5. INTRODUCTION
The concept in the report is strictly based on HONDA
manual cars. The report describes about components and
features of parts of cars or vehicle . It covers the light four-wheeler
vehicle. The description is about as follow:-
• Tools and equipment used in workshop.
• Suspension system of cars.
• Steering system of cars.
• Battery and battery recharge.
• Brakes .
• Some other components.

8. SUSPENSION SYSTEM
It is the term given to the system of spring. Shock observe and
the linkage that connects a vehicle to its wheel. Suspension
system serve a dual purpose-contribution to the car’s road
handling /holding and braking for good active safety and
driving , pleasure , and keeping vehicle occupants
comfortable and reasonably well isolated from road noise ,
bumps and vibrations etc. these goals are generally at odds ,
so the tuning of suspension involves finding the right
compromise. It is important for the suspension to keep the
road wheel in contact with the road surface as much as
possible, because all the forces acting on the vehicle do so
through the contact patches of the tyre. The suspension also
protects the vehicle itself and any cargo or luggage from
damage and wear. The design of front and rear suspension
of a car may be different.

10. STREEING SYSTEM
 Basically steering system is of three types. These are as follow:-
 Mechanical Steering system.

 Hydraulic Steering system.

 Electrical Steering system.
 In average conditions hydraulic steering is used. When driver rotates the
steering wheel it applies forces on drive shaft. Drive shaft consists of steering
boots and end. Steering boot is made up of rubber, this rubber by contraction
makes drive shaft to take turn even when vehicle is moving in speed.

 The combination of steering system and transmission system are so connected
to the tyres that steering system even works when vehicle is at high speed
without effecting its speed. The soul job of steering system is to take turn on
road.

12. TRANSMISSION SYSTEM
 Transmission system acts like arteries and veins of a vehicle or it is spine of the
vehicle. Transmission system transmits engine power to tyres.
 The main components of transmission system are given as follow. The
component of transmission system are given as follow . The components are so
arranged and assembled in a system that they make the equivalent effect as per
wish of the driver.
 Clutch
 Gears
 Differential
 Sun and Star pinion
 Tyres

14. CLUTCH
 It disconnects and connects the engine power to
differential or gear box in manual cars. Where clutch is
in use or is pressed by driver’s feet the it tends to
restrict the engine power to reach gear box. Now in
advanced or high performance cars torque converter is
used instead of clutch because it is more accurate, safe
and efficient then clutch. Clutch plates and pressure
plate are connected to each other with direct contact.

16. GEAR
 Gear box is assembly of circular types of concentric plates
that has teeth on there curved surface. The main task of
gear is to change the torque and R.P.M (Revolutions Per
minute) of tyre. Whenever gear of vehicle is changed, the
speed and torque of car is also changed. Smaller the
designated number of gear more will be torque and lesser
will be the R.P.M or vice – versa.

 Commonly vehicles have 4 to 5 gears. Whenever gear is
adjusted to neutral then power coming from the engine is
not transmitted to tyres, hence at that time, gear produces
zero power and zero R.P.M.

17. DIFFERENTIAL
 A large circular gear that is used to transmit final power
 coming from engine tyres.
 Differential is used to transmit equal amount of torque to
both tyres at 90 degree
 Whenever vehicle takes a turn, the inner wheel are
provided less moment and outer tyre are provided more
moment for easy turn.

18. BATTERY AND BATTERY
RECHARGING
 Battery is device that supplies current to vehicle components
which are used in many ways. Battery is used to run wipers,
headlights starter and many other components. Battery after
being used for a long time loos the concentration of charge,
hence it produce less current then its claimed current value. So
in order to recharge battery the following 2 systems are
introduced in vehicles.
 Ø DYNAMO:- Dynamo is device that produce A.C current. It
converts mechanical energy into electrical energy of A.C type.
When flux changes in the dynamo, it produces current. Dynamo
was used to recharge the battery of vehicle. Battery in all vehicles
have same voltage but they come in different ampere value. But
dynamo because of having some limitation is not now used in
new advanced vehicle with compatible assemblies. So to
overcome this ALTERNATOR is designed.

20. BRAKING SYSTEM
 BRAKES:- Brakes are devices that are directly introduced to vehicle’s tyre. The
brakes are used to lower down the acceleration of vehicle or to stop the vehicle.
 Most commonly brakes are divided into 2 types:-
 Disc brakes or quick brakes.
 Drum brakes.
 Disc brakes or quick brakes:- In disc brake a circular disc connected to tyre
rotates in between 2 lather. Disc brake works on hydraulic principle. There are
pistons introduced to lather of disc brakes whenever the driver presses the
brake by feet the piston expand and hold the disc tightly. As this disc is very
tightly connected to tyre so when this disc stops to rotate, it stops the tyre too.
Disc brake is also called quick brake because it stops vehicle very quickly.
Basically disc brake is used in light vehicle because light vehicle produce less
momentum and are safe to stop quickly.

22. CRANK SHAFT AND ITS
COMPONENT
 MAJOR PARTS:-
 Fly wheel side.
 Timing side.
 General (commonly there are five general).
 Weights.
 CONCEPT OF CRANK SHAFT:-
 When the key of vehicle is on then it starts the vehicle. Starter rotates the fly
wheel and hence starts the engine. Piston in engine rotates the crank shaft.
When piston takes the power stroke then crank shaft gets power to rotate but
rotation to crank shaft is provided by fly wheel by other three strokes i.e.
suction compression and exhaust. Hence the main stroke is power stroke.

24. MAIN PARTS OF ENGINE
 Head (aluminium alloy)
 Block (cast iron)
 Valve (inlet and exhaust)
