Fossil fuel reserves are in critical condition and the environment is being bombarded with all kinds of pollution. Therefore, it is easy to see why any technology that brings solutions to these problems is considered to be a bounty. Among the solutions is compressed air driven machine technology. This solution does not require any type of fossil fuel and is driven by compressed air as a fuel source. A general four stroke petrol engine (IC engine) is converted to a two stroke air compressed machine. The power output is examined by supplying compressed air from the air compressor. This method will demonstrate the concept of a green, environmentally-friendly new engine technology for future generations. The experimental results show a promising maximum efficiency percentage of 23.60 under 4.5 bar pressure under a maximum load condition. Keywords: compressed air, compressed machine, power output. INTRODUCTION As civilization grows, transport becomes an essential part of life. The world population is increasing very fast and so is the number of vehicles, in order to meet the growing transportation needs. Engines are the main component of vehicles and all types of engines use fossil fuels to run the engine (Patel, Barot, Shah, & Sharma, 2011). Fossil fuels are a non-renewable energy source, whereas on the other hand compressed air is an alternative technology produced from freely available resources in the environment (Seela, Raoa, & Raoa, 2013). The sources of non-renewable energy in this world are limited. Nowadays the use of non-renewable energy such as petrol, diesel or gas has increased rapidly. All automobiles, industries, manufacturing companies, and power plants use fossil fuel to produce energy. If these fossil fuels are used so rapidly, then it is possible their reserves will not last. So it is high time to find alternate sources of energy. A new compressed air technology provides an environmentally- friendly solution for vehicles by using air as the source of fuel. The main advantage of this is that it is clean air technology and that it is effective for reducing global warming. Researchers have already carried out many noble works in the field of compressed air technology, all aimed at providing a renewable energy source for vehicles. A piston type compressed air technology used on a motor vehicle converts the four stroke engine to a two stroke engine with valve timings of -100 to 800, -100 to 1200, and -100 to 1500. However, its travel is limited to 5 km (Wang, You, Sung, & Huang, 2014). A compressed-air driven piston engine provides a resourceful idea for the development of compressed air technology with the inlet valve opening and closing at times of the valve angle being 150°, leaving 20° for isentropic expansion. After moving of the exhaust valve, the piston moves from 150° to 170°. Finally, the closing point for the exhaust is 340°. The flow rate of air is much lower and makes the engine output lower, while the angle of valve timing is shorter (Huang, Hu, Yu, & Sung, 2013). On the other hand, the piston type compressed air engine provides valve timings of for the intake valve and exhaust opening and closing of 0° to 100°, and 180° to 300°. The lifting of the intake valve and exhaust valve is 6 mm and 8 mm during operation time of the engine. The main limitation of the system is lower valve angles and lower mass flow rate (Yu, Cai, Shi, & Fan, 2014).The conversion of a petrol engine to a compressed air engine means the engine receives air instead of petrol, and experimentally the vehicle runs about 2 km/h. The original shape of the cylinder should be changed to a two sided lobed shape. The maximum operating pressure is 4500 psi at a weight of 18.5 kg. The main disadvantages of this system is that it requires too much compressed air for running a higher mileage and the extensive cooling of piston that is needed results in a longer operating time (Arjit Mourya, 2014). The compressed air technology for a single cylinder engine has thus far reached a maximum speed of 50 km/h (Mistry Manish K., 2012). The motor development international launches a new i-pod car that is being operated by compressed air originally and this system originates a new era of compressed air technology. Prominent milestones in the research of compressed air technology have been due to Motor Development (Creutzig, Papson, Schipper, & Kammen, 2009), where a totally pollution vehicle was produced reaching a speed of 110 km/h, and with a range of 200 km. The main modification of this engine was replacement of a conventional crankshaft with a modified split crankshaft. The manufacturers tried to increase the time of the piston in an ‘out crank’ position, enabling the degree of filling in
