A turbocharger uses a turbine powered by exhaust gases to force more air into the engine, increasing power output. It differs from a supercharger which uses a mechanically-driven compressor. Early turbochargers were sometimes called "turbo superchargers" causing confusion. Turbochargers require lubrication of bearings supporting the rotor assembly. Variable geometry turbochargers (VGTs) like those in Tata vehicles optimize performance at all engine speeds by adjusting the geometry controlled by the ECU.

6. INTRODUCTION
An all-terrain vehicle (ATV), also known as a quad, quad bike, three-wheeler, or four-wheeler, is
defined by the American National Standards Institute (ANSI) as a vehicle that travels on low-
pressure tires, with a seat that is straddled by the operator, along with handlebars for steering
control. As the name implies, it is designed to handle a wider variety of terrain than most other
vehicles. Although it is a street-legal vehicle in some countries, it is not street legal within most
states and provinces of Australia, the United States, Canada, or the United Kingdom. In the UK,
a recent variant class of ATV is now road-legal, but there are few models available in this class.
By the current ANSI definition, ATVs are intended for use by a single operator, although some
companies have developed ATVs intended for use by the operator and one passenger. These
ATVs are referred to as tandem ATVs.
The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more
stability at slower speeds. Although equipped with three (or typically, four) wheels, six-wheel
models exist for specialized applications. Engine sizes of ATVs currently for sale in the United
States, (as of 2008 products), range from 49 to 1,000 cc (3 to 61 cu in)

