We have developed tubeless tires but that’s not a perfect solution, so there is a serious need of i mprovement in this area. In this paper the compressed air is used to maintain the pressure in the tire using pneumatic pipes. This is a very basic concept which uses compressor power to maintain the pressure of a tire, while running using pressure gauges and leak proof connection. This tech- nique allows us to drive a punctured vehicle which increases safety, comfort & saves time. This paper suggests a new technique to- wards one more improvement in our automobile industry. Keywords- Pneumatic pipes, Leak proof connection. 1 INTRODUCTION When we travel in car & if there is prickle or punc- ture in a tire then we need to wait and we can’t reach the destination in time. If we use this system then we can drive that punctured vehicle without any trouble, so efficiency increases. We do not need more cost to invest in this system. With this system we can fill air in moving vehicle easily just attaching few components to the engine or battery. 1. Compressor 2. pipes 3. Non return valve 4. Pressure gauges 5. Leak proof connection etc... 2. CONSTRUCTION initially we connect the compressor to the engine sub- assembly through the belt drive mechanism. Then through the non-return valve, we connect the compressor by pneumatic pipe or hoses to the wheel assembly. Here with the help of leak proof connection we connect this pipe to the tire valve. A gauge is connected to the pneumatic pipe such that it will sense the change in pressure in the tire. The piping arrangement near the tire is done according to the available space. If possible it will be connected from inner side of the wheel else from outer side, if connected from outside its connection will be as shown in the diagram (rough). 3. COMPRESSOR Normal sized compressor with capacity of around 150 psi is required for the proper functioning. The cost of this compressor is around Rs.3000-3500. It can be easily mounted on the engine assembly since its size is small. Normally if op- erated on battery it will operate on 12V DC supply. That is again an advantage of this system. 4. HOSES Standard hoses with diameter of 1-1.5 cm are required which must sustain pressure equal to that of compressor. V. LEAK PROOF CONNECTION (LPC) w
