC) Engine

 External Combustion(EC) Engine

An Internal Combustion Engine (IC Engine) is a type of engine that converts chemical
energy into thermal energy, to produce useful mechanical work. In an IC engine,
combustion chamber is an integral part of the working fluid circuit. The internal combustion
engines are the engines in which the combustion of a fuel occurs with an oxidizer (usually
air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an
internal combustion engine, the expansion of the high temperature and high pressure gases
produced by combustion apply direct force to some component of the engine. The force is
applied typically to pistons, turbine blades or a nozzle. The internal combustion engine is
an engine in which the burning of a fuel occurs in a confined space called a combustion
chamber. This exothermic reaction of a with an oxidizer creates gases of high temperature
and, which are permitted to expand. The defining feature of an internal combustion engine
is that useful work is performed by the expanding hot gases acting directly to cause
movement, for example by acting on pistons, rotors, or even by pressing on and moving
the entire. This contrasts with external combustion engines, such as which use the
combustion process to heat a separate working fluid, typically water or steam, which then
in turn does work, for example by pressing on a steam actuated piston.

46
Principle of operation:
Air-fuel mixture in the combustion chamber (inside the cylinder) is ignited, either by a
spark plug (in case of Spark Ignition Engines) or by compression (in case of Compression
Ignition engines). This ignition produces tremendous amount of heat and pressure inside
the cylinder. This induces reciprocating motion in the piston. Power of the piston is
transmitted to a crankshaft which undergoes rotary motion. The rotary motion is ultimately
transmitted to the wheels of the, via a transmission system, to produce propulsion in the
vehicle. As the combustion takes place internally inside the cylinder (a part of working
fluid circuit), the engine is called internal combustion engine.

Fig No. 30
7.4 VALVES

There are two types of valves

1. Inlet valve
2. Exhaust valve

Fig No. 31 Valves

1. Inlet valve: These valves are used to allow fresh air or mixture into cylinder.

49
 There is at least only one inlet valve on each cylinder head. On equal number
valve heads inlet valves are larger in diameter than exhaust valves.
2. Exhaust valve: These are used to allow burnt and unburnt gasses to escape
atmosphere. Exhaust valves are normally smaller than inlet valves in diameter.
There must be at least one exhaust valve for each cylinder.

The bigger valve is the inlet valve and the smaller one is the exhaust valve. The
spark plug lies between the two.

Difference between both is diameter.

The main reason for the size difference is to avoid pre-ignition and

knocking. The exhaust valve is the hottest part of the engine.

Different Valve assemblies

Fig no: - 32 Valve assembly parts.

Both inlet and exhaust ports are shaped to curve upwards and outwards emerging from
one or both sides of the cylinder head. It is normal to have one inlet and one exhaust
valve and porter cylinder. However, twin inlet and exhaust valve-and-port layouts are
also adopted for some high-performance or large capacity engines adopted.

50
 Fig No. 33 Valves

7.5 CHARGE STRATIFICATION

A stratified charge engine describes a certain type of internal combustion engine, usually
spark ignition (SI) engine that can be used in trucks, automobiles, portable and stationary
equipment. The term "stratified charge" refers to the working fluids and fuel vapors
entering the cylinder. Usually the fuel is injected into the cylinder or enters as a fuel rich
vapor where a spark or other means are used to initiate ignition where the fuel rich zone
interacts with the air to promote complete combustion. A stratified charge can allow for
slightly higher compression ratios without "knock," and leaner air/fuel ratio than in
conventional internal combustion engines.

51
Charge stratification diagram: -

Fig No. 34 Charge stratification

1. Homogeneous charge:
Homogeneous charge compression ignition (HCCI) is a form of internal combustion in
which well-mixed fuel and oxidizer are compressed to the point of auto-ignition. As in
other forms of combustion, this exothermic reaction releases energy that can be transformed
in an engine into work and heat.
2. Stratified charge:

i. Carburetion:

A carburetor is a device that mixes air and fuel for internal combustion engines in the

52
 proper ratio for combustion. To carburet (and thus carburetion or carburetion,
respectively) means to mix the air and fuel or to equip (an engine) with a carburetor for that
purpose.

ii. Fuel injection:

Fuel injection is having largely been supplanted in the automotive and, to a lesser extent,
aviation industries by fuel injection. They are still common on small engines for lawn
mowers, rot tillers and other equipment.

The introduction of fuel in an internal combustion engine, most commonly automotive

engines, by the means of an injector.

All diesel engines use fuel injection by design. Petrol engines can use gasoline direct
injection, where the fuel is directly delivered into the combustion chamber, or indirect
injection where the fuel is mixed with air before the intake stroke.

On petrol engines, fuel injection replaced carburetors from the 1980s onward. The primary
difference between carburetors and fuel injection is that fuel injection atomizes the fuel
through a small nozzle under high pressure, while a carburetor relies on suction created by
intake air accelerated through a Venture tube to draw the fuel into the airstream.

7.6 ENVIRONMENTAL CONCERN

The diesel engine is the most efficient prime mover commonly available today. Diesel engines
move a large portion of the world's goods, power much of the world's equipment, and generate
electricity more economically than any other device in their size range. But the diesel is one of the
largest contributors to environmental pollution problems worldwide, and will remain so, with large
increases expected in vehicle population and vehicle miles traveled (VMT) causing ever-
increasing global emissions. Diesel emissions contribute to the development of cancer;
cardiovascular and respiratory health effects; pollution of air, water, and soil; soiling; reductions
in visibility; and global climate change. Where instituted, control programs have been effective in
reducing diesel fleet emissions. Significantly reducing this sulfur content would reduce secondary
particulate matter (PM) formation and allow the use of control technologies that have proven
effective in the on-road arena. The use of essentially zero-sulfur fuels, such as natural gas, in
heavy-duty applications is also expected to continue. Technology changes, such as engine
53
modifications, exhaust gas recirculation, and catalytic after treatment, take longer to fully
implement, due to slow fleet turnover. Lastly, the turnover of trucks and especially off-road
equipment is slow; pollution control agencies need to address existing emissions with in-use
programs, such as exhaust trap retrofits and smoke inspections. Such a program is underway in
California. These and other steps that can be continued and improved will allow the use of the
diesel engine, with its superior fuel consumption, to continue to benefit society while greatly
reducing its negative environmental and health impacts. The next ten years can and must become
the "Decade of Clean Diesel."

54
 CONCLUSION

The six weeks industrial training proved to be golden opportunity for me in letting me understand
various procedures involved in machinery designing and soughing out different problem regarding
it in engine department. In this training I learnt various aspects and analysis which we carried out
in industry at the same time we learnt how to follow rules and regulations in industry. I had the
pleasure to work with one of the most reputed manufacturers in their field. I received experience
in private sector. It was a good learning time during my training. In the end, I would like to thank
all the people who helped me throughout my training to enhanced my experience.