7. 2 MOTIVATION
2.1 SIX WHEEL ATV
Fig.1 Six Wheel ATVs
The term "ATV" was originally coined to refer to non-straddle ridden six-wheeled amphibious
ATVs such as the Jiger produced by the Jiger Corporation, the Amphicat produced by Mobility
Unlimited Inc, and the Terra Tiger produced by the Allis-Chalmers Manufacturing Company in
the late 1960s and early 1970s. With the introduction of straddle ridden ATVs, the term AATV
was introduced to define the original amphibious ATV category.
7
8. 2.2 THREE-WHEELERS
Fig.2 Three Wheeler ATV
An early Honda US90
Honda made the first three-wheeled ATVs in 1970, which were famously portrayed in the James
Bond movie, Diamonds Are Forever and other TV shows such as Magnum, P.I. and Hart to Hart.
Dubbed the US90 and later—when Honda acquired the trademark on the term—the ATC90 (All
Terrain Cycle), it was designed purely for recreational use. Clearly influenced by earlier ATVs,
it featured large balloon tires instead of a mechanical suspension.By the early 1980s, suspension
and lower-profile tires were introduced. The 1982 Honda ATC200E Big Red was a landmark
model. It featured both suspension and racks, making it the first utility three-wheeled ATV. The
ability to go anywhere on terrain that most other vehicles could not cross soon made them
popular with US and Canadian hunters, and those just looking for a good trail ride. Soon other
manufacturers introduced their own models.
8
9. Sport models were also developed by Honda, which had a virtual monopoly in the market due to
effective patents on design and engine placement. The 1981 ATC250R was the first high-
performance three-wheeler, featuring full suspension, a 248 cc two-stroke engine, a five-speed
transmission with manual clutch, and a front disc brake. For the sporting trail rider, the 1983
ATC200X was another landmark machine. It used an easy-to-handle 192 cc four-stroke that was
ideal for new participants in the sport.
Over the next few years, all manufacturers except Suzuki, developed high performance two-
stroke machines, but did not sell as many due to the reputation already secured by Honda. These
models were the Yamaha Tri-Z YTZ250 with a 246 cc two-stroke engine and a manual five- or
six-speed gearbox and the Kawasaki Tecate KXT250 with a 249 cc two-stroke with a five-speed
gearbox. Other smaller or lesser known companies, such as Tiger ATV, Franks, and Cagiva,
produced racing three-wheelers, but in much smaller numbers. Few of these machines are known
to exist today and are highly sought by collectors. There is a fan base for three-wheelers.
Production of three-wheelers ceased in 1987 due to safety concerns three-wheelers were more
unstable than four-wheelers (although accidents are equally severe in both classes).A ban on
sales of new or used three-wheelers and a recall of all remaining three-wheelers has been
proposed by the American Academy of Pediatrics.
9
10. 2.3 FOUR-WHEELERS ATV:
Fig.3 FourWheel Atv
Suzuki was a leader in the development of four-wheeled ATVs. It sold the first model, the 1982
QuadRunner LT125, which was a recreational machine for beginners. Suzuki sold the first four-
wheeled mini ATV, the LT50, from 1984 to 1987. After the LT50, Suzuki sold the first ATV
with a CVT transmission, the LT80, from 1987 to 2006.
In 1985 Suzuki introduced to the industry the first high-performance four-wheel ATV, the
Suzuki LT250R QuadRacer. This machine was in production for the 1985-1992 model years.
During its production run it underwent three major engineering makeovers. However, the core
features were retained. These were: a sophisticated long-travel suspension, a liquid-cooled two-
stroke motor and a fully manual five-speed transmission for 1985–1986 models and a six-speed
transmission for the 87–92 models. It was a machine exclusively designed for racing by highly
skilled riders.Honda responded a year later with the FourTrax TRX250R—a machine that has
not been replicated until recently. It currently remains a trophy winner and competitor to big-
bore ATVs. Kawasaki Heavy Industries responded with its Tecate-4 250.In 1987, Yamaha Motor
Company introduced a different type of high-performance machine, the Banshee 350, which
featured a twin-cylinder liquid-cooled two-stroke motor from the RD350LC street motorcycle.
10
11. Heavier and more difficult to ride in the dirt than the 250s, the Banshee became a popular
machine with sand dune riders thanks to its unique power delivery. The Banshee remains
popular, but 2006 is the last year it was available in the U.S. (due to EPA emissions regulations);
it is still available in Canada, however.
Shortly after the introduction of the Banshee in 1987, Suzuki released the LT500R QuadRacer.
This unique quad was powered by a 500 cc liquid cooled two stroke engine with a five-speed
transmission. This ATV earned the nickname "Quadzilla" with its remarkable amount of speed
and size. While there are claims of 100+ mph stock Quadzillas, it was officially recorded by 3&4
Wheel Action magazine as reaching a top speed of over 79 mph (127 km/h) in a high speed
shootout in its 1988 June issue, making it the fastest production ATV ever produced. Suzuki
discontinued the production of the LT500R in 1990 after just four years.
At the same time, development of utility ATVs was rapidly escalating. The 1986 Honda
FourTrax TRX350 4x4 ushered in the era of four-wheel drive ATVs. Other manufacturers
quickly followed suit, and 4x4s have remained the most popular type of ATV ever since. These
machines are popular with hunters, farmers, ranchers and workers at construction sites.
Safety issues with three-wheel ATVs caused all ATV manufacturers to upgrade to four-wheel
models in the late 1980s, and three-wheel models ended production in 1987, due to consent
decrees between the major manufacturers and the Consumer Product Safety Commission—the
result of legal battles over safety issues among consumer groups, the manufacturers and CPSC.
The lighter weight of the three-wheel models made them popular with some expert riders.
Cornering is more challenging than with a four-wheeled machine because leaning into the turn is
even more important. Operators may roll over if caution isn't used. The front end of three-
wheelers obviously has a single wheel, making it lighter, and flipping backwards is a potential
hazard, especially when climbing hills. Rollovers may also occur when traveling down a steep
incline. The consent decrees expired in 1997, allowing manufacturers to, once again, make and
11
12. market three-wheel models, though there are none marketed today. Recently the CPSC has
succeeded in finally banning three-wheeled ATV's with attachments to bill HR4040. Many
believe this is in response to Chinese manufacturers trying to import three-wheeled ATV's. The
Japanese manufacturers were also behind this legislation, as they have been held responsible for
years to provide ATV Safety training and to apply special labels and safety equipment to their
ATVs while Chinese manufacturers did not.
Models continue, today, to be divided into the sport and utility markets. Sport models are
generally small, light, two-wheel drive vehicles that accelerate quickly, have a manual
transmission and run at speeds up to approximately 80 mph (130 km/h). Utility models are
generally bigger four-wheel drive vehicles with a maximum speed of up to approximately 70
mph (110 km/h). They have the ability to haul small loads on attached racks or small dump beds.
They may also tow small trailers. Due to the different weights, each has advantages on different
types of terrain.
Six-wheel models often have a small dump bed, with an extra set of wheels at the back to
increase the payload capacity. They can be either four-wheel drive (back wheels driving only), or
six-wheel drive.

13. 2.4 Racing models:
Sport models are built with performance, rather than utility, in mind. To be successful at fast
trail riding, an ATV must have light weight, high power, good suspension and a low center of
gravity. These machines can be modified for such racing disciplines as motocross, woods racing
(also known as cross country), desert racing (also known as Hare Scrambles), hill climbing, ice
racing, speedway, Tourist Trophy (TT).

14. 3.1:Center Frame supplies/startup page:
A universal front and rear equipment mount for an ATV includes a telescoping central frame
member with telescoping front and rear mounting arms extending therefrom for connection to
independent axle structures of the ATV, front and rear angled hitch brackets, each with upturned
tabs having aligned holes to receive a hitch pin, and front and rear angled pulley brackets having
pulleys mounted thereon for routing a winch cable of a winch mounted either on the front or rear
of the vehicle or on the front or rear pulley brackets. An implement can be hitched either to the
front or rear hitch bracket, and the implement can be raised or lowered by use of the winch,
which has its cable routed over selected pulleys and connected to a hitch tongue or other part of
the implement.
We started with the center frame sectionThis was a good place to start because the welding was
pretty simple - we had warping problems,and we later found out that one of the frame frame
supports was in the way of an engine mountingbolt. We ended up welding a second support on,
and then cutting out the first one. It is used to bear the whole load of the vehical. The designing
of the central frame is such that it can easily bear heavy shocks with out any breakage.

