Project about cars

1. SCIENCE – MECHANISM BEHIND
CARS.

2. THE CAR WORKS IN THE BASICS OF
FOUR MECHANISM.THEY ARE
1.Engine mechanism.
2.Steering mechanism.
3.Transmission
mechanism. 4.Breaking
mechanism.

3. It helps car to move by usageof
engine(which is “Heartof Automobiles”).
It convert chemical fuel into mechanical
energy as it results in movement of car .
In car only internal combustion engineis
used and external combustion engine is
not used here.

4. TYPES OF ENGINE
?
OTTO ENGINE(It’s normal engine
which can take fuel which are
easily flammable like Petrol , LPG
CNG.)
DIESEL ENGINE(It’s a differenttype
of engine in which first fuel will be
split into small particles to easily get
spark and then comes to engine to
burn and give energy.)

5. Steering is just a simple machine which
helps us to turn the car left or right. It’s just
a wheel shaped design located in front of
the driver’s seat.
It works by manual energy to
mechanical energy which turns the front
wheel of the car which results in turning of
car.

6. TYPES OF
STEERING:-
1. Normal Steering : Human force to
Mechanical (wheel turns) results.
2.Power Steering : It has three types like
HPS(Hydralatic Power Steering) by the help of
fluid and pressure in tube it works and
EPS(Electric Power Steering) by the helpof
electic motor it turns and thismore efficient of
steering and all luxory car is attachedby it.

7. Transmission mechanism is nothing
but gearbox. It consist of 4 to 6 gears
along Clutch. This maintains the speed of
car and front and back movement of car
and to the learners using gear is a big
task if the clear it then the could be ableto
move the car.

8. TYPES OF
GEARBOX:-
1. Normal Gearbox : This is older version
of gearbox which had 4 to 6 gear and each
makes difference in speed and takes the car. A
hand lever is given to change gears. this is
known as CVT(Continuous Variable
Transmission.)
2.Automatic Gearbox : Thisgearbox
shifts gear automatically according to the vehicle
acceleration ratio of the vehicle. We can only
change the movement direction. This is also
known as AT(AutomaticTransmission).

9. This is the important mechanism of
cars which ensure the safety of the
vehicle and also helps us to stop the
when it’s at high speed.

10. TYPES OF
BREAK:-
1. Disc Brake : It tries to stop therotor
and makes vehicle to stop.
2. Drum brake : It stop the car by the
complete frictional force of drum attached to
the
rotor.
3. Hydralic Brake : It stops thecar by
ejecting a pistol out of the rotor and make
this action by fluid in conneting by of brake
petal to the wheel.
4. Anti-Lock Brake : By this driver can
control the unwanted skids on road while we
use
