Tire Pressure Inflation System

Tire pressure plays an important role in ensuring safe and economical driving. Improperly inflated tires can affect stopping distance increases the chance of tire delaminating, reduces the handling characteristics which in turn affects the control of vehicle. Even then, many vehicles with under inflated tires are observed to be on the road due to the unawareness of the fact that properly inflated tires can safe tire life up to 20%, save fuel from 4% to 10%, increase braking efficiency up to 20%, lightens the steering system and can help in ease self-steer. In every month, there is a pressure drop of 10KPa to 20KPa in a car. Drop of each 10KPa is equivalent to adding a 70Kg person into the car and causes over loading due to virtual passenger condition in the car. To address this problem, an automatic tire pressure inflation system has been idealized to ensure correct pressure is inflated into the tires regardless of the setting on the pressure source. The device will alert the user upon reaching the appropriate pressure by a LED indication. The system consists of a storage tank, dc compressor, pressure switch, battery and solenoid valve. Air taken from the atmosphere is compressed in the compressor and is transferred to the tire when the pressure reduces from the recommended value.