16. 3.2 Forward Frame :
The second section was the forward frame.It is used for mounting the suspension system and
arms. It took a while to make and weld all the little tabs. It is also used for fixing spindal
brackets. The holes are made with the help of a 5/8 inch drill bitt.

sitting arrangement for the biker is also made on this upper frame. The fuel tank is also fixed
with the front-lower area of this upper frame.

18. 3.4 A- Arms:
In automotive suspension, an automobile's control arm or wishbone (aka. A-arm or A-frame) is
a nearly flat and roughly triangular suspension member (or sub-frame), that pivots in two places.
The broad end of the triangle attaches at the frame and pivots on a bushing. The narrow end
attaches to the steering knuckle and pivots on a ball joint.
The upper control arm can clearly be seen at the top portion of the suspension components in the
attached photo, where it is the silver part horizontally attached to the frame inside the red body
portion and connecting to the steering knuckle near the side of the tire's wheel rim. Note the
roughly A-shaped design with the top of the A near the tire and the bottom two points connected
to the frame inside the body's space. In the photo, the A-shape is reinforced with a solid
triangular plate near the top of the A. Here's a picture of how it worked:

20. 3.5 Spindle Brackets:
Here are the spindle brackets, which attach to the end of the A-arms. It should be designed from
the material which must be capable of holding whole of the weight of the vehicle. The kingpin is
attached with this section. The material we use for making the spindle bracket is U-section of
mild steel. Figure 9 shows a spindle brackets:

21. 3.6 Suspension System:
The suspension system we used is Independent suspension. Independent suspension is a broad
term for any automobile suspension system that allows each wheel on the same axle to move
vertically (i.e. reacting to a bump in the road) independently of each other. This is contrasted
with a beam axle, live axle or deDion axle system in which the wheels are linked – movement on
one side affects the wheel on the other side. Note that ―independent‖ refers to the motion or path
of movement of the wheels/suspension. It is common for the left and right sides of the
suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties
the left and right suspension spring rates together but does not tie their motion together. Most
modern vehicles have independent front suspension (IFS). Many vehicles also have an
independent rear suspension (IRS). IRS, as the name implies, has the rear wheels independently
sprung. A fully independent suspension has an independent suspension on all wheels. Some early
independent systems used swing axles, but modern systems use Chapman or MacPherson struts,
trailing arms, multilink, or wishbones.
Independent suspension typically offers better ride quality and handling characteristics, due to
lower unsprung weight and the ability of each wheel to address the road undisturbed by activities
of the other wheel on the vehicle. Independent suspension requires additional engineering effort
and expense in development versus a beam or live axle arrangement. A very complex IRS
solution can also result in higher manufacturing costs.
The key reason for lower unsprung weight relative to a live axle design is that, for driven wheels,
the differential unit does not form part of the unsprung elements of the suspension system.
Instead it is either bolted directly to the vehicle's chassis or more commonly to a subframe.
The relative movement between the wheels and the differential is achieved through the use of
swinging driveshafts connected via universal (U) joints, analogous to the constant-velocity (CV)
joints used in front wheel drive vehicles

23. 3.7 Trunoin :
The trunion used heavy duty 1 x 2 steel. We tried to avoid warping problems by spot welding it
together first. We had trouble clamping it in place, so we used a little duct tape to help hold it
together for welding.
The bearing mounts were difficult to properly align – if we did it again, I would screw them onto
a 2x4 cut to the correct length, to hold them straight during welding.Ours also warped during
welding, we should have clamped some 1x1 to them to keep them straight. Luckily, the bearings
have a lot of forgiveness built in,and we got the whole thing lined up pretty well:

25. 5. STEERING SYSTEM:
A rack and pinion is a type of linear actuator that comprises a pair of gears which convert
rotational motion into linear motion. A circular gear called "the pinion" engages teeth on a linear
"gear" bar called "the rack"; rotational motion applied to the pinion causes the rack to move,
thereby translating the rotational motion of the pinion into the linear motion of the rack.
For example, in a rack railway, the rotation of a pinion mounted on a locomotive or a railcar
engages a rack between the rails and pulls a train along a steep slope.The rack and pinion
arrangement is commonly found in the steering mechanism of cars or other wheeled, steered
vehicles. This arrangement provides a lesser mechanical advantage than other mechanisms such
as recirculating ball, but much less backlash and greater feedback, or steering "feel". The use of a
variable rack (still using a normal pinion) was invented by Arthur Ernest Bishop, so as to
improve vehicle response and steering "feel" especially at high speeds, and that has been fitted to
many new vehicles, after he created a specialised version of a net-shape warm press forging
process to manufacture the racks to their final form, thus eliminating any subsequent need to
machine the gear teeth

