4. HISTORY OF MARUTI SUZUKI
 Maruti Udyog Limited was established in February
1981, though the actual production commenced only in
1983. It started with Maruti 800, based on the Suzuki
Alto kei car which at the time was the only modern car
available in India.
 Maruti's history begins in 1970, when a private limited
company named 'Maruti technical services private
limited' (MTSPL) was launched on November 16,
1970.
 In 1982, a license & Joint Venture Agreement (JVA)
was signed between Maruti Udyog Ltd. and Suzuki of
Japan. At first, Maruti Suzuki was mainly an importer
of cars.

November 1984, India roads witness the Iconic Omni.
 Luxury on Indian roads:- India's first luxury sedan, Maruti 1000,
launched in 1990.
 What's in a name?
 Maruti Udyog Limited is renamed Maruti Suzuki India Limited in
2007.

6. SAFETY MEASURES
Safety followed in workshop
 Never be careless while working in workshop.
 Never go without shoes in workshop.
 Always wear tight clothes while working on machine.
 Workshop floor should be free from grease and oil.
 Tools and other object should be placed at proper place.
 Never work on ant machine without proper training or guidance.
 Always use goggles or face shield, globes etc. While welding.
 Gas cylinder should be placed always from file.

7. AUTOMOBILE
A self propelled vehicle used for transportation of goods and passengers
on the ground is called an automobile. A vehicle producing power within itself
for its propulsion is known as a self-propelled vehicle.
Parts of an automobile : -
 Frame
 Suspension system
 Axles
 Wheels
 The engine or Power unit
 The power train or the transmission system
 Gear Box
 Propeller shaft
 Universal Joint
 Differential Gear
 The body or super structure

8. FRAME
Different component or units of which a motor vehicle is made
are mounted on either a frame or body. A vehicle without body is called
a chassis.
The main functions of a frame in motor vehicles are : -
 To support the vehicle's mechanical components and body.
 To deal with static and dynamic loads, without undue deflection or
distortion.
Types of frame : -
 Ladder frame
 Unibody
 Backbone tube
 X-frame
 Perimeter frame
 Platform frame

9. SUSPENSION SYSTEM
Suspension is the system of tires, tire air, springs, shock
absorbers and linkages that connects a vehicle to its wheels and allows
relative motion between the two. Suspension systems serve a dual
purpose — contributing to the vehicle's road holding/handling and
braking for good active safety and driving pleasure, and keeping vehicle
occupants comfortable.
Mathematics of the spring rate : -
 Spring rate is a ratio used to measure how resistant a spring is to being
compressed or expanded during the spring's deflection. The magnitude of
the spring force increases as deflection increases according to Hooke's
Law. F = -k x
where F is the force the spring exerts
k is the spring rate of the spring.
x is the deflection of the spring from its equilibrium position.

10. BRAKE SYSTEMS
The brakes of a car are its most important feature and, therefore, one
should give special care and attention to its maintenance. Closely
monitoring the braking system is essential to ensure safety on the road.
Luckily, the process of replacing brakes on your vehicle is both easy and
cost-effective and you can achieve expertise with a small amount of
practice.
Types of brake : -
 Disc Brakes
 Drum Brakes
 Single-Circuit Hydraulic Brakes
 Dual-Circuit Hydraulic Brakes
 Brake-by-wire:
 Antilock Braking System (ABS)
 Air Brakes
 Advanced Emergency Braking System (AEBS)

11. GEAR BOX
The gear box is necessary in the transmission system to maintain
engine speed at the most economical value under all conditions of vehicle
movement.
Types of Gear box:-
 Constant mesh gear box
with positive dog clutch.
 Constant mesh gear box
with synchromesh device.
 Sliding mesh gear box.

12. AXLE
A beam axle, rigid axle or solid axle is a dependent
suspension design, in which a set of wheels is connected laterally by a
single beam or shaft. Beam axles were once commonly used at the rear
wheels of a vehicle, but historically they have also been used as front
axles in rear-wheel-drive vehicles. In most automobiles, beam axles have
been replaced by front and rear independent suspensions.
Types of axle : -
 Drive axle
 Dead axle
 Full-floating axle
 Semi-floating axle

13. RADIATOR
Radiators are heat exchangers used to transfer thermal energy from
one medium to another for the purpose of cooling and heating. The
majority of radiators are constructed to function
in automobiles, buildings, and electronics. The radiator is always a source
of heat to its environment, although this may be for either the purpose
of heating this environment, or for cooling the fluid or coolant supplied to
it, as for engine cooling.
Types of radiator : -
 Down flow
 Cross flow

14. 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.
Types of oil filter : -
 Mechanical
 Magnetic
 Centrifugal

15. ALTERNATOR
An alternator is an electrical
generator that converts mechanical
energy to electrical energy in the
form of alternating current. For
reasons of cost and simplicity, most
alternators use a rotating magnetic
field with a stationary armature.
Occasionally, a linear alternator or a
rotating armature with a stationary
magnetic field is used. In principle,
any A electrical can be called an
alternator, but usually the term
refers to small rotating machines
driven by automotive and other
internal combustion engines.

16. CLUTCH
A clutch is a mechanical device that engages and disengages the
power transmission, especially from driving shaft to driven shaft.
Clutches are used whenever the transmission of power or motion must be
controlled either in amount or over time.
Different Kinds Of Clutches : -
 Friction Clutch
 Dog Clutch
 Cone Cutch
 Centrifugal clutch
 Hydraulic Clutch

17. STEERING
Steering is the collection of components, linkages, etc. which allow
a vessel (ship, boat) or vehicle (car, motorcycle, bicycle) to follow the
desired course. An exception is the case of rail transport by which rail
tracks combined together with railroad switches (and also known as 'points'
in British English) provide the steering function.

18. WHEEL BALANCING
The machine rotates the tyre and wheelassembly and automatically
calculates the weight and location of the balance counter weight. As a result
of wheel balancing, you should notice a smoother ride and better wear from
your tyres, again saving you time and money.
