The document describes a suitcase car, which is a mini car that can carry up to 80kg and fit inside a suitcase. It has a unloaded weight of up to 30kg and can be lifted and transported by one person when packed into a suitcase. The suitcase car uses a two-stroke engine but the document proposes using an electric motor and battery instead to reduce pollution and noise. The suitcase car can be assembled or disassembled in under four minutes and can carry a single person with a top speed of 30km/hr and a range of 70km on a full battery charge.

ABSTRACT:
The Suitcase car is a type of mini car designed for one person and
can carry a load up to 80 kg. Its unloaded weight is up to 30 kg. It can be
packed into a suitcase and can be lifted by any person.
For this we learned the fundamentals of Strength of Material for
calculation of load, stresses and forces acting on various parts of chassis of
our car. To select the type of drive we studied Machine Design and choose
chain drive which is best suited for the requirements. For the type of Engine
we go through Automobile Engineering and selected two stroke engines
due to its small size and good load carrying capacity.
Disassembling is the secondary issue for which we used detachable
tires and folded handle. There are so many difficulties arise in placing fuel
tank and driver seat. After all we used various ideas used small size fuel
tank and driver seat.
The innovation in this project is to produce an economically viable
and affordable car for mass so that it can carry load and can travel smoothly
on Indian roads.

INTRODUCTION:
As the population is increasing there is also increasing in demand of
the automobiles. Due to the increasing number of automobiles they will
require space for driving and also for parking. As we know there is limited
space available. Due to the increasing number of cars on roads they cause
traffic jam and also they acquired a place for parking. As the number of cars
is increasing the pollution also increases. The Portable Car (Suitcase Car) is
a foldable car which can be folded in a suitcase; hence it does not require
the parking place. The size of the Portable Car is 46”x 22” so it is five times
smaller than normal car. Due to its compactness it can be used in various
big shopping malls, industries, big campus of college etc. Portable car can
be used in shopping malls, industries and for covering short distance. It can
be used for travelling purpose on the highways.
It was originally designed & built in 1991 as part of a design
contest held at Mazda's Engineering department which was created with a
simple idea to have a 3-wheeled car inside a suitcase. Instead of waiting in
line for a taxi or shuttle, just open your suitcase & drive off.
Powered by a 59.57cc 2 stroke engine, the vehicle holds enough
fuel approximately 2 hours of driving. Can be assembled in about 15-20
seconds & comes with functional brake lights & turn signals. Vehicle was
rebuilt in a black suitcase in 1994. But as suitcase car is running on the two
stroke engine with the 27 mph that suitcase car can run for 2 hours with the
fully filled fuel tank due to the use of engine it can cause pollution and
noise.

In order to overcome above mentioned disadvantages in the present
invention we used the motor and battery instead of engine. Portable Car can
be assemble and dissemble whenever necessary and also we can carry
suitcase anywhere and if necessary we can assemble it in just less than four
minute and drive it. In this portable car we used four wheels out of that the
power is given one wheel and other wheels are supporting wheel.
If there is no use of car then we can just simply dissemble the car&
put it in to the suitcase. The portable car can carry weight up to 100kg.
Maximum speed of portable car is 30 km/hr. fully charged battery can run
up to 70km.

OBJECTIVE & SCOPE:
Transforming the car was simple:
 Open the suitcase
 Attach rear wheels
 Raise and lock steering column
 Flip up the lights
 Pull to start
Some of the major advantages of Mini cars are as follows:
 The cost of maintenance is affordable.
 The small size and light-weight make it easy to park Mini cars.
 Mini cars are so light that they can be lifted by hand for parking.
 Mini cars possessed forward entry which helped in perpendicular
parking.
Suitcase car is something different to the above concept. It is
suitable only for the clean and smooth roads. We can use this car in college
campus, school campus, office campus, at airports, on cruise etc. Beside
this, Suitcase car also have a bigger advantage that it can be folded and
packed into a suitcase. These advantages facilitate a person to carry the car
through his journey. Suitcase car is designed for a single person that can
sustain the load of an average person. It is a light- weight vehicle. All the
parts of the suitcase car are mounted inside a suitcase.

Technically
 A suitcase of large height can be used to increase the space.
 Large tire can be used.
 Weight of the suitcase can be reduced by using fiber body
suitcase.
 It can be powered by a high capacity engine having the same size.
 A CVT can be used to optimize its speed.
 Differential can be used for high speed and better control.
 Secondary systems like lighting, horn, speedometer etc. can be
attached.
 An option of self start can be installed.
According to its usage
 It can be used as a racing car.
 It can be used on cruise to travel from one point to other.
 It can be carried while traveling by train, bus, plane etc.
 It can be used in college campus, school campus, university
campus, etc.
 It can be used in a society.
 It can be used for entertainment purpose.

CONCLUSION:
Suitcase car is our main project that is presented in front of you. In
present day we are studying the chases and load analysis that is use in it. On
the first stage of my project, we are going to show to you theoretically
portion of it.
We are very glad to show to you some fraction of our live work in
this project. There are some issue that arise during live work but we have
shoot it out by discussing to each other and with fraction of effort of my
faculty members
