TECHNICAL REVIEW ON STUDY OF COMPRESSED AIR VEHICLE (CAV)

摘要

Diesel and Petrol engine are frequently used by automobiles industries. Their impact on environment is disastrous and can't be neglected now. In view of above, the need of some alternative fuel has been arises which lead to the development of CAVs (Compressed Air Vehicle). It is an innovative concept of using a pressurized atmospheric air up to a desired pressure to run the engine of vehicles. Manufacturing of such vehicles would be environment friendly as well as put the favorable conditions for the cost. Applications of such compressed air driven engine are in small motor cars, bikes and can be used in the vehicles to be driven for shorter distances. This technology states that, if at 20 degree C, 300 liters tank filled with air at 300 bar carries 51MJ of energy, experimentally proved. Under ideal reversible isothermal conditions, this energy could be entirely converted to mechanical work which helps the piston and finally crankshaft to rotate at desired RPM (revolutions per minute). The result shows the comparison of different properties related to CAV and FE (Fuel Engines). For example emission of toxic gases, running cost, engine efficiency, maintenance, weight aspects etc.
