COMPRESSED AIR CAR TECHNOLOGY: COMPRESSED AIR CAR TECHNOLOGY By DEEPAK SHROFF & ABHAY ODHPAL U.V PATEL COLLEGE OF ENGG. . INTRODUCTION: INTRODUCTION WHAT IS C.A.T.?: WHAT IS C.A.T.? CONSTRUCTION DETAILS : CONSTRUCTION DETAILS Chassis of Air Powered Car WORKING OF C.A.T. ENGINES: WORKING OF C.A.T. ENGINES In principle the technology is very similar to the internal combustion system -compressed air is used to drive a piston in a barrel. It compress air to high pressures in a staged process. It simply reverse the process -decompress the air in stages and in so doing efficiently release energy at each point in the chain. PROCESS DESCRIPTION: PROCESS DESCRIPTION Slide 7: P-V Diagram for Air Engine Slide 9: Graph of crank angle vs. stroke length Slide 10: Graph of crank rpm vs. torque COMPARISON WITH ELECTRICAL VEHICLES: COMPARISON WITH ELECTRICAL VEHICLES Slide 12: AIR POWERED CAR SPECIFICATIONS: SPECIFICATIONS Power source Compressed air: 3200 cubic ft at 4500psi Recharge Charger: On board 5.5kwh 220 volt compressor Recharge time: Less than 3 minutes at air station Alternative Recharge Outlet: 220V electric outlet less than 4 hour Engine Power max. HP (kW): 25(18.3) at 3000 rpm Torque max. Kgm (NM): 6.3(61.7) at 500-2500 rpm Performance Maximum speed: 60 mph Range: 120 miles or 10 hours Acceleration time: 0-30 mph in less than 3 seconds Slide 14: Exterior and Body Overall length : 151 in. Overall width : 68 in. Overall height : 69 in. Weight : 1543 lbs. Engine Mount : Rear Suspension : Front coil spring, rear pneumatic. Steering mechanism : Rack and pinion Body materials : Aluminum & fiberglass Compressed Air Tanks : Carbon Fiber ADVANTAGES: ADVANTAGES Zero emission vehicle. No fossil fuel required. Operating cost 75% less as compare to the gasoline engines. Price is also less then half of the electric vehicles. ADVANTAGES: ADVANTAGES The recharging of tank can be done at house. Light weight provides good road-holding due to low center of gravity and low energy consumption. The recharging time is much more less that EV. DISADVANTAGE: DISADVANTAGE It can’t give much higher speed. The recharging stations. CONCLUSION: CONCLUSION THANK YOU.: THANK YOU.
