• Now-a-days, automobiles consume a large number of fossil fuels. However, the
consumption of fossil fuels has brought many serious environmental problems
• A compressed air engine is a type of motor which does mechanical work by
expanding compressed air.
• A Compressed-air engine is a pneumatic actuator that creates useful work by
expanding compressed air.
• A compressed-air vehicle is powered by an air engine, using compressed air, which
is stored in a tank.
• Instead of mixing fuel with air and burning it in the engine to drive pistons with hot
expanding gases, compressed air vehicles use the expansion of compressed air to
drive their pistons.

2) NEED/NECESSITY/MOTIVATION FOR SELECTION OF PROJECT
 Compressed air engines (CAEs) are a type of engine that use compressed air to drive pistons , thereby generating
mechanical work.
 The need for and interest in compressed air engines stem from several factors:
• Environmental Concerns: CAEs produce no direct emissions during operation, making them an attractive option for
reducing pollution and greenhouse gases, especially in urban areas .
• Renewable Energy Integration: Compressed air can be stored and used in conjunction with renewable energy sources, such
as wind or solar power, to create a more sustainable energy system.
• Operational Benefits: Simplicity and Safety: CAEs are mechanically simpler and safer than internal combustion engines, as
they do not involve combustion or high temperatures.
• Lower Maintenance: With fewer moving parts and no need for fuel combustion, CAEs generally require less maintenance
and have a longer operational life.

 Economic Factors :
• Cost-Effectiveness: Depending on the source of the compressed air and the scale of deployment, CAEs can be a
cost-effective solution, particularly in applications where conventional energy storage or generation systems are
not viable.
• Decentralized Power: CAEs can be used in off-grid or remote areas, providing a decentralized power source
without relying on extensive infrastructure .
 Applications:
• Transport: There is potential for CAEs in various transport sectors, including urban vehicles, where zero-emission
and noise reduction are critical.
• Industry: CAEs are used in industrial applications where compressed air is already a common utility, such as in
pneumatic tools and machinery.
 Overall, compressed air engines offer a promising alternative to traditional internal combustion engines and
batteries, especially in contexts where environmental impact, safety, and operational simplicity are paramount.

3) OBJECTIVES OF PROJECT WORK
 Environmental Sustainability:
• Zero Emissions: Develop engines that produce no direct emissions during operation to reduce air pollution and greenhouse gas
emissions.
• Reduce Fossil Fuel Dependence: Minimize reliance on fossil fuels by providing an alternative energy source that can be

• Cost-Effectiveness: Reduce Operational Costs: Lower the operational and maintenance costs compared to traditional internal
combustion engines due to simpler mechanical designs and fewer moving parts.
• Affordable Energy Solutions: Offer a cost-effective energy solution, particularly for applications in remote or off-grid areas where
conventional energy infrastructure is lacking.
• Enhance Reliability: Design engines with long operational lifespans and reduced maintenance needs to ensure reliable
performance over time.

SELECTION OF COMPONENTS
Pneumatic Actuator:
• A pneumatic actuator converts energy in the form of compressed air
into motion.
• A pneumatic actuator can move something
in a linear motion or a rotary motion.
• Linear pneumatic actuators include
the spring/diaphragm style and the piston style.

10. 10
 Wheel :
• The motor converts air power to mechanical power, which is transferred to the wheels and
is used to operate the vehicle.
• In this way, compressed air acts not as an energy source like gasoline but as an energy
storage medium similar to an electric battery.
 Pneumatic Pipes :
• Pneumatic Pipes can handle high operating pressure because the FRP also stops oxygen
and other gases from entering the pipe.
• For the provision of compressed air, gas, and oxygen, K.P.T. Pneumatic pipes are a
trustworthy and safe option.
 Single Solenoid Valve :
• Solenoid valves are often used to manage the intake control or the inlet valve in screw compressors.
• Available as either de-energised opening or de-energised closing version
• These types of valves deliver higher energy efficiency, gentle start-up and a lower pressure
fluctuation range.

11. 11
 Bearing :
• Bearings have a very important job – enabling the rotation of your wheels.
• They make sure your wheels run smoothly with minimal friction.
• They also maintain correct wheel tracking and can even play a role in providing your vehicle's
drive systems with wheel speed sensor signals.
 Rack :
• The compressed air is under high pressure thus it exerts a force on piston due to which the
piston moves.
• This linear movement of piston is converted into rotary motion by help of rack and pinion
(sprocket) like arrangement.
 Connecting Rod :
• The connecting rod is required to transmit the compressive and tensile forces from the piston.
• In its most common form, in an internal combustion engine
• It allows pivoting on the piston end and rotation on the shaft end.

12. 12
WORKING
BASIC PRINCIPLE :
• On compression, the work done by the pump gets stored as pressure energy. This compressed air is then stored in
cylinders/tanks for later use.
• When this air is allowed to expand, the pressure energy of air gets converted to kinetic energy and causes propulsion. The
same principle is used for engines.
• Air compressors work by forcing atmospheric air under pressure to create potential energy that can be stored in a tank for
later use.
• Just like an open balloon, the pressure builds up when the compressed air is deliberately released, converting the potential
energy into usable kinetic energy.
• A pneumatic motor (air motor), or compressed-air engine, is a type of motor which does mechanical work by expanding
compressed air.
• Pneumatic motors generally convert the compressed-air energy to mechanical work through either linear or rotary motion.

APPLICATIONS
1. In industrial applications, it is used in two ways: as energy and as part of a process. These are
referred to as Energy Air and Active Air respectively. First of all, Energy Air is used for storing
and transmitting energy in order to do mechanical work.
2. Applications of compressed air include: Aerospace, Automotive, Chemical Manufacturing,
Electronics, Food and Beverage, General Manufacturing, Glass Manufacturing,
Hospitals/Medical, Mining, Pharmaceuticals, Plastics, Power Generation, Wood Products and
many more.
3. In the industrial manufacturing process, air compressors are used to provide high-pressure gas
to drive machinery and equipment, such as pneumatic motors, pneumatic pistons, pneumatic
valves, etc. They can also be used to operate pneumatic valves in hydraulic systems.
4. Air compressors are devices powered by either an electric motor or a diesel engine. Their role
is to deliver compressed air. The compressed air is then used to power a wide range of tools,
equipment, and machines across various industries.
5. Energy Air is used for storing and transmitting energy in order to do mechanical work. More
specifically, air compressors power pneumatic production equipment, operate lathe chucks,
pressure-clean parts, and convey or cool components during production.
