FUTURE PLANING
Soon UPSRTC may introduce 'poo bus' that runs on human
and household waste.
In March this year, the first 'poo bus' rolled out in the UK,
powered by human and householdwaste. Now, Uttar
Pradesh State Road Transport Corporationis mullingover the
introductionof these buses for intra-city services, across all
75 districts.
The corporationhas been in talks with Swedish bus maker
Scania, which produces vehicles fuelled by human waste. If
this project sees the light of day, UP will be the first state in
the country to have bio-fuel powering buses.
Top road transport officialssaid all cities across the 75
districts could have these buses. The poop of 100 humans,
they said, was all it would take to fuel a 200-km ride.
Buses that run on poop already ply the streets of Britain,
Italy, Sweden and Poland. Ravinder Singh, service manager,
Agra division of UPSRTC, said, "The Swedish bus maker
showed a presentationto our representatives on how human
excreta and householdwaste could provide a sustainable
way of fuelling public transport, while also improving urban
air quality."

ENGINE
A heat engine is a machine which converts heat energy into
mechanicalenergy. The combustion of fuel such as coal,
petrol, diesel generates heat. This heat is suppliedto
working substance at high temperature. By the expansionof
this substance in suitable machines, heat energy is converted
into useful work.

INTERNAL COMBUSTION ENGINE (I C ENGINE)
 IC engine is a type of engine in which combustion of fuel
takes place inside the engine as shown in below fig. In
these engines there is a sequence of processes.
 Compression
 Combustion
 Expansion
 Exhaust / induction.
There are two basic mechanicaldesigns to achieve these four
processes in either:
Four stroke IC engine & Two stroke IC engine

CYLINDER BLOCK
Cylinder is the main body of IC engine. Cylinderis a part in
which the intakeof fuel, compression of fuel and burning of
fuel take place. The main function of cylinder is to guide the
piston. It is in direct contact with the products of combustion
so it must be cooled. For coolingof cylinder a water jacket
(for liquidcooling used in most of cars) or fin (for air cooling
used in most of bikes) are situated at the outer side of
cylinder. At the upper end of cylinder, cylinder head and at
the bottom end crank case is bolted. The upper side of
cylinder is consists of a combustion chamber where fuel
burns. To handleall this pressure and temperature generated
by combustion of fuel, cylinder material should have high
compressive strength. So it is made by high grade cast iron. It
is made by casting and usuallycast in one piece.

19. NAME : MOHDARMAN
ROLL.NO: 1501063094 Page 19
CYLINDER HEAD
The top end of cylinder is closed by means of removable
cylinder head. There are two holes or ports at the cylinder
head, one for intake of fuel and other for exhaust. Both the
intake and exhaust ports are closed by the two valves known
as inlet and exhaust valve. The inlet valve, exhaust valve,
spark plug, injectoretc. are bolted on the cylinder head. The
main function of cylinder head is to seal the cylinder block
and not to permit entry and exit of gases on cover head valve
engine. Cylinder head is usuallymade by cast iron or
aluminium.It is made by casting or forging and usually in one
piece.

20. NAME : MOHDARMAN
ROLL.NO: 1501063094 Page 20
PISTON
A piston is fitted to each cylinder as a face to receive gas
pressure and transmit the thrust to the connecting rod. It is
the prime mover in the engine. The main function of piston is
to give tight seal to the cylinder through bore and slide freely
inside of cylinder. Piston shouldbe light and sufficient strong
to handlethe gas pressure generated by combustion of fuel.
So the piston is made by aluminiumalloyand sometimes it is
made by cast iron because light alloypiston expands more
than cast iron so they need more clearances to the bore.

21. NAME : MOHDARMAN
ROLL.NO: 1501063094 Page 21
PISTON RINGS
A piston must be a fairly loose fit in the cylinder so it can
move freely inside the cylinder. If the piston is too tight fit, it
would expand as it got hot and might stick tight in the
cylinder and if it is too loose it would leaks the vapour
pressure. To provide a good sealing fit and less friction
resistance between the piston and cylinder, pistons are
equipped with piston rings. These rings are fitted in grooves
which have been cut in the piston. They are split at one end
so they can expand or slipped over the end of piston. A small
two stroke engine has two piston rings to provide good
sealing but in a four stroke engine has an extra ring which is
known as oil ring. Piston rings are made of cast iron of fine
grain and high elastic material which is not affected by the
working heat. Sometimes it is made by alloy spring steel.

