Compressed air Vehicle ( CAV )

Abstract

In the field of combustion engines, it is well know that fuels such as gasoline, diesel, and ethanol are used in a combustion process to power engines . however , its also well known that the use of such fuels generates byproducts which are harmful to the environment. Further , aside from environmental concerns, the use of such fuels is costly to the consumer. In view of these concerns, its desirable to at least substantially reduce , if not eliminate, the use of combustible fuels . one source of power is compressed air, or pneumatics. Several devices have been developed for using pneumatic power to operate engines. In this proposed project an air-operated engine system used for driving a vehicle by means of compressed air from a rechargeable air storage tank. The engine used in the system has cylinders containing driving pistons connected to a crankshaft. Compressed air from the storage tank is supplied at a regulated pressure to the cylinders in power strokes by means of solenoid valves and then the air is exhausted from the cylinders at the ends of the power strokes exhausting by means of the same valves. The solenoid valves are operated by a distributor which controlled by electrical signal from the crankshaft. The air is compressed by compressor which operated electrically.
