Abstract— In today’s era, automobile industry is growing day by
day. There is not a single place where you can’t get to see
automobiles. The Automobiles run on the tires that are filled
with the compressed air. Till so far, the system that provides
compressed air is very huge in size, consumes large amount of
electricity (AC) and are not feasible to carry with. Considering
these aspects, we can say that there is a drastic need of an air
compressor that should be energy efficient (DC), small in size
and portable to carry with. Hence here we propose a design of a
system that will provide the optimum compressed air by utilizing
minimum amount of power (DC) and will be able to run on
device such as batteries.
Keywords— AC, BDC, DC, RPM, TDC.
I. INTRODUCTION
With the advent in the field of science and technology, several
aspects have been brought forward in order to enhance the
human living exposure. Innovations in the field of science
have made our life easy and comfortable. There are several
aspects that are put forward to enhance our day to day
workability. Now, each and every field is in influence with the
technological advancements. We cannot find a single field
without technological aspects. Among all innovations,
revolution in the field of automobiles has made our life
exciting and easier.
Today automobile industry is at its peak. Huge amount of
development has been done till so far to nourish the industry
demands. Every day we see numerous vehicles running all
over. For a human, vehicles play a very important role.
Automobile vehicles constitute several parts that help to run
efficiently. Wheels are the base for a vehicle. Wheels are the
running base of the automobiles. These wheels comprises of
tires that are filled with the compressed air. Everywhere we
get to see compressed air filling points. It may be at the garage
or may be near to the petrol/diesel or gas filling stations.
Today, the way compressed air is gained is too tedious and
complex procedure. [1] Every time there is need of
compressed air for our automobiles, we need to rush to the
nearest air filling point, which is a headache for us especially
when time constraint matters. Even if we rush to the air filling
point, it is a matter of fact that we may get compressed air if
we are that much lucky because one cannot say supporting
environment will be on our side such as electricity or
availability of stored air etc. These points to a need of a well
improved option for providing compressed air at our place,

wherever we want and with minimum resources such as
electricity etc. Considering the need and unavailability of such
option, a better approach can be suggested to furnish these
requirements. A new system can be manufactured to provide
such functionalities. In such scenario, a portable air
compressor can be well functional and can fulfill situation’s
requirements.
II. EXISTING SYSTEM
Compressors are the most important tool in the industry.
Several techniques have been brought forward to design an
efficient air compressor to compress air. Till so far,
compressors are drive using steam power, turbines and
electrical energy (AC). [2]
At this instant, if you go to fill compressed air in your
automobile tires then you may find an assembly that is too
large, heavy and bulky to operate. The present air compressor
consists of several parts such as Electrical Motor (AC), Piston
Cylinder arrangement, Oil Rings and a Storage tank etc. The
major disadvantages of the existing system are that these
systems requires large amount of electricity (AC), place
dependent and complex to operate. Figure depicts how exactly
current air compressor system works.

III. MODIFIED DESIGN
The drawbacks of existing air compressor can be minimised
by changing the existing system to a certain level. Here we
propose a design of an air compressor that will definitely fulfil
the situation’s requirements.
A. Proposed System

Following figure shows a modified approach. The modified
system can be manufactured by using several components
such as DC Motor, Spur Gear, Single Cylinder Piston
Arrangement and Pressure Gauge. Here’s the block diagram
of the modified approach.
C. Spur Gear
Fig. 4 Typical Gear
Fig. 2 Portable Air Compressor
Each sub part in this system contributes a major role. Major
component of this system may include following parts.
The Spur Gear can be used in the assembly as a bridge in
between DC Motor and Piston Cylinder Arrangement.[4] It
can be used for transmitting torque from one shaft to another
shaft.
D. Single Cylinder Piston Arrangement
B. DC Motor
Fig. 3 Typical DC Motor
Dc Motor will be the fundamental part of this proposed
system. The whole assembly will work by using the energy
provided by the DC Motor. It is expected that DC Motor will
be functional at 12 volt power.[3] The main advantage of
using DC Motor is, it provides high Torque at higher RPM.

Fig. 5 Single Cylinder Piston
This part can be used to accomplish the major task of the
proposed system i.e. the task of generating the compressed air.
As this part reciprocates from Bottom Dead Centre (BDC) to
Top Dead Centre (TDC), when the piston is at BDC then the
inlet valve gets opened and it takes surrounding air. As the

piston reaches to TDC, side by side the air gets compressed
automatically.[5]
E. Pressure Gauge
At last the compressed air can be measured by using a
pressure gauge.
The proposed system will work effectively and efficiently as
far as the sub components are concerned. At first this system
will be start functional at 12 volt DC power supply from
battery of automotive. As the system gets initiated all the sub
parts will work as expected to generate the compressed air.

CONCLUSION
This way a better modified approach can be suggested to gain
compressed air by using DC Power so as to minimize the
complexity of the system and to achieve portability in terms of
compactness.