22. NAME : MOHDARMAN
ROLL.NO: 1501063094 Page 22
CONNECTING ROD
Connecting rod connects the piston to crankshaft and
transmits the motion and thrust of piston to crankshaft. It
converts the reciprocating motion of the piston into rotary
motion of crankshaft. There are two end of connecting rod
one is known as big end and other as small end. Big end is
connected to the crankshaft and the small end is connected
to the piston by use of piston pin. The connecting rods are
made of nickel, chrome, and chrome vanadiumsteels. For
small engines the material may be aluminium.

23. NAME : MOHDARMAN
ROLL.NO: 1501063094 Page 23
CRANKSHAFT
The crankshaft of an internalcombustion engine receives the
efforts or thrust supplied by piston to the connecting rod and
converts the reciprocating motion of piston into rotary
motion of crankshaft. The crankshaft mounts in bearing so it
can rotate freely. The shape and size of crankshaft depends
on the number and arrangement of cylinders. It is usually
made by steel forging, but some makers use special types of
cast-iron such as spheroidalgraphitic or nickel alloy castings
which are cheaper to produce and have good service life.

ROLL.NO: 1501063094 Page 24
ENGINE BEARING
Everywhere there is rotary action in the engine, bearings
need. Bearings are used to support the moving parts. The
crankshaft is supported by bearing. The connecting rod big
end is attached to the crank pin on the crank of the
crankshaft by a bearing. A piston pin at the rod small end is
used to attach the rod to the piston, also rides in bearings.
The main function of bearings is to reduce friction between
these moving parts. In an IC engine sliding and rolling types
of bearing used. The sliding type bearing which are sometime
called bush is use to attach the connecting rod to the piston
and crankshaft. They are split in order to permit their
assembly into the engine. The rolling and ball bearing is used
to support crankshaft so it can rotate freely. The typical
bearing half is made of steel or bronze back to which a lining
of relatively soft bearing material is applied.

CRANK CASE
The main body of the engine to which the cylinder are
attached and which containsthe crankshaft and crankshaft
bearing is calledcrankcase. It serves as the lubricatingsystem
too and sometime it is calledoil sump. All the oil for
lubricationis placed in it.

VALVES
To control the inlet and exhaust of internalcombustion
engine, valves are used. The number of valves in an engine
dependson the number of cylinders. Two valves are used for
each cylinder one for inlet of air-fuel mixture inside the
cylinder and other for exhaust of combustion gases. The
valves are fitted in the port at the cylinder head by use of
strong spring. This spring keep them closed. Both valves
usuallyopen inwards.

27. NAME : MOHDARMAN

SPARK PLUG
It is used in spark ignitionengine. The main function of a
spark plug is to conduct the high potentialfrom the ignition
system into the combustionchamber to ignite the
compressed air fuel mixture. It is fitted on cylinder head. The
spark plug consists of a metal shell havingtwo electrodes
which are insulatedfrom each other with an air gap. When
high potentialcurrent supply to spark plug it jumping from
the supply electrode and produces the necessary spark.

INJECTOR
Injector is usually used in compression ignitionengine. It
sprays the fuel into combustion chamber at the end of
compression stroke. It is fitted on cylinder head.

MANIFOLD
The main function of manifold is to supply the air fuel
mixture and collectsthe exhaust gases equallyform all
cylinder. In an internalcombustion engine two manifoldare
used, one for intake and other for exhaust. They are usually
made by aluminiumalloy.

30. NAME : MOHDARMAN
ROLL.NO: 1501063094 Page 30
CAMSHAFT
Camshaft is used in IC engine to control the opening and
closing of valves at proper timing. For proper engine output
inlet valve should open at the end of exhaust stroke and
closed at the end of intake stroke. So to regulate its timing, a
cam is use which is oval in shape and it exerts a pressure on
the valve to open and release to close. It is drive by the
timing belt which drives by crankshaft. It is placed at the top
or at the bottom of cylinder.