26. 6.BRAKES:
6.1. Drum Brakes:
A drum brake is a brake in which the friction is caused by a set of shoes or pads that press
against a rotating drum-shaped part called a brake drum. The term "drum brake" usually means a
brake in which shoes press on the inner surface of the drum. When shoes press on the outside of
the drum, it is usually called a clasp brake. Where the drum is pinched between two shoes,
similar to a conventional disc brake, it is sometimes called a "pinch drum brake", although such
brakes are relatively rare. A related type of brake uses a flexible belt or "band" wrapping around
the outside of a drum, called a band brake.
6.2.Components Of Brake:
6.2.1.Back plate:
The back plate serves as the base on which all the components are assembled. It attaches to the
axle and forms a solid surface for the wheel cylinder, brake shoes and assorted hardware. Since
all the braking operations exert pressure on the back plate, it needs to be very strong and wear-
resistant. Levers for emergency or parking brakes, and automatic brake-shoe adjuster were also
added in recent years.
Fig.13 Back Plate
26
27. 6.2.2. Brake drum:
The brake drum is generally made of a special type of cast iron which is heat-conductive and
wear-resistant. It is positioned very close to the brake shoe without actually touching it, and
rotates with the wheel and axle. As the lining is pushed against the inner surface of the drum,
friction heat can reach as high as 600 °F (316 °C).
6.2.3. Wheel cylinder:
One wheel cylinder is used for each wheel. Two pistons operate the shoes, one at each end of the
wheel cylinder. When hydraulic pressure from the master cylinder acts upon the piston cup, the
pistons are pushed toward the shoes, forcing them against the drum. When the brakes are not
being applied, the piston is returned to its original position by the force of the brake shoe return
springs.
Fig.14 Wheel cylinder
27
28. 6.2.4.Brake shoe:
Brake shoes are typically made of two pieces of sheet steel welded together. The friction material
is either rivetted to the lining table or attached with adhesive. The crescent-shaped piece is called
the Web and contains holes and slots in different shapes for return springs, hold-down hardware,
parking brake linkage and self-adjusting components. All the application force of the wheel
cylinder is applied through the web to the lining table and brake lining. The edge of the lining
table generally has three ―V"-shaped notches or tabs on each side called nibs. The nibs rest
against the support pads of the backing plate to which the shoes are installed. Each brake
assembly has two shoes, a primary and secondary. The primary shoe is located toward the front
of the vehicle and has the lining positioned differently than the secondary shoe. Quite often the
two shoes are interchangeable, so close inspection for any variation is important.
Fig. 15 Brake Shoe
Linings must be resistant against heat and wear and have a high friction coefficient unaffected by
fluctuations in temperature and humidity. Materials which make up the brake shoe include,
friction modifiers (which can include graphite and cashew nut shells), powdered metal such as
lead, zinc, brass, aluminium and other metals that resist heat fade, binders, curing agents and
fillers such as rubber chips to reduce brake noise.
28
29. 6.2.5. Automatic self-adjuster:
The self-adjuster is used to adjust the distance between the brake shoe and the drum
automatically as brake shoes wear.

30. 7. Power Transmission System:
We use chain drive mechanism for power transmission. Chain drive is a way of transmitting
mechanical power from one place to another. It is often used to convey power to the wheels of a
vehicle, particularly bicycles and motorcycles. It is also used in a wide variety of machines
besides vehicles. Most often, the power is conveyed by a roller chain, known as the drive chain
or transmission chain, passing over a sprocket gear, with the teeth of the gear meshing with the
holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical
force into the system. Another type of drive chain is the Morse chain, invented by the Morse
Chain Company of Ithaca, New York, USA.
Sometimes the power is output by simply rotating the chain, which can be used to lift or drag
objects. In other situations, a second gear is placed and the power is recovered by attaching
shafts or hubs to this gear. Though drive chains are often simple oval loops, they can also go
around corners by placing more than two gears along the chain; gears that do not put power into
the system or transmit it out are generally known as idler-wheels. By varying the diameter of the
input and output gears with respect to each other, the gear ratio can be altered, so that, for
example, the pedals of a bicycle can spin all the way around more than once for every rotation of
the gear that drives the wheels.

31. CONCLUSION:-
The model of atv that we made from the scrap material.The independent
suspension system is used for comfort riding. The steering system used in this
atv model is rack and pinion arrangement.For the safe turning we used
ratchet system which will perform the function of the diffretial system. The
chain driveis used for transmitting the power to rare wheels.
