ANALYTICAL SIMULATION, FABRICATION AND DESIGN OF COMPRESSED AIR DRIVEN ENGINE FROM FOUR STROKE PETROL ENGINE

Abstract

As the modern world is pressed hard with the fuel and energy crises, compounded by all kinds of pollution, any technologies which bring out relief to this problem will be considered as a healing on the wound. One of such technologies, is basically the development of somewhat new engine which runs on compressed air and doesn’t require any of well known fuels like petrol, diesel, CNG, Bio-diesel, LPG, hydrogen etc. This technology replaces most types of fuels known today and also solves the pollution related issues to a large extent as the exhaust is non- polluting and at a lower temperature than atmosphere when measured practically up to 5ºC. Since the engine runs on high pressurized air, exhaust undoubtedly being only air, making it very close to zero pollution engine. Heat generation is not there because no combustion is present there, hence the engine doesn’t require any cooling system due to which cost is reduced. Also the weight, volume and vibration are reduced. An Compressed Air Driven Engine uses the Compressed Air Technology(CAT) for its working. CAT now a days is widely preferred in different industries for research and development in developing different types of drives for various purposes. CAT is not very much complex. It is based on principle that if we compress the air in a cylinder then the air will be holding some energy within it due to compression. Now this energy will be used in the desired purpose. When the compressed air inside the cylinder expands, the energy is being utilized to do the desired work. Early cost analysis have indicated that the engine is very much cost effective when compared with the petrol and diesel engines and the operational cost is approximately ten times lower. Though the value of efficiencies are lower as the losses were high. However this concept could be applied in a professionally designed engine or in already existing engines to improve the performance.
